在振动试验设备中,广泛地采用压电晶体传感器(加速度计),作为测量机械振动参数(加速度、速度位移)的换能元件。由压电传感器将被测振动参数值的变化转换成电讯号的变化,然后再加以量测。这种转换原理是基于传感器中压电晶体片受力后产生 In vibration test equipment, piezoelectric crystal sensors (accelerometers) are widely used as transducing elements for measuring mechanical vibration parameters (acceleration, velocity displacement). Piezoelectric sensors will change the value of the measured vibration parameters into changes in electrical signals, and then to be measured. This conversion principle is based on the sensor piezoelectric crystal produced by force
