IEPE是指一种自带电量放大器或电压放大器的加速度传感器。IEPE是压电集成电路的缩写。因为由加速度传感器产生的电量是很小的，因此传感器产生的电信号很容易受到噪声干扰，需要用灵敏的电子器件对其进行放大和信号调理。IEPE中集成了灵敏的电子器件使其尽量靠近传感器以保证更好的抗噪声性并更容易封装。
美国Dytran的3312A2T是一款IEPE加速度传感器/振动传感器，灵敏度10 mV/g，自带10-32接口和10-32螺纹，适用于模态分析实验。
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.
