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3030B4是一款微型IEPE加速度傳感器/振動傳感器，自帶電量放大功能，重量僅6.8g。
The Dytran 3030B4 is a miniature IEPE piezoelectric accelerometer, weighing just 6.8 grams.
Available with a 10 mV/g sensitivity and 500g shock limit, the model 3030B4 features a rugged stainless steel construction and an abbreviated low-end frequency response of 2 Hz, ensuring sensitivity stability during rapid thermal transient conditions. Units are hermetically sealed for reliable operation in high humidity and dirty environments and incorporate a 10-32 mounting stud and 10-32 axial connector.
