智能传感器的结构特点与应用领域

智能传感器的结构特点与应用领域

智能传感器的结构特点与应用领域智能传感器究竟是什么随着测控系统自动化、智能化的发展,传统的传感器已经不能满足一定的数据处理能力以及自检、自校、自补偿的功能,智能传感器和多功能传感器的研发和应用已经走向市场。

定义智能传感器(intelligent sensor)是具有信息处理功能的传感器。

智能传感器带有微处理机,具有采集、处理、交换信息的能力,是传感器集成化与微处理机相结合的产物。

与一般传感器相比,智能传感器具有以下三个优点:通过软件技术可实现高精度的信息采集,而且成本低;具有一定的编程自动化能力;功能多样化。

一个良好的‘智能传感器’是由微处理器驱动的传感器与仪表套装,并且具有通信与板载诊断等功能。

智能传感器能将检测到的各种物理量储存起来,并按照指令处理这些数据,从而创造出新数据。

智能传感器之间能进行信息交流,并能自我决定应该传送的数据,舍弃异常数据,完成分析和统计计算等。

智能传感器系统是一门现代综合技术,是当今世界正在迅速发展的高科技新技术,但还没有形成规范化的定义。

早期,人们简单、机械地强调在工艺上将传感器与微处理器两者紧密结合,认为“传感器的敏感元件及其信号调理电路与微处理器集成在一块芯片上就是智能传感器”。

关于智能传感器的中、英文称谓,尚未有统一的说法。

John Brignell和Nell White认为“Intelligent Sensor”是英国人对智能传感器的称谓,而“Smart Sensor”是美国人对智能传感器的俗称。

而Johan H.Huijsing在“Integrated Smart Sensor”一文中按集成化程度的不同,分别称为“Smart Sensor”、“Integrated Smart Sensor”。

