压电压力传感器

基于压电效应（Piezoelectric effect），利用电气元件和其他机械把待测的压力转换成为电量，再进行相关测量工作的测量准确仪器。压电传感器只可以应用在动态测量当中。主要的压电材料是：磷酸二氢胺、酒石酸钾钠和石英。随着技术的发展，压电效应也已经在多晶体上得到应用了。例如：压电陶瓷，铌镁酸压电陶瓷、铌酸盐系压电陶瓷和钛酸钡压电陶瓷等等都包括在内。

以压电效应为工作原理的传感器是机电转换式和自发电式传感器。它的敏感元件是用压电材料制作而成的。当压电材料受到外力作用时表面会形成电荷，电荷通过电荷放大器、测量电路的放大以及变换阻抗以后，就会被转换成为与所受外力成正比关系的电量输出。它用来测量力以及可以转换成为力的非电物理量，例如：加速度和压力。

优点是：重量较轻、工作可靠、结构简单、信噪比高、灵敏度高以及信频宽等。

缺点是：有部分电压材料忌潮湿，因此需要采取一系列的防潮措施；

压阻压力传感器一般通过引线接入惠斯登电桥中。平时敏感芯体没有外加压力作用，电桥处于平衡状态（称为零位），当传感器受压后芯片电阻发生变化，电桥将失去平衡。若给电桥加一个恒定电流或电压电源，电桥将输出与压力对应的电压信号，这样传感器的电阻变化通过电桥转换成压力信号输出。电桥检测出电阻值的变化，经过放大后，再经过电压电流的转换，变换成相应的电流信号，该电流信号通过非线性校正环路的补偿，即产生了与输入电压成线性对应关系的4～20mA标准输出信号。
