DatasheetMiniature ultrasonic sensors with TEACH-mode programming•Fast, easy-to-use TEACH-Mode programming; no potentiometer adjustments•Ultra-compact housing•One discrete output: NPN or PNP, depending on model•Two bi-colored status LEDs•Rugged encapsulated version for harsh environments•Choose 2 meter or 9 meter unterminated cable, 4-pin M12 or 4-pin M8 QD connectors (either integralor with 150 mm pigtail)•Wide operating range of –20 °C to +60 °C (–4 °F to +140 °F)•Temperature compensation•Configurable for normally open or normally closed operation•Fast response time (15 milliseconds)WARNING:•Do not use this device for personnel protection•Using this device for personnel protection could result in serious injury or death.•This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.ModelsOnly standard 2 m (6.5 ft) cable models are listed. For 9 m (30 ft) shielded cable, add suffix “W/30” to the model number (e.g., QS18UNA W/30). A model with a QD connector requires a mating cordset. For QD models:•To order the 4-pin integral M12 QD model, add the suffix Q8 (for example, QS18UNAQ8).•To order the 150 mm (6 in) cable with a 4-pin M12 QD model, add the suffix Q5 (for example, QS18UNAQ5).•To order the 4-pin integral M8 QD model, add the suffix Q7 (for example, QS18UNAQ7).•To order the 150 mm (6 in) cable with a 4-pin M8 QD model, add the suffix Q (for example, QS18UNAQ).Principles of OperationUltrasonic sensors emit one or multiple pulses of ultrasonic energy, which travel through the air at the speed of sound. A portion of this energy reflects off the target and travels back to the sensor. The sensor measures the total time required for the energy to reach the target and return to the sensor. The distance to the object is then calculated using the following formula: D = ct ÷ 2D = distance from the sensor to the targetc = speed of sound in airt = transit time for the ultrasonic pulseTo improve accuracy, an ultrasonic sensor may average the results of several pulses before outputting a new value.Temperature EffectsThe speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For most ultrasonic applications, the composition and pressure of the gas are relatively fixed, while the temperature may fluctuate.In air, the speed of sound varies with temperature according to the following approximation:In metric units:Cm/s = 20√273 + T CIn English units:ft/s = 49√460 + T FCC m/s = speed of sound in meters per second C ft/s = speed of sound in feet per secondT C = temperature in °C T F = temperature in °FTemperature CompensationChanges in air temperature affect the speed of sound, which in turn affects the distance reading measured by the sensor. An increase in air temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits farther away from the sensor. This shift is approximately 3.5% of the limit distance for a 20° C change in temperature.WORLD-BEAM QS18U Ultrasonic SensorsOriginal Document119287 Rev. K28 July 2021119287The QS18U series ultrasonic sensors are temperature compensated This reduces the error due to temperature by about 90%. The sensor will maintain its window limits to within 1.8% over the -20° to +60° C (−4° to +140° F) range.Note:•Exposure to direct sunlight can affect the sensor’s ability to accurately compensate for changes in temperature.•If the sensor is measuring across a temperature gradient, the compensation will be less effective.•The temperature warmup drift upon power-up is less than 7% of the sensing distance. After 5 minutes, the apparent switchpoint will be within 0.6% of the actual position. After 25 minutes, the sensing position will be stable.Sensor ProgrammingFigure 1. Sensor Features(IP67 models only)Yellow/Red TEACH/Output Indicator LEDTwo TEACH methods may be used to program the sensor:•Teach individual minimum and maximum limits, or•Use Auto-Window feature to center a sensing window around the taught position The sensor may be programmed either via its push button, or via a remote switch. Remote programming also may be used to disable the push button, preventing unauthorized personnel from adjusting the programming settings. To access this feature, connect the white wire of the sensor to 0V dc, with a remote programming switch between the sensor and the voltage.Programming is accomplished by following the sequence of input pulses (see programming procedures ). The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are defined as “T: 0.04 seconds < T < 0.8 seconds ."Figure 2.

