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3089A是一款微型IEPE加速度傳感器/振動傳感器，靈敏度100mV/g，自帶電量放大功能。
The Dytran 3089A is a cost effective lightweight IEPE accelerometer, with an overall height of just 0.25 inches (6.5 millimeters) and a weight of 0.6 grams. Offered with a 10 mV/g sensitivity and 500g shock limit, the model 3089A incorporates a quartz crystal sensing element, operating in shear mode.
Model 3089A features a rugged stainless steel construction, integral wires and adhesive mounting. Units hermetically sealed for reliable operation in high humidity and dirty environments.
