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3232A1一款两轴IEPE加速度传感器/振动传感器,专门为状态与使用监控系统而设计,10 mV/gd的灵敏度,自带3针接口与5/16-28螺纹孔设计。

The Dytran 3232A1 is a biaxial IEPE piezoelectric accelerometer, designed for use in Health and Usage Monitoring Systems (HUMS) as well as Active Vibration Control (AVC) applications typically found on commercial and military aircraft. Units are offered with a sensitivity of 10 mV/g and incorporate a radial 3-pin "Mighty Mouse™" connector with 5/16-28 thread.

The distinguishing feature of model 3232A1 is its Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs typically associated with separate mounting brackets. Units also offer reduced mass, as compared to conventional sensors and mounting brackets. The Dytran model 3232A1 is hermetically sealed for reliable operation within high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
