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3205B是一款高性能IEPE加速度传感器/振动传感器，可在高达175摄氏度工作环境下运行，专为井下钻头振动监测和其他低开启电压应用而设计。
The Dytran 3205B is a high performance IEPE accelerometer capable of operating at temperatures up to +347°F (+175°C) and was designed for down-hole drill head vibration monitoring and other low turn-on voltage applications where supply power is limited.
Sensors developed for down-hole vibration monitoring must be able to deliver accurate and reliable data, while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a miniature design, high temperature operation, and the ability to operate at low power levels. The Dytran model 3205B is ideal for such applications, as it is packaged in a miniature titanium housing with a vertical height of just 0.28-inches (7.1-millimeters) and was specially designed to operate from +4.0 to +4.5 VDC compliance voltage.
The Dytran model 3205B is offered with a 2 mV/g sensitivity and is designed with adhesive mounting capabilities. Weighing just 2 grams, units incorporate a 35-inch integral cable assembly terminating to flying leads.
