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(xiě)。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(hào)很容易受到噪聲干擾，需要用靈敏的電子器件對(duì)其進(jìn)行放大和信號(hào)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(guó)Dytran的3035B是一款微型IEPE加速度傳感器/振動(dòng)傳感器，靈敏度100mV/g，自帶電量放大功能。
The Dytran 3035B is a miniature IEPE accelerometer, available with a 100 mV/g sensitivity, an overall height of just 0.33 inches (8.3 millimeters) and a total weight of 2.5 grams.
Sensors feature a rugged stainless steel construction, 5-40 stud mount and 5-44 radial connector. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
