IEPE是指一種自帶電量放大器或電壓放大器的加速度傳感器。IEPE是壓電集成電路的縮寫。因為由加速度傳感器產(chǎn)生的電量是很小的，因此傳感器產(chǎn)生的電信號很容易受到噪聲干擾，需要用靈敏的電子器件對其進行放大和信號調(diào)理。IEPE中集成了靈敏的電子器件使其盡量靠近傳感器以保證更好的抗噪聲性并更容易封裝。
美國Dytran的3176B是一款低成本的IEPE加速度傳感器/振動傳感器，壓電式應用原理，集成陶瓷應變片，頻率響應低，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.
