The Seebeck effect is the conversion of temperature differences directly into electricity and is named for German-Estonian physicist Thomas Johann Seebeck, who, in 1821 discovered that a compass needle would be deflected by a closed loop formed by two metals joined in two places, with a temperature difference between the junctions. This was because the metals responded differently to the temperature difference, creating a current loop and a magnetic field. Seebeck did not recognize there was an electric current involved, so he called the phenomenon the thermomagnetic effect. Danish physicist Hans Christian Ørsted rectified the mistake and coined the term "thermoelectricity". The voltage created by this effect is of the order of several microvolts per kelvin difference. One such combination, copper-constantan, has a Seebeck coefficient of 41 microvolts per kelvin at room temperature.[2]The voltage V developed can be derived from:where S A and S B are the thermopowers (Seebeck coefficient) of metals A and B as a function of temperature and T1 and T2 are the temperatures of the two junctions. TheSeebeck coefficients are non-linear as a function of temperature, and depend on theconductors' absolute temperature, material, and molecular structure. If the Seebeckcoefficients are effectively constant for the measured temperature range, the aboveformula can be approximated as:The Seebeck effect is used in the thermocouple to measure a temperature difference;absolute temperature may be found by setting one end to a known temperature. Ametal of unknown composition can be classified by its thermoelectric effect if ametallic probe of known composition, kept at a constant temperature, and is held incontact with it. Industrial quality control instruments use this as thermoelectric alloysorting to identify metal alloys. Thermocouples in series form a thermopile,sometimes constructed in order to increase the output voltage, since the voltageinduced over each individual couple is small. Thermoelectric generators are used forcreating power from heat differentials and exploit this effect.Peltier effectThe Peltier effect is the presence of heat at an electrified junction of two different metals and is named for French physicist Jean-Charles Peltier, who discovered it in 1834. When a current is made to flow through a junction composed of materials A and B, heat is generated at the upperjunction at T2, and absorbed at the lower junction at T1. The Peltier heat absorbed by the lower junction per unit time is equal towhere ΠAB is the Peltier coefficient for the thermocouple composed of materials A and B and ΠA(ΠB) is the Peltier coefficient of material A (B). Π varies with the material's temperature and its specific composition: p-type silicon typically has a positive Peltier coefficient below ~550 K, but n-type silicon is typically negative.The Peltier coefficients represent how much heat current is carried per unit charge through a given material. Since charge current must be continuous across a junction, the associated heat flow will develop a discontinuity if ΠA and ΠB are different. Depending on the magnitude of the current, heat must accumulate or deplete at the junction due to a non-zero divergence there caused by the carriers attempting to return to the equilibrium that existed before the current was applied by transferring energy from one connector to another. Individual couples can be connected in series to enhance the effect. Thermoelectric heat pumps exploit this phenomenon, as do thermoelectric cooling devices found in refrigeratorsThomson effectThe Thomson effect was predicted and subsequently observed by Lord Kelvin in 1851. It describes the heating or cooling of a current-carrying conductor with a temperature gradient.Any current-carrying conductor (except for a superconductor) with a temperature difference between two points either absorbs or emits heat, depending on the material. If a current density J is passed through a homogeneous conductor, the heat production q per unit volume is:where ρ is the resistivity of the material, dT/dx is the temperature gradient along the wireand μ is the Thomson coefficient. The first term is the Joule heating, which does not change in sign; the second term is the Thomson heating, which follows J changing sign.In metals such as zinc and copper, whose temperature is directly proportional to their potential, when current moves from the hotter end to the colder end, there is a generation of heat and the positive Thomson effect occurs.[citation needed] Conversely, in metals such as cobalt, nickel, and iron, whose temperature is inversely proportional to their potential, when current moves from the hotter end to the colder end, there is an absorption of heat and the negative Thomson effect occurs.If the Thomson coefficient of a material is measured over a wide temperature range, it can be integrated using the Thomson relations to determine the absolute values for the Peltier and Seebeck coefficients. This needs to be done only for one material, since the other values can be determined by measuring pairwise Seebeck coefficients in thermocouples containing the reference material and then adding back the absolute thermopower of the reference material.Lead is commonly stated to have a Thomson coefficient of zero; in fact, it is non-zero, albeit being very small.