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3176B是一款低成本的IEPE加速度传感器/振动传感器,压电式应用原理,集成陶瓷应变片,频率响应低,低至0.3Hz。
The Dytran 3176B is a rugged, cost effective IEPE piezoelectric accelerometer with a sensitivity of 100 mV/g and excellent low frequency response of 0.3 Hz.
Design of the model 3176B incorporates a ceramic shear sensing element, packaged in a stainless steel housing with a 2-pin MIL-C-5015 axial connector and 10-32 stud mounting capabilities. Model 3176B is hermetically sealed for reliable operation in high humidity and dirty environments and internally case isolated to avoid EMI/ground loop interference.
