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3312A2T是一款IEPE加速度傳感器/振動傳感器，靈敏度10 mV/g，自帶10-32接口和10-32螺紋，適用于模態(tài)分析實驗。
The Dytran 3312A2T is a unique IEPE piezoelectric accelerometer utilizing an ultra low frequency response while simultaneously featuring a robust, low profile design.
Measuring just 0.73-inches (18.4-millimeters) tall, the Dytran model 3312A2T offers a frequency response of 0.1 to 4,000 Hz. Units incorporate a ceramic shear sensing element, packaged in a hermetically sealed titanium housing weighing 25 grams, and incorporate a 10-32 radial connector and 10-32 mounting hole. Offered with a 100 mV/g sensitivity, the Dytran model 3312A2T incorporates IEEE 1451.4 TEDS capabilities for use in larger channel count applications.
The Dytran model 3312A2T is ideal for use in modal analysis testing where the user needs to measure low-level vibrations but wants to use a piezoelectric accelerometer, as opposed to a DC sensor. Additionally, units are ideal for seismic monitoring where compact size is required.