[5] In contrast, the thermoelectric coefficients of all known superconductors are zeroFigure of meritThe figure of merit Z for thermoelectric devices is defined aswhere σ is the electrical conductivity, κ is the thermal conductivity, and S is the Seebeck coefficient. The dimensionless figure of merit ZT is formed by multiplying Z with the average temperature.A greater ZT indicates a greater thermodynamic efficiency, subject to certain provisions, particularly that the two materials in the couple have similar Z. ZT is therefore a method for comparing the potential efficiency of devices using different materials. Values of 1 are considered good; values in the 3–4 range are essential for thermoelectrics to compete with mechanical devices in efficiency. To date, the best reported ZT values are in the 2–3 range. Currently this goal of high ZT values is referred to as: "high-figure-of-merit" [6][7][8] Much of the research in thermoelectric materials has focused on increasing S and reducing κ by manipulating the nanostructure of the materials.[citation needed][edit]Device efficiencyThe efficiency of a thermoelectric device for electricity generation is given by η, defined asThe maximum efficiency ηmax is defined aswhere T H is the temperature at the hot junction and T C is the temperature at the surface beingcooled. is the modified dimensionless figure of merit, which takes into consideration the thermoelectric capacity of both thermoelectric materials being used in the device and is defined aswhere ρ is the electrical resistivity, is the average temperature between the hot and cold surfaces and the subscripts n and p denote properties related to the n- and p-typesemiconducting thermoelectric materials, respectively. Since thermoelectric devices are heat engines, their efficiency is limited by the Carnot efficiency, hence the T H and T C terms in . Regardless, the coefficient of performance of current commercial thermoelectric refrigerators ranges from 0.3 to 0.6, one-sixth the value of traditional vapor-compression refrigerators.[9][edit]ApplicationsSee also: Thermoelectric materials[edit]Seebeck effectMain article: Thermoelectric generatorThe Seebeck effect is used in the thermoelectric generator, which functions like a heat engine, but is less bulky, has no moving parts, and is typically more expensive and less efficient. These have a use in power plants for converting waste heat into additional power (a formof energy recycling), and in automobiles as automotive thermoelectric generators(ATGs) for increasing fuel efficiency. Space probes often use radioisotope thermoelectric generators with the same mechanism but using radioisotopes to generate the required heat difference.[edit]Peltier effectMain article: Thermoelectric coolingThe Peltier effect can be used to create a refrigerator which is compact and has no circulating fluid or moving parts; such refrigerators are useful in applications where their advantages out weigh the disadvantage of their very low efficiency.[edit]Temperature measurementThermocouples and thermopiles are devices that use the Seebeck effect to measure the temperature difference between two objects, one connected to a voltmeter and the other to the probe. The temperature of the voltmeter, and hence that of the material being measured by the probe, can be measured separately using cold junction compensation techniques。

(完整版)传感器专业名词英⽂解释1. Briefly define the following terms1) TransducerA transducer is a device that converts a signal from one physicalform to a corresponding signal having a different physical form .2) SensorA sensor converts a physical signal into an electrical signal (i.e., amicrophone).3) ActuatorAn actuator is a device that converts electrical energy into physical energy (i.e.,a loudspeaker).4) LinearityThe linearity describes the closeness between the calibration curve and a specified straight line.5) SensitivityThe sensitivity is defined in terms of the relationship between input physicalsignal and output electrical signal. It is generally the ratio between a smallchange in electrical signal to a small change in physical signal. The sensitivity isthe slope of the calibration curve.6) HysteresisThe hysteresis refers to the difference between two output values thatcorrespond to the same input, depending on the direction (increasing ordecreasing) of successive input values. That is, similarly to the magnetizationin ferromagnetic materials, it can happen that the output corresponding to agiven input depends on whether the previous input was higher or lower than thepresent one.Some sensors do not return to the same output value when the input stimulus iscycled up or down. The width of the expected error in terms of the measuredquantity is defined as the hysteresis.7) RepeatabilityThe repeatability is the closeness of agreement between successive resultsobtained with the same method under the same conditions and in a short timeinterval.