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3202A是一款IEPE加速度傳感器/振動傳感器，內(nèi)建靜電屏蔽，防噪防靜電，自帶2針MIL-C5015接口和1/4-28的螺紋通孔。
The Dytran 3202A is a high sensitivity, ring style IEPE piezoelectric accelerometer with internal Faraday shield for electrostatic noise immunity, featuring a radial 2-pin MIL-C-5015 connector and 1/4-28 thru hole mount, allowing the sensor to be turned 360° prior to securing for greater ease of installation.
Available with a sensitivity of 100 mV/g, the model 3202A has a low end frequency response of 0.5 Hz and excellent low noise performance characteristics. Design of the model 3202A incorporates a ceramic shear sensing element, packaged in a highly rugged stainless steel housing. Units are hermetically sealed for reliable operation in high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
