IEPE是指一种自带电量放大器或电压放大器的加速度传感器。IEPE是压电集成电路的缩写。因为由加速度传感器产生的电量是很小的,因此传感器产生的电信号很容易受到噪声干扰,需要用灵敏的电子器件对其进行放大和信号调理。IEPE中集成了灵敏的电子器件使其尽量靠近传感器以保证更好的抗噪声性并更容易封装。
美国Dytran的3027B是一款IEPE加速度传感器/振动传感器,灵敏度>10 mV/g,自带电量放大器,通过10-32螺纹孔可安装振动头。
The Dytran 3027B is a double ended IEPE reference (comparison) accelerometer, offering a convenient means of determining the sensitivity and frequency response characteristics of unknown acceleration, velocity and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the model 3027B to accomplish in-house NIST traceable calibrations. Model 3027B offers a >10 mV/g sensitivity, and mounts to a shaker head via a 10-32 tapped hole.
Back-to-back comparisons with a double ended calibration standard accelerometer, such as the Dytran model 3027B, entails mounting the test accelerometer directly to the top mounting surface of the calibration standard (model 3027B) and driving the coupled pair with an electrodynamic shaker system at various frequencies and amplitudes. At each test frequency, the amplitude is set and the corresponding output read from the test accelerometer. To form a complete measurement system, the user will need to supply the cables, power supply unit and electrodynamic shaker system. The model 3027B should be used for low frequency, low g level measurements.
