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3006A是一款防潮型加速度传感器/振动传感器,灵敏度高,自带电量放大器。
The Dytran 3006A is a moisture resistant, high sensitivity single axis IEPE accelerometer with an overall weight of 12 grams.
Featuring a stainless steel construction, 100 mV/g sensitivity, 10-32 mounting hole and low noise JFET electronics, the Dytran model 3006A incorporates a 10-foot integral cable with a splash-proof boot at the point of sensor and cable connection. The cable-to-accelerometer boot seal makes it possible for the sensor to be temporarily submerged during testing. Units are hermetically sealed for reliable operation in high humidity and dirty environments, and case isolated to avoid EMI/ground loop interference.
