產(chǎn)品簡(jiǎn)介
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(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3191A是一款I(lǐng)EPE加速度傳感器/振動(dòng)傳感器，內(nèi)建靜電屏蔽，防噪防靜電，頻響低至0.08Hz，自帶電量放大器。
The Dytran 3191A is an IEPE piezoelectric accelerometer with built-in Faraday shield for electrostatic noise immunity, excellent low frequency response of 0.08 Hz and the capability to resolve vibrations as low as 0.000001 g's RMS.
Available with a sensitivity of 5 V/g, design of the model 3191A incorporates an annular shear ceramic sensing element, packaged in a highly rugged stainless steel housing with a 2-pin MIL-C-5015 axial connector and 1/4-28 mounting hole. The model 3191A was designed to be directly compatible with the Dytran model 6194 Immersion Proof sealing boot (sold separately). When used together, the sensor remains fully functional in an IP65 environment. The sensors are hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
