This paper mainly introduces the calibration method of piezoelectricity pressure sensors in the pressure field testing.
介绍压力场测试中所采用的压电压力传感器的标定方法。
The touch mode capacitive pressure sensor not only has high sensitivity and many merits that other forms of capacitive pressure sensors have, but also has good segment linearity between the load pressure and the output capacitor within the range of operation.
接触式电容压力传感器不仅具有一般电容式传感器灵敏度高等优点，而且在其测量的压力范围内，传感器的输出电容与载荷呈分段线性关系，因此与其它需要改进电极结构和测量电路进行非线性补偿的电容式压力传感器来讲，具有结构简单、性能优越、抗过载能力和抗干扰能力强等优点。
