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3030B4是一款微型IEPE加速度传感器/振动传感器，自带电量放大功能，重量仅6.8g。
The Dytran 3030B4 is a miniature IEPE piezoelectric accelerometer, weighing just 6.8 grams.
Available with a 10 mV/g sensitivity and 500g shock limit, the model 3030B4 features a rugged stainless steel construction and an abbreviated low-end frequency response of 2 Hz, ensuring sensitivity stability during rapid thermal transient conditions. Units are hermetically sealed for reliable operation in high humidity and dirty environments and incorporate a 10-32 mounting stud and 10-32 axial connector.