The distance to the object is then calculated using the following formula: D = ct ÷ 2D = distance from the sensor to the targetc = speed of sound in airt = transit time for the ultrasonic pulseTo improve accuracy, an ultrasonic sensor may average the results of several pulses before outputting a new value.Temperature EffectsThe speed of sound is dependent upon the composition, pressure and temperature of the gas in which it is traveling. For most ultrasonic applications, the composition and pressure of the gas are relatively fixed, while the temperature may fluctuate.In air, the speed of sound varies with temperature according to the following approximation:In metric units:Cm/s = 20√273 + T C In English units:ft/s = 49√460 + T FCC m/s = speed of sound in meters per second C ft/s = speed of sound in feet per second T C = temperature in °CT F = temperature in °FTemperature CompensationChanges in air temperature affect the speed of sound, which in turn affects the distance reading measured by the sensor. An increase in air temperature shifts both sensing window limits closer to the sensor. Conversely, a decrease in air temperature shifts both limits farther away from the sensor. This shift is approximately 3.5% of the limit distance for a 20° C change in temperature.The S18U series ultrasonic sensors are temperature compensated. This reduces the error due to temperature by about 90%. The sensor will maintain its window limits to within 1.8% over the -20° to +60° C (−4° to +140° F) range.NOTE:•Exposure to direct sunlight can affect the sensor’s ability to accurately compensate for changes intemperature.•If the sensor is measuring across a temperature gradient, the compensation will be less effective.•The temperature warmup drift upon power-up is less than 1.7% of the sensing distance.After 10 minutes, theapparent distance will be within 0.3% of the actual position. After 25 minutes, the sensing position will be stable.Wiring DiagramsFigure 5. Cabled ModelsFigure 6.

超声波气泡检测传感器
超声波气泡检测传感器一、摘要介绍了一种广泛应用于血液净化设备中的超声波气泡监测传感器，此传感器在血液净化过程中，当血液在体外循环时，对整个回路系统起监控作用；简述超声波及其检测电路工作原理，并对其结构特性作了说明；对传感器在血液净化技术中的临床应用原理、工作条件和安全监测功能进行了深入的分析，并给出了详细的电路原理图。
结合设备临床操作与应用情况，提出了自适应算法来自动确立报警阈值，克服了环境温度、现场操作等差异，有效地避免了误报和漏报现象。
二、产品介绍1、超声波空气传感器的设计原理超声波是在脉冲电压激励下，由换能晶片发生振动而产生的一种波，其振动频率大于20 kHz以上，每秒的振动次数(频率)很高，超出了人耳听觉的上限(20kHz)。
超声和可闻声都是一种机械振动，通常以纵波的方式在弹性介质内传播，是一种能量的传播形式。
超声波具有频率高，波长短，绕射现象小，在一定距离内沿直线传播具有良好的束射性和方向性等特点。
并且超声波能在空气、水、液体及金属等固体中传播。
超声波在不同的传播介质中的声阻抗是不同的,同一种超声波传感器一般不能用于不同的介质。
例如,空气与水和钢的声阻抗比分别为1∶3.4×103、1∶1×105,它们的声阻抗差别非常大。
因此利用超声波的这一特性,设计了一种监测空气气泡的传感器，此传感器用于血液体外循环时，检测液体管路中的空气气泡。
超声波传感器对被测物的检测通常有3种方式（如图1 所示）,超声波传感器可发射、接收。
考虑到医疗设备中液体(如血液等)流通管路的形状结构一般为圆柱形,选用透过方式较好。
这种方式下,发射的超声波将直线传播到接收端换能器。
气泡监测传感器的构造如图2。
图2中,发射端与接收端的超声波换能器芯片封装在一个内空为圆柱形的壳体中,为保证接收端接收效率更高,其发射面与接收面中心应尽量保持在一个水平面上。
此外,还要尽可能减小传感器靠近管壁的壳体与管路管壁间的空气隙。

(15)T ake note of safety instructions for Ex applicationsPlease note the Ex specific safety information that you can find at and that comes with each instrument. In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. The sen -sors must only be operated on intrinsically safe circuits. The permissible electrical values are stated in the certificate.Measuring principle29023-E N -1603121 Measuring principleMeasuring principleVEGASON emits short ultrasonic pulses in the direction of the measured medium. These pulses are reflected by the product surface and received back again by the sensor. The measuring instrument calculates the level from the running time of the sound wave and the entered vessel height. The non-contact measuring principle is unaffected by product properties