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3097A1是一款微型IEPE加速度傳感器/振動(dòng)傳感器,靈敏度10mV/g,自帶電量放大功能。
The Dytran 3097A1 is a lightweight miniature IEPE accelerometer, offered with a sensitivity of 10 mV/g.
The accelerometer incorporates a ceramic shear sensing element and ultra low noise JFET electronics, with materials housed in a highly durable 0.4-inch (10.2 millimeter) laser welded titanium cube weighing just 4.3 grams. The model 3097A1 features a 5-40 tapped hole and industry standard 10-32 radial connector.