%100y σ)3~2(δFS ?=Rδ—sample standard deviation8) Strain (mechanical)Fractional change in length ΔL/L.9) Gage factorThe gage factor is defined as the fractional change in resistance divided by the strain.10) Piezoresistive effectThe change in resistivity as a result of a mechanical stress is called thepiezoresistive effect.11)direct piezoelectric effect.the phenomenon of generation of a voltage under mechanical stress is referred to as the piezoelectric effect.12)converse piezoelectric effect.The mechanical strain produced in the crystal under electric stress is called the converse piezoelectric effect.13)Numerical ApertureThe "acceptance cone" defines how much light will be accepted into the fiber andultimately how much remains in the fiber, and is referred to as the numerical aperture. 14)Extrinsic sensorThe optical fiber plays no part in achieving the modulating but simply acts as atransmission medium ; these are extrinsic sensors.15)Intrinsic sensors (fiber optic sensor)The optical fiber plays a major role in modulating the energy from the source; these are referred to as intrinsic sensors.16)Humiditya quantity representing the amount of water vapor in the atmosphere or a gas17)Absolute humidityAbsolute humidity is the mass of water vapor per unit volume of air.18)Relative humidityThe ratio of the actual vapor density to the theoretical maximum (saturation) vapordensity at the same temperature, expressed as a percentage. The relative humidity is the ratio of the actual vapor pressure to the saturation vapor pressure at given temperature. 19)Peltier effectWhen two dissimilar metals are connected together, a small voltage called athermojunction voltage is generated at the junction. This is called the Peltier effect.20)Law of Homogeneous ConductorsFor a given pair of homogeneous conductors forming a closed loop, the Seebeck emf depends only on the temperatures of the junctions, and not on the temperature distribution along the length of the conductors.21)Law of intermediate metalsA third (intermediate) metal wire can be inserted in series with one of the wires withoutchanging the voltage reading (provided that the two new junctions are at the sametemperature).If there is a third metal introduced into the thermocouple circuit , it will not adverselyeffect the reading, if and only if the two junctions of the third metal are at the sametemperatures .22)Bernoulli’s theoremBernoulli’s equation states that energy is approximately conserved across a constriction ina pipe.Bernoulli’s equation: P/(ρ?g) + ?v2/g + y = constant(ρ=density;g=acceleration of gravity ; v=fluid velocity; y=elevation )2. Describe the following devices and how they work1) Strain gageThe strain gauge usually consists of wire, baking, thinpaper, and lead welded. The wireis arranged in the form of a grid in order to obtain higher resistances.2) Parallel plate Capacitive SensorThe parallel plate Capacitive Sensor is a function of the distance d (cm) between theelectrodes of a structure, the surface area A (cm2) of the electrodes, and the permittivity ε0(F/m 1085.812-?for air) of the dielectric between the electrodes; therefore:d Ad AC 0r εεε==3) Differential Capacitive SensorA differential capacitor consists of two variable capacitors so arranged that they undergothe same change, but in opposite directions. The amplifier circuit, depending on itsconfiguration, can generate a voltage proportional to C1 - C2 or C1/C2 or (C1 - C2)/(C1 +C2).4) Variable Reluctance SensorsA typical single-coil variable-reluctance displacement sensor is illustrated in the Figurebelow. The sensor consists of three elements: a ferromagnetic core, a variable air gap, anda ferromagnetic plate.Based on change in the reluctance of a magnetic flux path. Self-inductance L of the coil is: Reluctance can be given as: 5) Variable-Reluctance TachogeneratorsIt consists of a ferromagnetic, toothed wheel attached to a rotating shaft, a coil and amagnet. The wheel rotates in close proximity to the pole piece, thus causing the flux linkedby thecoil to change. The sensors output depends on the speed of the rotation of the wheeland the number of teeth.6) LVDTAn LVDT consists of three coils, a form and a core. The coils are wound on a hollow form.The primary is excited by some ac source. Flux formed by the primary is linked to the twosecondary coils, inducing an ac voltage in each coil. A core is inside the former. It canslide freely through the center of the form.In many applications, the two secondary coils are connected in series opposition.Then the two voltages will subtract; that is, the differential voltage is formed. When thecore is centrally located, the net voltage is zero. When the core is moved to one side, thenet voltage will increase.7) Compression Mode Piezoelectric Accelerometers Upright compression designs sandwich the piezoelectric crystal between a seismic mass2m WL R =0m l R S µµ=and rigid mounting base. A pre- load stud or screw secures the sensing element to