and allows setup and commissioning even without medium.AdvantagesThe compact design enables a simple installation of the sensor. Since the product properties do not influence the level measurement, setup can also be carried out without medium. The inexpensive, non-contact measuring principle allows wear and maintenance free operation.Input variableThe reference plane for the measurement is the lower edge of thetransducer. All statements concerning the measuring range as well as the internal signal processing refer to this.With all instruments a minimum distance from the lower edge of theflange - the so-called dead band, in which measurement is not possible - must be maintained. Y ou can find the exact value of the dead band in the operating instructions manual of the respective instrument.Fig. 1: Data of the input variable with VEGASON 631 Reference plane2 Max. measuring range3 Dead zone4Utilisable measuring range29023-EN-1603122 T ype overviewVEGASON 61VEGASON 62VEGASON 63ApplicationsContinuous level measurement of liquids or bulk solids in storage vessels or open basinsMax. measuring range In liquids: 5 m (16.4 ft)In bulk solids: 2 m (6.562 ft)In liquids: 8 m (26.25 ft)In bulk solids: 3.5 m (11.48 ft)In liquids: 15 m (49.21 ft)In bulk solids: 7 m (22.97 ft)Material transducer PVDF PVDF UP/316 Ti Material, process fitting PVDFPVDFUPProcess temperature -40 … +80 °C (-40 … +176 °F)-40 … +80 °C (-40 … +176 °F)-40 … +80 °C (-40 … +176 °F)Process pressure -0.2 … +2 bar/-20 … +200 kPa (-2.9 … +29 psig)-0.2 … +2 bar/-20 … +200 kPa (-2.9 … +29 psig)-0.2 … +1 bar/-20 … +100 kPa (-2.9 … +14.5 psig)Deviation ±4 mm or < 0.2 %±4 mm or < 0.2 %±6 mm or < 0.2 %Signal output• 4 … 20 mA/HART - two-wire • 4 … 20 mA/HART - four-wire • Profibus PA• Foundation Fieldbus • 4 … 20 mA/HART - two-wire • 4 … 20 mA/HART - four-wire • Profibus PA• Foundation Fieldbus • 4 … 20 mA/HART - two-wire • 4 … 20 mA/HART - four-wire • Profibus PA• Foundation Fieldbus Indication/Adjustment• PLICSCOM • PACT ware • VEGADIS 81• VEGADIS 82• PLICSCOM • PACT ware • VEGADIS 81• VEGADIS 82• PLICSCOM • PACT ware • VEGADIS 81• VEGADIS 82Approvals• ATEX • IEC• Shipbuilding • FM • CSA•EAC (Gost)• ATEX • IEC• Shipbuilding • FM •CSA•EAC (Gost)•ShipbuildingInstrument selection29023-E N -1603123 Instrument selectionApplication areasThe ultrasonic sensors of the VEGASON series are suitable for non-con -tact level measurement of liquids and bulks solids in simple applications with stable measurement conditions.VEGASON 61VEGASON 61 is an ultrasonic sensor for continuous level measurement of liquids or bulk solids. T ypical applications are the measurement of liquids in storage vessels or open basins. The sensor is also suitable for the detection of bulk solids in small vessels or open containers.VEGASON 62VEGASON 62 is an ultrasonic sensor for continuous level measurement of liquids or bulk solids. T ypical applications are the measurement of liq -uids in storage vessels or open basins. The sensor is also suitable for the detection of bulk solids in small vessels or silos. Application areas can be found in all industries.VEGASON 63VEGASON 63 is an ultrasonic sensor for continuous level measure -ment of liquids or bulk solids. T ypical applications are the measurement of liquids in storage vessels or open basins. The sensor is also suitable for continuous level measurement of bulk solids in small vessels up to average-size vessels.ApplicationsLevel measurement in vesselsFor level measurement in vessels with conical bottom it can be advanta-geous to mount the sensor in the center of the vessel, as