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3211M1是一款I(lǐng)EPE加速度傳感器/振動(dòng)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 3211M1 is a low profile IEPE accelerometer with a 10 mV/g sensitivity, weighing just 10 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 and integral low noise JFET electronics, encased within a rugged, lightweight titanium housing. The sensor is base isolated to avoid EMI/ground loop interference and mounts via #8 or M4 mounting screws.
Units are hermetically sealed for reliable operation in high humidity and dirty environments. A miniature thru hole design allows the sensor to be turned 360° prior to securing for ease of sensor installation.
