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3311A是一款高頻IEPE加速度傳感器/振動傳感器，靈敏度50mV/g，重量3.3g。
The Dytran 3311A is a low profile, high frequency ring shaped IEPE accelerometer with a 50 mV/g sensitivity and an overall weight of just 3.3 grams.
The accelerometer was designed to reliably operate in temperatures up to +320°F (+160°C) and feature a unique sensing element to ensure greater stability over a wider temperature range. Designed in a lightweight laser welded titanium housing, electrical connection for the Dytran model 3311A is achieved via a specially designed coaxial glass-to-metal sealed 5-44 radial connector. The model 3311A also features a thru hole mounting configuration, allowing the sensor to be turned 360° prior to securing for ease of sensor installation. Units are hermetically sealed for reliable operation in high humidity and dirty environments as well as base isolated, to avoid EMI/ground loop interference.
