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3237A2是一款IEPE加速度传感器/振动传感器,频带宽,25 mV/gd的灵敏度,不锈钢架构,应对高度超市和多尘工作环境。

The Dytran 3237A2 is an IEPE piezoelectric accelerometer expressly designed to cover most wide-band frequency points of Rotor, Track and Balance (RTB); airframe; helicopter; and fixed wing aircraft. The industry has commonly referred to these sensors as “spark plug type", due to their similar appearance.

 

Available with a sensitivity of 25 mV/g, the Dytran model 3237A2 features a hermetically sealed stainless steel construction for use in high humidity and dirty environments, as well as case isolation to avoid EMI/ground loop interference. Units feature an axial mounted military-style 3-pin D38999 connector, 1/4-28 mounting thread and lockwire holes.
