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3148E是一款防潮型加速度传感器/振动传感器,灵敏度100mV/g,低频,低至0.5Hz。
The Dytran 3148E is a highly rugged IEPE accelerometer with a 100 mV/g sensitivity and low frequency vibration measurement capabilities down to 0.5 Hz.
Design of the model 3148E incorporates a ceramic shear sensing element packaged in a stainless steel housing, incorporating a radial BNC connector and 10-32 mounting hole. The model 3148E is also hermetically sealed for reliable operation in high humidity and dirty environments and base isolated to avoid EMI/ground loop interference.
