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3234A1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10-32接口和10-32螺紋，集成陶瓷剪切感應(yīng)元件。
The Dytran 3234A1 is a single axis IEPE accelerometer, with a unique cubic design and is available with a 10 mV/g sensitivity. Model 3234A1 incorporates a ceramic shear sensing element, packaged in a rugged titanium housing weighing 12 grams. Units are base isolated to avoid EMI/ground loop interference.
Featuring a 10-32 radial 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
