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3236A是一款IEPE加速度传感器/振动传感器，集成一体的高耐久性石英剪切技术。10 mV/gd的灵敏度，频响高达10000Hz。
The Dytran 3236A is a ring style piezoelectric IEPE accelerometer, designed to offer reliable performance in temperatures up to +300°F (+149°C).
Incorporating a quartz crystal operating in shear mode, the Dytran model 3236A is offered with a sensitivity of 10 mV/g and an upper frequency response of 10,000 Hz. Elements are housed in a stainless steel package weighing 28.1 grams and feature a radial 3-pin "Mighty Mouse™" connector, and a miniature thru hole design, allowing the sensor to be turned 360° prior to securing for ease of sensor installation. Units are hermetically sealed for reliable operation in high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