measurement isthen possible down to the lowest point of the vessel bottom.Fig. 5: Level measurement in vessels with conical bottomLevel measurement in a standpipeWhen used in a standpipe (surge or bypass tube), the influence of vessel installations, foam generation and turbulence is excluded. Standpipes must reach down to the requested min. level because measurement is only possible within the tube.Fig. 6: Standpipe in the tank 1Vent hole: ø 5 … 10 mm (0.197 … 0.394 in)Level measurement in basinsT o reduce the min. distance to the medium, you can also mount the VEGASON with a beam deflector. By doing this, it is possible to fill the vessel nearly to maximum. Such an arrangement is suitable primarily for open vessels such as e.g. overflow basins.29023-EN-1603124 Selection criteriaVEGASON 61VEGASON 62VEGASON 63VesselSmall vessels ●●●Average-size vessels –●●Open basins●●●ProcessFlow measurement ●●–Aggressive products●●–InstallationThreaded fittings ●●–Flange connections ●●●Hygienic fittings ●●–Mounting strap––●T ransducerMeasurement in a bypass tube or surge pipe ●●●Suitability for industry-specific applicationsOffshore ●●●Shipbuilding ●●●Water, waste water●●●Housing overview29023-E N -1603125 Housing overviewPlastic PBTProtection rating IP 66/IP 67IP 66/IP 67VersionSingle chamber Double chamber Application areaIndustrial environmentIndustrial environmentAluminiumProtection rating IP 66/IP 67, IP 66/IP 68 (1 bar)IP 66/IP 67, IP 66/IP 68 (1 bar)VersionSingle chamberDouble chamberApplication areaIndustrial environment with increased me-chanical stressIndustrial environment with increased me-chanical stressStainless steel 316LProtection rating IP 66/IP 67IP 66/IP 67, IP 66/IP 68 (1 bar)IP 66/IP 67, IP 66/IP 68 (1 bar)VersionSingle chamber, electropolishedSingle chamber, precision castingDouble chamber, precision casting Application areaAggressive environment, food processing, pharmaceuticalAggressive environment, extreme mechani -cal stressAggressive environment, extreme mechani -cal stress29023-EN-1603126 MountingMounting examplesThe following illustrations show mounting examples and measurement setups.Waste water tankFig. 15: Level measurement in the waste water tank with VEGASON 61Due to the solid components and the varying density of the tankcontents, non-contact level measurement with ultrasonics is the most suitable method here.

仪器主要开关旋钮的作用及其调整1．工作方式选择旋钮工作方式选择旋钮的作用是选择探测方式，即“双探”或“单探”方式。
当开关置于位置“””时，为单探头12发”位置的发射强度是可变的，旋钮置于该位置时，可用发2、发射强度旋钮发射强度旋钮的作作用是改变仪器的发射脉冲功率从而改变仪器的发射强度。
增大发射强度时，可提高仪器的灵敏度，但脉冲变宽，分辨里变差。
因此，在探伤灵敏度能满足的情况下，发射强度旋钮应尽量放在较低的位置。
3、衰减器衰减器的作用是调节探伤灵敏度和测量回波振幅。
调节灵敏度时，衰减读数大，灵敏度低。
衰减读数小，灵敏度高。
测量回波振幅时，衰减读数大，回波幅度高，衰减读数小，回波幅度低。
一般探伤仪衰减器分粗调和细条两种，粗调每档10dB或20 dB，细调每档2 dB或1 dB，总衰减量80 dB左右。
4、增益旋钮增益旋钮也程增益细调旋钮，其作用是改变接收放大器的放大倍数，进而连续改变探伤仪的灵敏度，使用时将反射波高度精确的调节到某一指定高度，仪器灵敏度确定以后，探伤过程中一般不在调整增益旋钮。
5、抑制旋钮抑制的作用是抑制荧光屏上幅度较低或认为不必要的杂乱反射波，使之不予显示，从而使荧光屏显示的波形清晰。
值得注意的是使用抑制时，仪器垂直线性和动态范围将被改变。
抑制作用越大，仪器动态范围越小，从而在实际探伤中有容易漏掉小缺陷的危害。
因此，除非十分必要时一般不使用抑制。
6、深度范围旋钮深度范围旋钮也称深度粗调旋钮,其作用是粗调荧光屏扫描线所代表的探测范围。
调节深度范围旋钮，可较大幅度的改变时间扫描线的扫描速度。
从而使荧光屏上回波间距大幅度的压缩或扩展粗挑选钮一般都分为若干档级，探伤时应视被探工件厚度选择合适的档级。

