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?yàn)橛杉铀俣葌鞲衅鳟a(chǎn)生的電量是很小的，因此傳感器產(chǎn)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(jìn)行放大和信號調(diào)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3027B是一款I(lǐng)EPE加速度傳感器/振動傳感器，靈敏度>10 mV/g，自帶電量放大器，通過10-32螺紋孔可安裝振動頭。

The Dytran 3027B is a double ended IEPE reference (comparison) accelerometer, offering a convenient means of determining the sensitivity and frequency response characteristics of unknown acceleration, velocity and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the model 3027B to accomplish in-house NIST traceable calibrations. Model 3027B offers a >10 mV/g sensitivity, and mounts to a shaker head via a 10-32 tapped hole.

Back-to-back comparisons with a double ended calibration standard accelerometer, such as the Dytran model 3027B, entails mounting the test accelerometer directly to the top mounting surface of the calibration standard (model 3027B) and driving the coupled pair with an electrodynamic shaker system at various frequencies and amplitudes. At each test frequency, the amplitude is set and the corresponding output read from the test accelerometer. To form a complete measurement system, the user will need to supply the cables, power supply unit and electrodynamic shaker system. The model 3027B should be used for low frequency, low g level measurements.