themounting base.When the sensor is accelerated, the seismic mass increases or decreases the amount of compression force acting upon the crystal, and a proportional electrical output results.8)Shear mode accelerometerShear mode accelerometer designs bond, or “sandwich,” the sensing material between a center post and seismic mass. A compression ring or stud applies a preload force required to create a rigid linear structure. Under acceleration, the mass causes a shear stress to be applied to the sensing material. This stress results in a proportional electrical output by the piezoelectric material. They represent the traditional or historical accelerometer design.9)PsychrometerA psychrometer contains two identical thermometers. One sensor, the dry bulb ,measures the ambient temperature. The other sensor, the wet bulb, is in a wetted condition.In operation, water evaporation cools the wetted thermometer, resulting in a measurable difference between it and the ambient, or dry bulb measurement. When the wet bulbreaches its maximum temperature depression, the humidity is determined by comparing the wet bulb/dry bulb temperatures on a psychrometric chart10)Dunmore sensorThe Dunmore sensor uses a dilute lithium chloride solution in a polyvinylacetate binder on an insulating substrate. The resistance of the sensor, measured between a bifilar grid, is a function of the r.h. of the surrounding air.11)MOS CapacitorCCDs are typically fabricated on a p-type substrate. In order to implement the “buried” channel a thin n-type region is formed on its surface. A insulator, in the form of a silicon dioxide layer is grown on top of the n-region. Thecapacitor is finished off by placing one or more electrodes, also called gates, on top of the insulating silicon dioxide.12)Full frame transfer (FFT)It consists of a parallel CCD shift register, a serial CCD shift register and a signal sensing output amplifierThe image pixel are vertically transferred into a horizontal serial register, and the charges are horizontally shifted out.13)Interline transfer (ILT)The readout regions are interspaced between the imaging regions, and are shielded from the light.At the end of the integration period, the charges are transferred horizontally to the vertical readout registers in parallel, and then read out line-by-line in a manner similar to FFT.ILT does avoid smear but with the cost of the sensitive imaging areas.14)Frame transfer (FT)The array is grouped into two sections: the image section and the storage section. These two sections are identical, except that the storage section is shielded from the light. During the readout, charges are transfered line-by-line into the storage section by applying the same clocking to both sections. At the end of the integration period, charges in the storagesection are transferred line-by-line a manner similar to FFT.15)proximity sensorsProximity sensors detect objects that are near but without touching them. These sensors are used for near-field robotic operations.16)Time-of-flight sensorsTime-of-flight sensors estimate the range by measuring the time elapsed between thetransmission and return of a pulse17)Triangulation sensorsTriangulation sensors measure range by detecting a given point on the object surface from two different points of view at a known distance from each other. Knowing this distance and the two view angles from the respective points to the aimed surface point, a simple geometrical operation yields the range.18)Thermal Infrared DetectorsThermal infrared detectors convert incoming radiation into heat, raising the temperature of the thermal detector.19)Photon-type detectorsPhoton-type detectors react to the photons emitted by the object. The infrared radiation causes changes in the electrical properties of photon-type detectors.There are two main types of photon infrared detectors. One is called Photoconductive detector, which exhibit increased conductivity with received radiation. Another is named as Photovoltaic detector, this device converts received radiation into electric current.20)shock tubeConstruction of a shock tube is quite simple: it consists of a long tube, closed at both ends, separated into two chambers by a diaphragm, as shown in the Fig. below. A pressure differential is built up across the diaphragm, and the diaphragm is burst, either directly by the pressure differential or initiated by means of an externally controlled probe. Rupturing of the diaphragm causes a shock wave.The shock tube provides the nearest thing to a transient pressure “standard.”21)ThermocoupleA thermocouple consists of two electrical conductors made of different metals that are joined at one end.Note particularly that two junctions are always required. In general, one sense the desired or unknown temperature; this one we shall call the hot or measuring junction. The second will usually be maintained at a known fixed temperature; this one we shall refer to as the cold or reference junction. When the two junctions are at different temperatures, a voltage is developed across the junction.22)Bimetallic strip