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(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3256A1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，性能可靠，即使在潮濕和多塵環(huán)境下。
The Dytran 3256A1 is a cost effective, single axis IEPE accelerometer. Available with a sensitivity of 10 mV/g, the model 3256A1 features wide bandwidth and incorporates a ceramic shear sensing element packaged in a durable titanium housing, with a 10-32 axial connector and 10-32 stud mounting capabilities. Units incorporate low noise JFET electronics and are hermetically sealed for reliable performance in high humidity and dirty environments.