对“Smart Sensor”的中文译名有译为“灵巧传感器”的,也有译为“智能传感器”的。

《智能传感器系统》书上的定义:“传感器与微处理器赋予智能的结合,兼有信息检测与。

unisense电极原理

unisense电极原理

unisense电极原理
Unisense电极的原理是氧微电极原理,即克拉克型氧电极通过测量氧分压来获得与之对应的电信号。

氧气通过微电极硅酮膜扩散进电极产生电流,消耗不掉的氧气会被保护阴极消耗掉。

皮安级电流传输到主机被放大,然后传输至电脑软件读数。

此外,UNISENSE电极有很高的精度,能无损测量多种生物和环境类样品。

除了氧微电极原理外,Unisense电极还采用了微孔技术,这种技术使得电极在测量时能够更好地适应环境,并且可以有效地防止堵塞和污染。

此外,Unisense电极还具有高灵敏度、低噪音、长期稳定等特点,使得它能够在各种环境下进行精确的测量。

另外,Unisense电极的校准也非常重要,它可以通过标准溶液对电极进行校准,以保证测量的准确性和可靠性。

同时,由于Unisense电极具有很高的精度和稳定性,因此它不仅可以用于科学研究,还可以用于工业生产、环境监测等领域。

Unisense电极是一种高精度、高灵敏度、低噪音、长期稳定的氧微电极,它能够适应各种环境,并且可以进行精确的测量。

For a complete list of sensors sizes and types please go towww .unisense .com .The standard hydrogen sensor type, the H2-type, is for use in environments where H2S is not expected to occur . The H2S insensitive type, the H2-X-type, has an H2S trap in front of the H2 sensing part, allowing the sensor to be used in H2S containing environments (see “5:3 Interference”) .The Unisense hydrogen microsensor is designed for research applications within physiology, biotechnology, environmental sciences, and related areas .With the minute tip size, excellent response time, and good sensitivity the Unisense hydrogen sensor facilitates reliable and fast measurements with a high spatial resolution .The H2-X sensor has a slightly longer response time than the corresponding H2 sensor .The Unisense hydrogen microsensor is a miniaturizedClark-type hydrogen sensor with an internal reference electrode and a sensing anode . The sensor must be connected to a high-sensitivity picoammeter where the anode is polarized against the internal reference . Driven by the external partial pressure, hydrogen from the environment will pass through the sensor tip membrane and will be oxidized at the platinum anode surface . The picoammeter converts the resulting oxidation current to a signal .Schematic view of a hydrogen sensorwith a LEMO plug.IMPORTANT Unisense sensorsare neitherintended nor approved for use inhumans84: GETTING STARTEDThe H2-type and H2-X-type sensors are used in the same way . Only the sensitivity to H2S and the response time differ between the two types of hydrogen sensors .4:1 u npacking a new sensorWhen receiving a new microsensor remove the shock-absorbing grey plastic net .4:2 p olarizationThe signal from the hydrogen sensor is generated in picoampere . Therefore the hydrogen sensor must be connected to a polarizing picoammeter (e .g . a UniAmp series amplifier) .The anode of the hydrogen sensors should be polarized at +100 mV relative to the cathode . This happens automatically on the Unisense UniAmp series instruments . On the Unisense Multimeter, Monometer and PA-2000 instruments this must be set manually . Please consult the relevant the instrument manual for how to adjust polarization . If you are using a PA2000, please check the polarization voltage before connecting the sensor, since incorrect polarization may destroy the sensor .4:3 c onnecting tHe microsensorInsert the connector into a pA input terminal on the amplifier . The connector contains connections for both internal reference electrode and sensing anode .WARNING Do not remove the seal and protectiveplastic tube before these stepsand calibrationare succesfullycompleted.WARNINGIncorrect polarization may destroy the sensorNOTE The conversionof sensor signal in pA to amplifiersignal in mV is controlled by thePre-Amp Range (mV/pA) setting on the amplifer (notPA-2000)94:4 p re-polarizationJust after connecting the sensor, the signal will be very high and unstable then drop rapidly over the first few minutes . After that the signal will drop slowly for up to 1 hour . Therefore, a periodof polarization is necessary before you can use the sensor . This is called the pre-polarization period .The signal should stabilize at 0-10 picoampere (on the PA2000, the sign will be negative since sensor is positively polarized) forzero hydrogen concentration, depending on the specific sensor .If the sensor is new or has not been operated for several days, it must be polarized for at least 1 hour before it can be calibrated and used . After shorter periods without polarization, the sensor should be polarized until it has exhibited a stable signal for 10 minutes .The signal depends on the specific sensor type (see the value in the specifications that came with the sensor) .If the signal does not stabilize or is too high or too low, refer to the ‘Trouble-shooting’ section of this manual .4:5 c alibrationThe calibration procedure is the same for the H2 and H2-X sensors . Calibration must be performed after the sensor signal has stabilized during pre-polarization .z ero hydrogen readingPlace/keep the sensor tip in water and read the signal . This signal is your calibration value for zero hydrogen conditions .h ydrogen readingThe hydrogen sensor responds linearly and consequently atwo-point calibration is sufficient . Prepare water with a defined hydrogen concentration, which is slightly above the maximum expected concentration to be measured . A defined hydrogen concentration can be obtained by 2 different procedures:IMPORTANT Hydrogen sensorsare sensitive to temperature andsalinity,IMPORTANT Calibration must be performed after pre-polarization when the sensorsignal hasstabilized.Always usea calibration solution with the same temperature and salinity as the sample solution.101 . Use a gas mixture controller to obtain a defined mixture ofhydrogen and hydrogen free inert gas from a gas tank (e .g .N2) as bulk carrier gas . For instance, to obtain a hydrogenconcentration of 40,25 µM in the calibration chamber at 20°C, bubble the water in the calibration chamber vigorously witha gas mixture containing a 95 % N2 and 5 % H2 . The hydrogenpartial pressure is in this case 0 .05 atm, and the Solubility is 805 μmol/L/atm . Multiplying the solubility