thermometerTwo dissimilar metals are bonded together into what is called a bimetallic strip. Since two metals have different coefficient of thermal expansion, one metal will expands more than does another metal as temperature increases, causing the bimetallic strip to curl upwards as sketched.23)RTDA resistance temperature detector is basically either a long, small diameter metal wirewound in a coil or an etched grid on a substrate, much like a strain gage. The resistance ofan RTD increases with increasing temperature.24)Three-wire BridgeA clever circuit designed to eliminate the lead wire resistance error is called a three-wireRTD bridge circuit, as sketched to the right.If wires A and B are perfectly matched in length (wires A and B have the same length, and thus the same resistance,), their impedance effects will cancel because each is in anopposite leg of the bridge. The third wire, C, acts as a sense lead and carries no current.25)ThermistorA thermistor is similar to an RTD, but a semiconductor material is usedinstead of a metal. A change in temperature causes the electrical resistance of the semiconductor material to change. P ositive temperature coefficient (PTC) and and negative temperature coefficient (NTC) units are available.26)Seismic (Absolute) Acc eleration PickupsIt consistis of a mass, a spring, and a damper arrangement, as shown in the Figure below.Fig……..y(t)= the absolute displacement of the mass Mx(t)= the absolute displacement of the basez-y=)()(txtz —the relative motion between the mass and the basem —massc —damping constantk —spring constantSeismic (Absolute) Displacement PickupsThe relative displacement z (the output of the sensor) is proportional to the applied displacement. A low value of ωn is needed (ωn should be much less than the lowest vibration frequency for accurate displacement measurement. )Seismic AccelerometerThe relative displacement z ( the output of the sensor) is proportional to the appliedacceleration. a high ωn is needed to measure accurately high-frequency. Increasing ωn will increase the range of frequency for which the amplitude-ratio curve is relatively flat;27)Seismic Velocity Pickup (moving coil type)One type of velocity transducer is based on a linear generator. When a coil cuts the magnetic field lines around a magnet, a voltage is induced in the coil, and this voltage is dependent on the speed of the coil relative to the magnet. The velocity pickup is designed like a displacement pickup, to have a low value of wn and to operate at angular frequencies well above wn so that the motion of the seismic mass is virtually the same as that of the casing but (almost) opposite in phase.28)The Orifice Plate FlowmetersAn orifice plate is a restriction with an opening smaller than the pipe diameter which is inserted in the pipe; Because of the smaller area the fluid velocity increases, causing acorresponding decrease in pressure.The flow ratee can be calculated from the measured pressure drop across the orifice plate 29)Ultrasonic Flowmeters Ultrasonic Doppler Method:Doppler Equation :v f= K ? Δf ;Doppler ultrasonic flowmeters reflect ultrasonic energy from particles, bubbles and/or eddies flowing in the fluid.Ultrasonic Transit-Time Method:The time difference between ultrasonic energy moving upstream and downstream in the fluid is used to determine fluid Velocity.Because transmitter-receiver B is situated downstream withrespect to A, the sound wave train from A to B will arrive soonerthan the train from B to A . This implies that the execution timefrom A to B is shorter than that from B to A.30)Electromagnetic FlowmetersThe measurement principle is based on Faraday’s Law of Magnetic Induction :ahomogeneous magnetic field is built up. An electrically conducting liquid flowsthrough this magnetic field.By the movement of the electrical conductor (liquid) a current gets induced which isproportional to the average flow velocity and the magnet field strength.。

位移传感器-(中英对照)
位移传感器位移传感器又称为线性传感器,它分为电感式位移传感器,电容式位移传感器,光电式位移传感器,位移传感器超声波式位移传感器,霍尔式位移传感器。
电感式位移传感器是一种属于金属感应的线性器件,接通电源后,在开关的感应面将产生一个交变磁场,当金属物体接近此感应面时,金属中则产生涡流而吸取了振荡器的能量,使振荡器输出幅度线性衰减,然后根据衰减量的变化来完成无接触检测物体的目的。
简介电感式位移传感器具有无滑动触点,工作时不受灰尘等非金属因素的影响,并且低功耗,长寿命,可使用在各种恶劣条件下。
位移传感器主要应用在自动化装备生产线对模拟量的智能控制。
位移是和物体的位置在运动过程中的移动有关的量,位移的测量方式所涉及的范围是相当广泛的。
小位移通常用应变式、电感式、差动变压器式、涡流式、霍尔传感器来检测,大的位移常用感应同步器、光栅、容栅、磁栅等传感技术来测量。
其中光栅传感器因具有易实现数字化、精度高(目前分辨率最高的可达到纳米级)、抗干扰能力强、没有人为读数误差、安装方便、使用可靠等优点,在机床加工、检测仪表等行业中得到日益广泛的应用。
原理计量光栅是利用光栅的莫尔条纹现象来测量位移的。
“莫尔”原出于法文Moire,意思是水波纹。
几百年前法国丝绸工人发现,当两层薄丝绸叠在一起时,将产生水波纹状花样;如果薄绸子相对运动,则花样也跟着移动,这种奇怪的花纹就是莫尔条纹。
一般来说,只要是有一定周期的曲线簇重叠起来,便会产生莫尔条纹。
计量光栅在实际应用上有透射光栅和反射光栅两种;按其作用原理又可分为辐射光栅和相位光栅;按其用途可分为直线光栅和圆光栅。
下面以透射光栅为例加以讨论。
透射光栅尺上均匀地刻有平行的刻线即栅线,a为刻线宽,b为两刻线之间缝宽,W=a+b称为光栅栅距。
目前国内常用的光栅每毫米刻成10、25、50、100、250条等线条。
光栅的横向莫尔条纹测位移,需要两块光栅。
一块光栅称为主光栅,它的大小与测量范围相一致;另一块是很小的一块,称为指示光栅。
(完整版)传感器专业名词英文解释