TI00490C/07/EN/03.1271202237Technical InformationTurbimax CUS71DUltrasonic interface sensorImmersion sensor for interface measurementApplicationIn many instances in process engineering, suspensions are separated into their solid and liquid components bysedimentation. To operate this process economically and efficiently in practice, it is indispensable to monitor theseparation and transition zones of the clarification and settling phases continously.Turbimax CUS71D is a sensor for many applications of the interface measurement•Wastewater treatment: primary clarifier, sludge thickener, secondary clarifier•Water purification: settling basin after flocculant dosage, filter media expansion monitoring to optimize backwash operations, sludge height in contact sludge process •Chemical industry: static separation process Your benefits•Two different sensor models allow optimal adaption to the measurement task.•Simple commissioning thanks to predefined calculation models.•Intelligent sensor - all characteristics and calibration values are stored in the sensor.Turbimax CUS71DFunction and system designMeasuring principle A piezoelectric crystal is integrated in a flat cylindrical plastic housing. When the crystal is excited by anelectrical voltage, it generates a sonar signal. The ultrasonic waves are transmitted at a frequency of 657 kHzat an angle of 6° to scan the separation zones.The parameter measured is the time it takes for the transmitted ultrasonic signal to reach the solid particles inthe separation zone and return to the receiver.A sensor version with wiper avoids film formation at the sensor membrane.Function The speed of the sound varies according to the physical properties of the measuring medium and is affected bytemperature and air pressure. The liquid zones and solids content of the medium also vary.To obtain precise measurement results, it is therefore vital to adapt system variables to the process, e. g.pulselength and the speed of the sound.The CM44x offers the following possibilities for signal evaluation:•Mask out regions where the separation zone is not expected.•Evaluate received signal strengths differently.•Select leading or trailing signal edges in the evaluation.•Amplify sensor signals at different rates, e. g. for floating sludge.•Define a region (gate) above and below the separation zone. Signal evaluation only takes place in the definedregion. The gate wanders with the separation zone. This makes smoothing algorithms unnecessary. Sensor monitoring The optical signals are continuously monitored und checked for plausibility.Discrepancies are reported via error messages by the transmitter.The sensor check system of the Liquiline CM44x reports the following failure conditions:•Implausible high or low measuring values•Disturbed controlling due to erroneous measuring valuesSensor connection•Liquiline CM442 transmitter:You can connect only one ultrasonic interface sensor. In this case, the 2nd channel cannot be used toconnect any other sensor.•Liquiline CM444 and CM448 transmitters:If you connect one or more ultrasonic interface sensors, you can connect a maximum of four sensors (nomatter which type of sensor, ultrasonic or others).Transmitter Sensor CUS71D Other sensorsCM442 (max. 2 channels)10CM444 (max. 4 channels)any combination (max. 4 sensors)CM448 (max. 8 channels)any combination (max. 4 sensors)2Endress+HauserTurbimax CUS71DMeasuring system A complete measuring system comprises:•Ultrasonic sensor Turbimax CUS71D•Multi-channel transmitter Liquiline CM44xand optional:•Weather protection roof CYY101•Holder system Flexdip CYH112•Fixed or rotatable immersion pipe Flexdip CYA112Ultrasonic sensor with holder system and multi-channel transmitter1Holder system Flexdip CYH1124Assembly Flexdip CYA1122Multi-channel transmitter Liquiline CM44x5Ultrasonic sensor Turbimax CUS71D3Weather protection roofEndress+Hauser3Turbimax CUS71D4Endress+HauserMeasuring system with pendulum adapterMeasuring system with pendulum adapterThe PVC sensor protector protects the ultrasonic sensor from getting damaged by the surface skimmer.1Cross clamp of