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3217AA是一款IEPE加速度传感器/振动传感器,自带10集成电缆线,可在水下175psi环境下正常工作。

The Dytran 3217A is a low profile IEPE accelerometer with a 100 mV/g sensitivity, weighing just 5 grams. The sensor features a factory molded urethane boot and a 10-foot integral urethane cable, for reliable operation in water depths to 175 psi.

 

Sensor design incorporates a ceramic shear sensing element for high natural frequency, along with low noise electronics, encased in a rugged lightweight titanium housing. The sensor is base isolated to avoid EMI/ground loop interference and is offered with adhesive mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