1. Briefly define the following terms1) TransducerA transducer is a device that converts a signal from one physicalform to a corresponding signal having a different physical form .2) SensorA sensor converts a physical signal into an electrical signal (i.e., amicrophone).3) ActuatorAn actuator is a device that converts electrical energy into physical energy (i.e.,a loudspeaker).4) LinearityThe linearity describes the closeness between the calibration curve and a specified straightline.5) SensitivityThe sensitivity is defined in terms of the relationship between input physicalsignal and output electrical signal. It is generally the ratio between a smallchange in electrical signal to a small change in physical signal. The sensitivity isthe slope of the calibration curve.6) HysteresisThe hysteresis refers to the difference between two output values thatcorrespond to the same input, depending on the direction (increasing ordecreasing) of successive input values. That is, similarly to the magnetizationin ferromagnetic materials, it can happen that the output corresponding to agiven input depends on whether the previous input was higher or lower than thepresent one.Some sensors do not return to the same output value when the input stimulus iscycled up or down. The width of the expected error in terms of the measuredquantity is defined as the hysteresis.7) RepeatabilityThe repeatability is the closeness of agreement between successive resultsobtained with the same method under the same conditions and in a short timeinterval.%100y σ)3~2(δFS ⨯=Rδ—sample standard deviation8) Strain (mechanical)Fractional change in length ΔL/L.9) Gage factorThe gage factor is defined as the fractional change in resistance divided by the strain.10) Piezoresistive effectThe change in resistivity as a result of a mechanical stress is called thepiezoresistive effect.11)direct piezoelectric effect.the phenomenon of generation of a voltage under mechanical stress is referred to as the piezoelectric effect.12)converse piezoelectric effect.The mechanical strain produced in the crystal under electric stress is called the converse piezoelectric effect.13)Numerical ApertureThe "acceptance cone" defines how much light will be accepted into the fiber andultimately how much remains in the fiber, and is referred to as the numerical aperture. 14)Extrinsic sensorThe optical fiber plays no part in achieving the modulating but simply acts as atransmission medium ; these are extrinsic sensors.15)Intrinsic sensors (fiber optic sensor)The optical fiber plays a major role in modulating the energy from the source; these are referred to as intrinsic sensors.16)Humiditya quantity representing the amount of water vapor in the atmosphere or a gas17)Absolute humidityAbsolute humidity is the mass of water vapor per unit volume of air.18)Relative humidityThe ratio of the actual vapor density to the theoretical maximum (saturation) vapordensity at the same temperature, expressed as a percentage. The relative humidity is the ratio of the actual vapor pressure to the saturation vapor pressure at given temperature. 19)Peltier effectWhen two dissimilar metals are connected together, a small voltage called athermojunction voltage is generated at the junction. This is called the Peltier effect.20)Law of Homogeneous ConductorsFor a given pair of homogeneous conductors forming a closed loop, the Seebeck emf depends only on the temperatures of the junctions, and not on the temperature distribution along the length of the conductors.21)Law of intermediate metalsA third (intermediate) metal wire can be inserted in series with one of the wires withoutchanging the voltage reading (provided that the two new junctions are at the sametemperature).If there is a third metal introduced into the thermocouple circuit , it will not adverselyeffect the reading, if and only if the two junctions of the third metal are at the sametemperatures .22)Bernoulli’s theoremBernoulli’s equation states that energy is approximately conserved across a constriction ina pipe.Bernoulli’s equation: P/(ρ•g) + ½v2/g + y = constant(ρ=density;g=acceleration of gravity ; v=fluid velocity; y=elevation )2. Describe the following devices and how they work1) Strain gageThe strain gauge usually consists of wire, baking, thinpaper, and lead welded. The wireis arranged in the form of a grid in order to obtain higher resistances.2) Parallel plate Capacitive SensorThe parallel plate Capacitive Sensor is a function of the distance d (cm) between theelectrodes of a structure, the surface area A (cm2) of the electrodes, and the permittivity ε0(F/m 1085.812-⨯for air) of the dielectric between the electrodes; therefore:d Ad AC 0r εεε==3) Differential Capacitive SensorA differential capacitor consists of two variable capacitors so arranged that they undergothe same change, but in opposite directions. The amplifier circuit, depending on itsconfiguration, can generate a voltage proportional to C1 - C2 or C1/C2 or (C1 - C2)/(C1 +C2).4) Variable Reluctance SensorsA typical single-coil variable-reluctance displacement sensor is illustrated in the Figurebelow. The sensor consists of three elements: a ferromagnetic core, a variable air gap, anda ferromagnetic plate.Based on change in the reluctance of a magnetic flux path. Self-inductance L of the coil is: Reluctance can be given as:5) Variable-Reluctance