扩散硅压力传感器原理

扩散硅压力传感器原理
硅压力传感器是一种常用的压力测量装置,其原理基于硅晶圆的应变敏感性。
以下为扩散硅压力传感器的工作原理。
扩散硅压力传感器由一个圆形的硅晶圆组成,其表面镀有硅二氧化层以提高机械强度和保护内部电路。
在硅晶圆的一侧,有一块“绝缘底座”用于固定传感器。
压力传感器的另一边被称为“感应表面”,通过开孔与外界相通。
当外界施加压力时,感应表面上的硅会受到应变,导致其电阻发生变化。
这种应变敏感性是基于硅晶圆的压力敏感效应。
在传感器的内部,有一个电阻栅极用于测量感应表面上的电阻变化。
当施加压力时,感应表面上的硅发生应变,改变了电阻栅极的电阻。
这个变化的电阻值可以通过外部电路进行测量和转换,从而得到压力值的相关信号。
扩散硅压力传感器具有很高的精度和灵敏度。
它们可以广泛用于工业、医疗和汽车等领域,用于测量液体和气体的压力。

WPD-102 压力传感器说明手册说明书

WARNING Ensure that the maximum individual port pressure doesnot exceed the maximum pressure range of the unit. For example, the maximum individual port pressure on a WPD-102 is 100 PSI. Exceed-ing this may damage the sensors and WILL give erroneous readings.WARNING Do not use in an explosive or hazardous environment, with combustible or flammable gasses, as a safety or emergency stop device or in any other application where failure of the product could result in personal injury. Use electrostatic discharge precautions during installation and do not exceed the device ratings.MOUNTING The transmitter mounts on a vertical surface with the pressure ports and cable entrance on the bottom using the two screw holes on the base of the unit. Ensure there is enough space around the unit to make the pressure and electrical connections. Avoid locations with severe vibrations or excessive moisture. The enclosure has a standard ½” conduit opening and may be installed with either a conduit coupler or a cable gland type fitting. In this position the High port is on the left and the Low port is on the right as shown on the pcb.WIRING Use 22 awg shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply induc-tive loads such as motors. Disconnect the power supply before making any connections to prevent electrical shock or equipment damage. Make all connec-tions in accordance with national and local electrical codes.This device is a 3-wire sourcing type transmitter. Connect the positive dc voltage or the hot side of the ac voltage to the terminal marked PWR . The power supply common is connected to the terminal marked COM . The device is reverse voltage protected and will not operate if connected backwards. The analog output signal is available on the OUT terminal. This signal is jumper selectable for either voltage or 4-20 mA output. In voltage mode, either 0-5 or 0-10 Vdc can also be selected. These options are indicated on the circuit board.The remote zero feature may be used by wiring a dry-contact (relay only) digital output to the ZERO terminals. Do not apply voltage to the ZERO terminals.PLUMBING The two pressure ports are labeled High and Low . The out-put signal indicates a positive value when the pressure is higher on the High port than the Low port so ensure these ports are connected correctly. Use an appropriately rated pressure tubing and arrange it to minimize stress on the connections.Do not allow material to fall into the pressure ports as contamination could damage the sensors.CONFIGURATION As shown on the pcb drawing, push-on jumpers and switches are used to select the output signal type, the input pressure range and several features. The device is factory configured to operate in the 4-20 mA output mode but can be changed to voltage mode by moving the two jumpersfrom the positions marked Current to the positions marked Voltage . Always note the current jumper position first and then move them to the new position.If the jumpers are rotated 90 degrees and installed incorrectly the product will not work and damage may occur. In voltage mode the output scale may be changed to either 0-5 or 0-10 Vdc by moving the single jumper to the 5V or 10V position.The Range and Options switches can be changed while the unit is operating. However, the output jumpers can only be changed while the power is removed.The jumper marked Light is for the LCD back-light option. The back-light is enabled in the On position but can be set to Off to reduce power consumption. The input pressure range (as shown on the product label) is set by moving the 4-position slide switch marked RANGE .Bidirectional operation, port swap, slow damping and analog reverse functions are available by switching the appropriate DIP switch position to ON.BIDIRECTIONAL This switch changes the range from 0 to full scale differ-ential pressure to minus full scale to plus full scale differential pressure. The analog output will read ½ when the differential pressure is zero. The example below shows the results when a Model 2 (0 to 100 psi) is operated in bidirec-tional mode (-100 to 100 psi).PORT SWAP This switch reverses the polarity of the pressure ports. It makes the HIGH port “low” and the LOW port “high”. This is useful to correct plumbing errors.SLOW DAMPING This switch provides an 8-second averaging for surge dampening (normally it is 4-seconds).OUTPUT REVERSE This switch reverses the output signal polarity. In reverse mode the analog output is maximum when the pressure differential is zero and decreases as pressure increases.OPERATION For normal operation such as 0-100 PSI, the pressure applied to the High port must be higher than the pressure applied to the Low port. If the pressure connection is reversed then the transmitter will always output 4 mA or 0 V. If the Low port is left open to ambient pressure, then the High port is used to measure a positive pressure and 0 PSI = 4 mA and 100 PSI = 20 mA.Model 1 2 3 4 101 50 PSI 25 PSI 10 PSI 5 PSI 102 100 PSI 50 PSI 20 PSI 10 PSI 103 200 PSI 100 PSI 40 PSI 20 PSI 104 500 PSI 250 PSI 100 PSI 50 PSI 105 5.0 Bar 2.5 Bar 1.0 Bar 0.5 Bar 106 7.50 Bar 3.75 Bar 1.50 Bar 0.75 Bar 107 10 Bar 5 Bar 2 Bar 1 Bar 108 30 Bar 15 Bar 6 Bar 3 Bar 109 500 kPa 250 kPa 100 kPa 50 kPa 110 750 kPa 375 kPa 150 kPa 75 kPa 111 1000 kPa 500 kPa 200 kPa 100 kPa 1123000 kPa1500 kPa600 kPa300 kPaPressure Range Wet-WetDifferential Pressure TransducerInstallation InstructionsHIGH port LOW port LCD 4-20 mA 0-5 V 100 PSI 50 PSI 50 PSI 16 mA 3.75 V 50 PSI 100 PSI -50 PSI 8 mA 1.25 V 50 PSI 50 PSI 0 PSI 12 mA 2.5 V 100 PSI0 PSI100 PSI20 mA5 VFor bidirectional operation such as +/-100 PSI, the pressure applied to the High port should be higher than the pressure applied to the Low port for a positive output response. Negative pressure is indicated if the High pressure is less than the Low pressure. In this case –100 PSI = 4 mA and +100 PSI = 20 mA. Since the transmitter is linear 0 PSI = 12 mA.CALIBRATION With both ports open to the ambient pressure (or with both ports equalized at 0 pressure), press and hold the auto-zero button or provide contact closure on the ZERO terminals for at least 3 seconds. Release the button or terminals and the device will calculate and store the new zero point. To protect the unit from accidental zeroing this feature is enabled only when the detected pressure on both ports is less than 5% of the full range. It is not recommended that the span calibration be performed in the field unless a high quality calibrator is available.