holder system Flexdip CYH112 3Assembly Flexdip CYA112 with CUS71D 2Pendulum adapter of holder system Flexdip CYH1124PVC sensor protectorTurbimax CUS71DEndress+Hauser 5InputMeasuring variablesMeasuring rangePower supplyThe sensor is connected to the transmitter as follows:Sensor connectionThe maximum cable length is 100 m (328 ft).To extend the sensor cable, the following accessories are recommended:•Measuring cable CYK11 with ferrules and •Junction box "cable / cable"You can connect only 1 sensor to the transmitter Liquiline CM442.You can connect up to 4 sensors to the transmitters Liquiline CM444 and CM448.Standard sensor Interface Sensor with wiperInterfaceStandard sensor 0.3 to 10.0 m (1.0 to 32 ft)Sensor with wiper0.3 to 10.0 m (1.0 to 32 ft)Turbimax CUS71DPerformance characteristicsMaximum measured error 35 mm at 3.0 mMeasured value resolution 3 mm at 3.0 mMeasurement interval AdjustableCalibration The sensor is factory calibrated delivered.The "speed of sound" is adjustable and preprogrammed for the application "water".6Endress+HauserTurbimax CUS71DInstallation conditionsInstallation instructions Basin configurationBasin configurationA SensorB Minimum distance of sensor to basin wall = 45 cm (1.48 ft.)C Reference point e.g. water surfaceD Zero pointE Basin depthF Opening angle of ultrasonic cone, 6°Installation instructionsLook at the construction drawing of the basin for a suitable position for the sensor. In doing so, you must takethe following factors into account:•The minimum distance between the basin wall and the sensor is 45 cm (1.48 ft.) (sensor emits ultrasoundin conical form).•There should not be any basin wall protrusions or piping in the measuring range below the sensor. Scrapersthat are only temporarily in this area are permitted.•Do not install the sensor in zones in which air bubbles, turbulence, high levels of turbid material orsuspended matter or foam formation occur (e.g. inlet).•Using an immersion tube, install the sensor 20 cm ( 0.66 ft.) beneath the surface of the water.•The transmitter may not be installed in a second enclosure (heat accumulation).•If possible, do not install the transmitter near high voltage sources. In addition, also avoid sources of magneticfields, e.g. large transformers or frequency converters.•The system can only detect a separation zone if there is a clear transition between the zones. Uncleartransition from the liquid to the solid phase cannot be detected.Endress+Hauser7Turbimax CUS71DCircular ClarifierBasin configuration in circular clarifierA View from topB Cross section1Surface skimmer11Sensor2Walk way12Hand rail3Sensor mounting13Surface skimmer4Bottom rake14Bottom rake5Rake directionEnvironmentStorage temperature-20 to 50 °C (-4 to 122 °F)Ingress protection IP 68 (test conditions: 1 m (3.3 ft) water column during 60 days, 1 mol/l KCl)ProcessProcess temperature 1 to 50 °C (34 to 122 °F)Process pressure0.0 to 6 bar (0 to 87 psi) absolute8Endress+HauserTurbimax CUS71DEndress+Hauser 9Mechanical constructionDimensionsWeightMaterialsProcess connections G1 and NPT ¾''Dimensions of standard sensorDimensions of sensor with wiperStandard sensor 1.02 kg (2.25 lb)Sensor with wiper1.25 kg (2.75 lb)Sensor ABS and epoxy plastic WiperRubberTurbimax CUS71D10Endress+HauserCertificates and approvalsEMC compatabilityInterference emission and interference immunity complies with EN 61326: 2005, Namur NE 21:2007Ordering informationSelectionOrder codeTo get to the product page enter the following address into your browser:/cus71d 1.2.Click "Configure this product".3.The configurator opens in a separate window.