TachogeneratorsIt consists of a ferromagnetic, toothed wheel attached to a rotating shaft, a coil and amagnet. The wheel rotates in close proximity to the pole piece, thus causing the flux linkedby thecoil to change. The sensors output depends on the speed of the rotation of the wheeland the number of teeth.6) LVDTAn LVDT consists of three coils, a form and a core. The coils are wound on a hollow form.The primary is excited by some ac source. Flux formed by the primary is linked to the twosecondary coils, inducing an ac voltage in each coil. A core is inside the former. It canslide freely through the center of the form.In many applications, the two secondary coils are connected in series opposition.Then the two voltages will subtract; that is, the differential voltage is formed. When thecore is centrally located, the net voltage is zero. When the core is moved to one side, thenet voltage will increase.7) Compression Mode Piezoelectric Accelerometers Upright compression designs sandwich the piezoelectric crystal between a seismic mass2m WL R =0m l R S μμ=and rigid mounting base. A pre- load stud or screw secures the sensing element to themounting base.When the sensor is accelerated, the seismic mass increases or decreases the amount of compression force acting upon the crystal, and a proportional electrical output results.8)Shear mode accelerometerShear mode accelerometer designs bond, or “sandwich,” the sensing material between a center post and seismic mass. A compression ring or stud applies a preload force required to create a rigid linear structure. Under acceleration, the mass causes a shear stress to be applied to the sensing material. This stress results in a proportional electrical output by the piezoelectric material. They represent the traditional or historical accelerometer design.9)PsychrometerA psychrometer contains two identical thermometers. One sensor, the dry bulb ,measures the ambient temperature. The other sensor, the wet bulb, is in a wetted condition.In operation, water evaporation cools the wetted thermometer, resulting in a measurable difference between it and the ambient, or dry bulb measurement. When the wet bulbreaches its maximum temperature depression, the humidity is determined by comparing the wet bulb/dry bulb temperatures on a psychrometric chart10)Dunmore sensorThe Dunmore sensor uses a dilute lithium chloride solution in a polyvinylacetate binder on an insulating substrate. The resistance of the sensor, measured between a bifilar grid, is a function of the r.h. of the surrounding air.11)MOS CapacitorCCDs are typically fabricated on a p-type substrate. In order to implement the “buried” channel a thin n-type region is formed on its surface. A insulator, in the form of a silicon dioxide layer is grown on top of the n-region. Thecapacitor is finished off by placing one or more electrodes, also called gates, on top of the insulating silicon dioxide.12)Full frame transfer (FFT)It consists of a parallel CCD shift register, a serial CCD shift register and a signal sensing output amplifierThe image pixel are vertically transferred into a horizontal serial register, and the charges are horizontally shifted out.13)Interline transfer (ILT)The readout regions are interspaced between the imaging regions, and are shielded from the light.At the end of the integration period, the charges are transferred horizontally to the vertical readout registers in parallel, and then read out line-by-line in a manner similar to FFT.ILT does avoid smear but with the cost of the sensitive imaging areas.14)Frame transfer (FT)The array is grouped into two sections: the image section and the storage section. These two sections are identical, except that the storage section is shielded from the light. During the readout, charges are transfered line-by-line into the storage section by applying the same clocking to both sections. At the end of the integration period, charges in the storagesection are transferred line-by-line a manner similar to FFT.15)proximity sensorsProximity sensors detect objects that are near but without touching them. These sensors are used for near-field robotic operations.16)Time-of-flight sensorsTime-of-flight sensors estimate the range by measuring the time elapsed between thetransmission and return of a pulse17)Triangulation sensorsTriangulation sensors measure range by detecting a given point on the object surface from two different points of view at a known distance from each other. Knowing this distance and the two view angles from the respective points to the aimed surface point, a simple geometrical operation yields the range.18)Thermal Infrared DetectorsThermal infrared detectors convert incoming radiation into heat, raising the temperature of the thermal detector.19)Photon-type detectorsPhoton-type detectors react to the photons emitted by the object. The infrared radiation causes changes in the electrical properties of photon-type detectors.There are two main types of photon infrared detectors. One is called Photoconductive detector, which exhibit increased conductivity with received