with the partialpressure results in the concentration: 805 µmol/L/atm * 0,05 atm = 40,25 µM .See Table 1 for more values of the solubility, or use the H2calculator in the Unisense SensorTrace Suite software .Start the software, click “Tools” and select “H2 calculator” . .For a Unisense CAL300 calibration chamber,5 minutes of bubbling at a rate of 5 l perminute is sufficient time to achieve 99 % of theconcentration . If the equipment (gas mixturecontroller) is available, this method can beconvenient, as you can switch between differentconstant hydrogen conditions without changingthe water . Use the solubility table (Table 1),or the H2calculator in the SensorTrace software to find the correct mixture at temperatures other than 20°C .To obtain correct concentrations, the headspace above thewater in the calibration chamber must be closed except fora hole only slightly larger than the microsensor shaft . Thiseffectively prevents ambient air from entering the vessel . We recommend the CAL300 Calibration Chamber for calibrations .2 . Add a defined volume of hydrogen-saturated water to adefined volume of water in a calibration chamber . For instance,1 ml of H2saturated water contains 0,805 µmol at 20°C (see Table 1), or the H2 calculator in the SensorTrace software,and to obtain water with a hydrogen concentration of 10 µM,3 .08 ml hydrogen-saturated water should be added to a totalvolume of 246,9 ml hydrogen free water in the calibrationWARNING Vigorous bubbling water with anygas may cause the water to coolconsiderably.Monitor the temperature tofind a suitablebubbling rate,which does notcool the watersignificantly.Calibration chamber CAL300chamber . After the addition of hydrogen-saturated water tothe calibration chamber mix it thoroughly by moving thesensor in its protection tube up and down for a few seconds and read the signal when it is stable . Do not stir bubbles into the water or mix by bubbling, as this will remove hydrogenfrom the water . A magnetic stirrer is not recommended asa mixing tool as a magnetic stirring can introduce electricalnoise to the signal . The hydrogen in the water will slowlyescape to the atmosphere and the concentration can only be considered constant for a few minutes .Hydrogen sensors respond linearly in the range of 0 to 100 %) and signals can be hydrogen (Low Range sensor from 0 - 10% H2linearly converted to partial pressure .Check and repeat calibration at appropriate intervals to ensure that all measurements can be converted to correct concentrations . When the sensor is new, the appropriate interval may be every2 hours; later it may be 24 hours . To minimize the need for calibrations, keep the sensor polarized between measurements, unless the time between measurements exceeds several days or unless the picoammeter batteries are running out . The membrane permeability of hydrogen microsensors changes with time, so a change in signal of up to 50 % may occur over months .If the sensor functions according to the criteria given in the delivery note, the seal and protective plastic tube can be carefully removed before making measurements.5: MEASUREMENTSThe H2-type sensor should be used in H2S free environments . If H2Sis expected to be present, the H2-X-type sensor should be used .Hydrogen sensors can be used for a wide variety of measurements(see our website for further information www .unisense .com) . Themost common use of hydrogen sensors is for making profiles ine .g . sediment or animal tissue where a high spatial resolution iswanted, or for hydrogen measurements in water samples .5:1 m ounting of tHe sensorsAlthough the Unisense microsensors are made of glass, the tipis flexible and can bend slightly around physical obstacles . Thesensor is thus rather sturdy in the longitudinal direction . However,large obstacles like stones or lateral movements of the sensorwhen the tip is in contact with a solid substrate may cause the tip Array to break .Furthermore, due to the small size of the microsensor tip andto the steepness of gradients in many environments, even adisplacement of the sensor tip of few microns may change itsenvironment .Therefore, we recommend that measurements should beperformed only in a stabilized set-up free of moving or vibratingdevices . We recommend the Unisense lab stand LS and theUnisense micromanipulator MM33 (MM33-2 or MMS) forMicromanipulator laboratory use . For in-situ use, we recommend our in situ stand(IS19) and a micromanipulator .5:2 e lectrical noiseThe signal of the microsensor is very small (10-13 to 10-10 ampere) .Although both the Unisense amplifiers and the UnisenseHydrogen microsensors are very resistant to electrical noise fromthe environment, electrical fields may interfere with the sensorsignal . Therefore, we recommend that unnecessary electrical/mechanical equipment is switched off and the sensor or wires arenot touched during measurements and signal recording .5:3 i nterferenceSulphide in the H2S form may interfere with the H2 measurements . The standard hydrogen sensor, the H2-type, is very sensitive to H2S and other reduced sulphur gases . It should, therefore, not be used in environments where H2S and other reduced sulphur gases are present . The H2-X sensor type is not sensitive to H2S up to 100 µM in solution or 1000 ppm H2S in gas . The H2S trap on the H2-X sensor works by removing protons from the H2S and the ionized formsof sulfide cannot pass through the silicone membrane into the H2 sensing part . Other sulphur gases where protons are less easily removed may still penetrate the silicone membrane . The H2-X sensor may, therefore, still be sensitive to other reduced sulphur gases than H2S . It is recommended to only expose the H2S-X sensor to H2S when needed, to maximize the lifetime of the H2S trap . The H2-X sensor may be made even more resistant to H2S .