超声波仪器探头性能指标及其测试方法
超声波仪器、探头主要组合的性能测定一、超声波探伤仪主要性能测试方法1、电噪声电平（%）仪器灵敏度置最大，发射置强，抑制置零或关，增益置最大，衰减器置“0”，深度粗调、深度微调置最大。
读取时基线噪声平均值，用百分数表示。
2、灵敏度余量（dB）a)使用2.5MHz、Φ20直探头和CS－1－5或DB--PZ20—2型标准试块。
b)连接探头并将仪器灵敏度置最大，发射置强，抑制置零或关，增益置最大。
若此时仪器和探头的噪声电平(不含始脉冲处的多次声反射)高于满辐的10％，则调节衰减或增益，使噪音电平等于满辐度的10％记下此时衰减器的读数S0。
图1 直探头相对灵敏度(灵敏度余量)测量c)将探头置于试块端面上探测200mm处的i2平底孔，如图17所示。
移动探头使中Φ2平底孔反射波辐最高，并用衰减器将它调至满辐度的50％，记下此时衰减器的微S l，则该探头及仪器的探伤灵敏度余量S为：S=S1--S0(dB)3、垂直线性误差测量（%）(1)连接探头并在试块上探测任一反射波(一般声程大于50mm)作为参照波，如图2所示。
调节探伤仪灵敏度，使参照波的辐度恰为垂直刻度的100％，且衰减器至少有30dB的余量。
测试时允许使用探头压块。
图2 垂直线性误差测量(2)用衰减器降低参照波的辐度，并依次记下每衰减2dB时参照波辐度的读数，直至衰减26dB以上。
然后将反射波辐度实测值与表l中的理论值相比较，取最大正偏差d(+)与最大负偏差d(-)，则垂直线性误差△d用式(1)计算：△d=｜d(+)｜+｜d(-)｜ (1)(3)在工作频率范围内，改用不同频率的探头，重复(1)和(2)的测试。
4、动态范围的测量（dB）(1)连接探头并在试块上探测任一反射波(一般声程大于50mm)作为参照波。
(2)调节衰减器降低参照波，并读取参照波辐度自垂直刻度的100％下降至刚能辨认之最小值(一般约为3～5％)时衰减器的调节量，此调节量则定为该探伤仪在给定频率下的动态范围。
超声波探头主要技术参数
超声波探头主要技术参数本页仅作为文档封面，使用时可以删除This document is for reference only-rar21year.March一、超声波探头超声波探头又称超声波换能器，它是采用进口镀膜晶片，适用于空气介质中测距、物位检测的电声转换器件。
由于换能器的聚焦件采用了多层阻抗匹配、背衬、压电元件频率误差小，具有良好的时间稳定性和温度稳定性、无退极化现象，通带特性好，芯片与声传输器件统一计算基波谐振频率。
独创的背衬材料配方，具有良好的振动特性，使换能器有很大的频带宽度，发射和接收灵敏度高，以及较小的脉冲－回波持续时间，获得了最大的等效机电耦合系数。
二、探头主要技术参数◇中心谐振频率：40kHz±2kHz◇静态电容量：3300P±300P◇谐振阻抗：120Ω±20Ω◇频带宽度（－3dB）：Δf－3dB≥2kHz◇工作电压：300～500VP－P◇极限电压≤1000VP－P◇发射波束角：6O度◇工作温度：-40～+80℃◇防护等级：IP65三、模块性能1：使用电压：DC5V；2：静态电流：小于2mA；3：输出信号：电平信号，高电平5V，低电平为0V；5：感应角度：60度；6：探测距离：0.01 – 5.00米；7:高精度：可达1mm四、脚引接线说明（脚引定义的观察方向：探头向下，引脚向内，从左到右）1、GND和VCC是电源供电引脚，模块正5V供电；2、IN脚是模块的信号输入脚，用户从此脚输入控制信号，驱动模块工作，控制信号可以从单片机的IO口输出方波信号；3、OUT脚是模块接收到超声波后的返回信号输出脚，此引脚步在模块上电后输出高电平，当用户从输入脚发出驱动信号后，如果模块接收到返回超声波，OUT引脚即被拉低，输出低电平；4、保留引脚用于功能扩展；五、工作原理用户通过从IN脚输入40KH的方波信号，即用户从单片机的IO口连续发出高低电平，产生方波，方波的个数一般为10个左右，发出后用户启动定时器，开始计时，此时，超声波发射头开始发出超声波，当发出的超声波被前方的障碍物返射回来，返射回来的超声波被接收探头接收到，此时，模块的OUT引脚会产生一个从高电平到低电平的跳变，此时，用户要停止计时，用户通过计时的时间，根据以下公式计算测量距离：测量距离= (时间*声速( 340M/S ) ) / 2六、注意事项1、超声波发射头向外发射60度角的超声束，因此，在探头与被测物体之间不能有其他障碍物。
