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生的電量是很小的，因此傳感器產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3019A是一款小型IEPE加速度傳感器/振動傳感器，自帶1/4-28尺寸的通螺紋孔及2針MIL-C-5015接頭，上線頻率響應達8000Hz。
The Dytran 3059A is a low profile IEPE piezoelectric accelerometer featuring a thru hole 1/4-28 mount and radial 2-pin MIL-C-5015 connector. This unique configuration allows the sensor to be turned 360° prior to securing for ease of sensor installation.
Available with a sensitivity of 100 mV/g, design of the model 3059A incorporates a ceramic shear sensing element packaged in a highly rugged stainless steel housing. With a low-end frequency response of 0.5 Hz and excellent low noise performance, the model 3059A is ideal for vibration monitoring of slowly rotating machinery and other equipment. Units are hermetically sealed for reliable operation in high humidity and dirty environments, and are internally case isolated to avoid EMI/ground loop interference.
