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3311A是一款高频IEPE加速度传感器/振动传感器，灵敏度50mV/g，重量3.3g。
The Dytran 3311A is a low profile, high frequency ring shaped IEPE accelerometer with a 50 mV/g sensitivity and an overall weight of just 3.3 grams.
The accelerometer was designed to reliably operate in temperatures up to +320°F (+160°C) and feature a unique sensing element to ensure greater stability over a wider temperature range. Designed in a lightweight laser welded titanium housing, electrical connection for the Dytran model 3311A is achieved via a specially designed coaxial glass-to-metal sealed 5-44 radial connector. The model 3311A also features a thru hole mounting configuration, 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 base isolated, to avoid EMI/ground loop interference.
