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(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3217AA是一款I(lǐng)EPE加速度傳感器/振動傳感器，自帶10集成電纜線，可在水下175psi環(huán)境下正常工作。
The Dytran 3217A is a low profile IEPE accelerometer with a 100 mV/g sensitivity, weighing just 5 grams. The sensor features a factory molded urethane boot and a 10-foot integral urethane cable, for reliable operation in water depths to 175 psi.
Sensor design incorporates a ceramic shear sensing element for high natural frequency, along with low noise electronics, encased in a rugged lightweight titanium housing. The sensor is base isolated to avoid EMI/ground loop interference and is offered with adhesive mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
