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3148E是一款防潮型加速度傳感器/振動傳感器，靈敏度100mV/g，低頻，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.