详解村田制作所的MEMS传感器

详解村田制作所的MEMS传感器

详解村田制作所的MEMS传感器MEMS市场动向最近几年,使用了MEMS技术的半导体产品的需求及用途大幅增加。

MEMS是Micro Electro Mechanical Systems的缩写,硅电路板上由电路和机械可活动结构的三维构成。

使用此结构可实现将压力、温度、加速度这些物理量转换成电气信号的传感器,还可实现提供电气信号使可动结构体像机械一样运动的所谓执行器功能。

MEMS产品早在1980年就已经存在了,与使用了CMOS工艺的一般半导体相比,因为晶圆制成非常复杂,包装也很耗功夫,使得工程标准化和低成本变得十分困难,所以只应用于限定用途。

但是,最近确定了批量生产小型、高性能的MEMS产品的技术,除了汽车发动机控制、医疗器械、喷墨打印机这些常用用途,数码相机和智能手机这写随身携带的电子产品里也使用了很多的MEMS产品。

MEMS产品今后将持续每年10-15%的增长率,并可预测在2017年的时候将从现在的9200亿日元增长到17000亿日元。

(Yole Development公司预测)株式会社村田制作所在2012年1月份收购了芬兰的MEMS专业生产商VTI,VTI 改名为Murata Electronics Oy,成为了村田的一员。

Murata Electronics Oy 运用了独特的3D-MEMS(三维MEMS)技术向市场提供了高性能以及高可靠性的MEMS传感器。

村田制作所的MEMS传感器所有东西的运动都是X、Y、Z轴平行的运动和围绕轴的旋转运动,共表现为6个运动组合。

村田制作所制作了平行运动(平移加速度)传感的加速度传感器、旋转运动(角速度)传感的陀螺仪产品系列,应用于依赖高精度运动传感和高可靠性的特征的汽车、轮船的姿态控制、产业用装置的倾斜测定、医疗用途等等。

