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3234A1是一款IEPE加速度传感器/振动传感器，灵敏度10 mV/g，自带10-32接口和10-32螺纹，集成陶瓷剪切感应元件。
The Dytran 3234A1 is a single axis IEPE accelerometer, with a unique cubic design and is available with a 10 mV/g sensitivity. Model 3234A1 incorporates a ceramic shear sensing element, packaged in a rugged titanium housing weighing 12 grams. Units are base isolated to avoid EMI/ground loop interference.
Featuring a 10-32 radial connector and 10-32 stud mounting capabilities, units incorporate low noise JFET electronics and are hermetically sealed for reliable performance in high humidity and dirty environments
