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3185D是一款I(lǐng)EPE加速度傳感器/振動傳感器，內(nèi)建靜電屏蔽，防噪防靜電，低頻響，靈敏度100mV/g。
The Dytran 3185D is a highly rugged IEPE accelerometer with a built-in Faraday shield for electrostatic noise immunity, a sensitivity of 100 mV/g and excellent low frequency response.
Design of the model 3185D incorporates a ceramic shear sensing element, packaged in a stainless steel housing with a TNC axial connector and 1/4-28 stud mounting capabilities. The model 3185D is designed to be directly compatible with the Dytran model 6185 Immersion Proof boot. When used together, the sensor remains fully functional in an IP65 environment. The model 3185D is hermetically sealed for reliable operation in high humidity and dirty environments and base isolated to avoid EMI/ground loop interference.
