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3192A是一款IEPE加速度传感器/振动传感器，灵敏度1V/g，频响低至0.5Hz。

The Dytran 3192A is a rugged IEPE piezoelectric accelerometer with a sensitivity of 1 V/g, a built-in Faraday shield for electrostatic noise immunity, excellent low frequency response of 0.5 Hz and the capability to resolve vibrations as low as 0.00007 g's RMS.

Design of the model 3192A incorporates an annular shear ceramic sensing element, packaged in a stainless steel housing with a 2-pin MIL-C-5015 axial connector and 1/4-28 mounting hole. The sensor is hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
