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3306A1是一款IEPE加速度传感器/振动传感器，可在低至196摄氏度环境下连续正常工作，满足低温振动试验要求。
The Dytran 3306A1 is an IEPE accelerometer with continuous operation to -320°F (-196°C), expressly designed to support cryogenic vibration testing requirements.
Offered with a 5 mV/g sensitivity, the design of model 3306A1 incorporates a two-pole low pass filter, which aids in eliminating spurious high frequency data, and a rugged stainless steel construction, along with a 1/4-28 integral mounting stud and an axial mounted, military style 3-pin Bayonet connector. Even at extreme temperatures, the model 3306A1 displays an extremely stable and continuous signal output. Units are hermetically sealed for reliable operation in high humidity and dirty environments. The accelerometer is also electrically isolated via use of an internal Faraday shield for noise immunity.
