產品簡介

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

詳細介紹

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生的電量是很小的，因此傳感器產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3192A是一款IEPE加速度傳感器/振動傳感器，靈敏度1V/g，頻響低至0.5Hz。

The Dytran 3192A is a rugged IEPE piezoelectric accelerometer with a sensitivity of 1 V/g, a built-in Faraday shield for electrostatic noise immunity, excellent low frequency response of 0.5 Hz and the capability to resolve vibrations as low as 0.00007 g's RMS.

Design of the model 3192A incorporates an annular shear ceramic sensing element, packaged in a stainless steel housing with a 2-pin MIL-C-5015 axial connector and 1/4-28 mounting hole. The sensor is hermetically sealed for reliable operation in high humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