此次特辑将介绍生产具有高精度、高可靠性的传感器的独特技术的3D-MEMS和同时兼具高精度和高可靠性的加速度传感器以及陀螺仪的特征。

3D-MEMS技术使用了3D-MEMS技术的元件示例说明(图1)。

传感器的基本结构和工作原理

传感器的基本结构和工作原理

传感器的基本结构和工作原理今天咱们来唠唠传感器这个超有趣的小玩意儿。

传感器啊,就像是一个超级敏感的小机灵鬼。

你看它的基本结构,其实就像是一个特别的小团队。

它有一个敏感元件呢,这敏感元件就像是传感器的小鼻子,专门负责嗅探周围环境的变化。

比如说温度传感器里的敏感元件,就对温度的变化特别敏感,哪怕温度只是偷偷地上升或者下降了那么一丢丢,它都能察觉到。

就像你身边有个特别细心的小伙伴,你脸上刚露出一点不开心的表情,他就能发现。

然后呢,还有转换元件。

这个转换元件可厉害啦,它就像是一个翻译官。

敏感元件发现了环境的变化,但是这个变化的信号是那种很原始的,就像一种特别的“小暗号”。

转换元件就把这个暗号翻译成我们能理解的信号,可能是电信号之类的。

这就好比是外国友人跟你叽里咕噜说了一堆你听不懂的话,翻译官过来把那些话变成你能明白的内容。

传感器的工作原理啊,那可真是充满了奇妙的魔法。

比如说压力传感器,你可以想象它在一个汽车的轮胎里工作的场景。

汽车在路上跑的时候,轮胎里面的压力会有变化。

压力传感器的敏感元件就感受到这个压力的改变了,就像你躺在床垫上,床垫能感受到你的重量一样。

然后呢,这个敏感元件就把这个压力变化的信息传递给转换元件。

转换元件就把这个压力的变化转化成电信号,这个电信号就可以告诉汽车的控制系统,轮胎的压力是正常、过高还是过低。

如果压力过高或者过低,汽车仪表盘上就会亮起小灯来提醒驾驶员,就像轮胎在悄悄跟驾驶员说:“我的压力不太对啦,你得看看我哦。

”再说说光传感器吧。

在我们的手机里就有光传感器呢。

当你从明亮的地方走到黑暗的地方,光传感器的敏感元件就发现光线变弱了。

然后它就通知转换元件,转换元件就把这个光线变化的消息变成电信号,手机接收到这个信号后,就会自动调整屏幕的亮度。

就好像手机在贴心地说:“周围暗下来了,我得把屏幕调暗一点,这样你的眼睛就不会被刺到啦。

”传感器在我们的生活里无处不在。

在智能家居里,传感器就像是一个个小管家。

MEMS压力传感器结构及其工作原理

MEMS压力传感器结构及其工作原理

MEMS压力传感器结构及其工作原理
目前的MEMS压力传感器有硅压阻式压力传感器和硅电容式压力传感器,两者都是在硅片上生成的微机械电子传感器。

硅压阻式压力传感器是采用高精密半导体电阻应变片组成惠斯顿电桥作为力电变换测量电路的,具有较高的测量精度、较低的功耗和极低的成本。

惠斯顿电桥的压阻式传感器,如无压力变化,其输出为零,几乎不耗电。

MEMS硅压阻式压力传感器采用周边固定的圆形应力杯硅薄膜内壁,采用MEMS技术直接将四个高精密半导体应变片刻制在其表面应力最大处,组成惠斯顿测量电桥,作为力电变换测量电路,将压力这个物理量直接变换成电量,其测量精度能达0.01-0.03%FS。

硅压阻式压力传感器上下二层是玻璃体,中间是硅片,硅片中部做成一应力杯,其应力硅薄膜上部有一真空腔,使之成为一个典型的绝压压力传感器。

应力硅薄膜与真空腔接触这一面经光刻生成电阻应变片电桥电路。

当外面的压力经引压腔进入传感器应力杯中,应力硅薄膜会因受外力作用而微微向上鼓起,发生弹性变形,四个电阻应变片因此而发生电阻变化,破坏原先的惠斯顿电桥电路平衡,电桥输出与压力成正比的电压信号。

电容式压力传感器利用MEMS技术在硅片上制造出横隔栅状,上下二根横
隔栅成为一组电容式压力传感器,上横隔栅受压力作用向下位移,改变了上下二根横隔栅的间距,也就改变了板间电容量的大小,即△压力=△电容量。