扩散硅压力传感器工作原理

扩散硅压力传感器工作原理
硅压力传感器是一种基于硅材料的传感器,用于测量压力。
其工作原理基于压力对硅芯片的变形产生的电阻变化。
硅压力传感器的核心部件是一个薄膜型硅压阻元件,通常由硅晶圆加工而成。
该元件由两层硅薄膜组成,上层为引压膜,下层为探测膜。
当外界施加压力作用在传感器上时,引压膜和探测膜之间的硅材料会产生一定程度的变形。
这种变形会改变硅材料的电阻特性,从而使得传感器的输出信号发生变化。
硅压力传感器通常采用电桥测量电路将这个电阻变化转化为电压输出。
通过对电桥进行精确的电压测量,就可以实现对外界压力的准确测量。
硅压力传感器的灵敏度和稳定性主要取决于硅材料的特性以及传感器的制造工艺。
传感器内部通常还会加入温度补偿电路,以消除温度对测量结果的影响。
另外,传感器还需要进行标定和校准,以确保其测量结果的准确性和可靠性。
总结来说,硅压力传感器通过测量硅芯片在压力作用下的变形,利用电桥测量电路将其转化为电压输出,实现对压力的测量。
它具有高灵敏度、稳定性好等特点,广泛应用于工业控制、汽车、医疗设备等领域。
