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3214A1是一款I(lǐng)EPE加速度傳感器/振動傳感器，靈敏度10 mV/g，集成低噪低噪JFET電子元件，性能可靠，可在潮濕和多塵環(huán)境下正常工作。
The Dytran 3214A1 is a cost effective single axis IEPE accelerometer available with a sensitivity of 10 mV/g. Units feature a wide bandwidth, 10-32 radial connector and 10-32 stud mounting capabilities. The model 3214A1 incorporates low noise JFET electronics and is hermetically sealed for reliable performance in high humidity and dirty environments.
