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3056D8是一款IEPE加速度传感器/振动传感器，灵敏度5mV/g，集成陶瓷剪切感应元件，钛合金外壳，应对潮湿和多尘的恶劣工作环境。
The Dytran model 3056D8 is a cost effective, single axis IEPE accelerometer offered with a sensitivity of 5 mV/g.
Design of the Dytran 3056D8 features a ceramic shear sensing element packaged within a rugged titanium housing, and incorporates a 10-32 axial connector and 10-32 stud mounting capabilities. Model 3056D7 is base isolated to avoid EMI/ground loop interference and incorporates low noise JFET electronics. Units are also hermetically sealed for reliable performance in high humidity and dirty environments.
