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3055D1是一款IEPE加速度傳感器/振動傳感器，靈敏度10 mV/g，自帶電量放大器，通過10-32螺紋孔可安裝振動頭。
The Dytran model 3055D1 is a cost effective, single axis IEPE accelerometer offered with a sensitivity of 10 mV/g.
Design of the model 3055D1 features a ceramic shear sensing element packaged within a rugged titanium housing, and incorporates a 10-32 radial connector and 10-32 stud mounting capabilities. Model 3055D1 is base isolated to avoid EMI/ground loop interference and incorporates low noise JFET electronics. Units are also hermetically sealed for reliable performance in high humidity and dirty environments