radiation. Another is named as Photovoltaic detector, this device converts received radiation into electric current.20)shock tubeConstruction of a shock tube is quite simple: it consists of a long tube, closed at both ends, separated into two chambers by a diaphragm, as shown in the Fig. below. A pressure differential is built up across the diaphragm, and the diaphragm is burst, either directly by the pressure differential or initiated by means of an externally controlled probe. Rupturing of the diaphragm causes a shock wave.The shock tube provides the nearest thing to a transient pressure “standard.”21)ThermocoupleA thermocouple consists of two electrical conductors made of different metals that are joined at one end.Note particularly that two junctions are always required. In general, one sense the desired or unknown temperature; this one we shall call the hot or measuring junction. The second will usually be maintained at a known fixed temperature; this one we shall refer to as the cold or reference junction. When the two junctions are at different temperatures, a voltage is developed across the junction.22)Bimetallic strip thermometerTwo dissimilar metals are bonded together into what is called a bimetallic strip. Since two metals have different coefficient of thermal expansion, one metal will expands more than does another metal as temperature increases, causing the bimetallic strip to curl upwards as sketched.23)RTDA resistance temperature detector is basically either a long, small diameter metal wirewound in a coil or an etched grid on a substrate, much like a strain gage. The resistance ofan RTD increases with increasing temperature.24)Three-wire BridgeA clever circuit designed to eliminate the lead wire resistance error is called a three-wireRTD bridge circuit, as sketched to the right.If wires A and B are perfectly matched in length (wires A and B have the same length, and thus the same resistance,), their impedance effects will cancel because each is in anopposite leg of the bridge. The third wire, C, acts as a sense lead and carries no current.25)ThermistorA thermistor is similar to an RTD, but a semiconductor material is usedinstead of a metal. A change in temperature causes the electrical resistance of the semiconductor material to change. P ositive temperature coefficient (PTC) and and negative temperature coefficient (NTC) units are available.26)Seismic (Absolute) Acc eleration PickupsIt consistis of a mass, a spring, and a damper arrangement, as shown in the Figure below.Fig……..y(t)= the absolute displacement of the mass Mx(t)= the absolute displacement of the basez-y=)()(txtz —the relative motion between the mass and the basem —massc —damping constantk —spring constantSeismic (Absolute) Displacement PickupsThe relative displacement z (the output of the sensor) is proportional to the applied displacement. A low value of ωn is needed (ωn should be much less than the lowest vibration frequency for accurate displacement measurement. )Seismic AccelerometerThe relative displacement z ( the output of the sensor) is proportional to the appliedacceleration. a high ωn is needed to measure accurately high-frequency. Increasing ωn will increase the range of frequency for which the amplitude-ratio curve is relatively flat;27)Seismic Velocity Pickup (moving coil type)One type of velocity transducer is based on a linear generator. When a coil cuts the magnetic field lines around a magnet, a voltage is induced in the coil, and this voltage is dependent on the speed of the coil relative to the magnet. The velocity pickup is designed like a displacement pickup, to have a low value of wn and to operate at angular frequencies well above wn so that the motion of the seismic mass is virtually the same as that of the casing but (almost) opposite in phase.28)The Orifice Plate FlowmetersAn orifice plate is a restriction with an opening smaller than the pipe diameter which is inserted in the pipe; Because of the smaller area the fluid velocity increases, causing acorresponding decrease in pressure.The flow ratee can be calculated from the measured pressure drop across the orifice plate 29)Ultrasonic FlowmetersUltrasonic Doppler Method:Doppler Equation :v f= K • Δf ;Doppler ultrasonic flowmeters reflect ultrasonic energy from particles, bubbles and/or eddies flowing in the fluid.Ultrasonic Transit-Time Method:The time difference between ultrasonic energy moving upstream and downstream in the fluid is used to determine fluid Velocity.Because transmitter-receiver B is situated downstream withrespect to A, the sound wave train from A to B will arrive soonerthan the train from B to A . This implies that the execution timefrom A to B is shorter than that from B to A.30)Electromagnetic FlowmetersThe measurement principle is based on Faraday’s Law of Magnetic Induction :ahomogeneous magnetic field is built up. An electrically conducting liquid flowsthrough this magnetic field.By the movement of the electrical conductor (liquid) a current gets induced which isproportional to the average flow velocity and the magnet field strength.。
