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(jìn)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3128A是一款超高靈敏度的IEPE加速度傳感器/振動傳感器，靈敏度高達(dá)1000mV/g，專為井下鉆頭振動監(jiān)測和其他低開啟電壓應(yīng)用而設(shè)計。
The Dytran 3128A is an IEPE accelerometer with ultra high sensitivity of 1,000 mV/g and was designed for down-hole drill head vibration monitoring and other low turn-on voltage applications where supply power is limited.
Sensors developed for down-hole vibration monitoring must be able to deliver accurate and reliable data, while simultaneously tolerating harsh conditions. Critical characteristics of these sensors include a low-profile design, broad operating temperature, and the ability to operate at low power levels. The Dytran model 3128A is ideal for such applications, as it is packaged in a low profile stainless steel housing with a vertical height of just 1.16-inches (29.5-millimeters) and was specially designed to operate from +2.0 to +3.5 VDC bias voltage.
The Dytran model 3128A is designed with 10-32 mounting capabilities and 10-32 radial connector. Units are case isolated to avoid EMI/ground loop interference and are hermetically sealed for reliable operation in high humidity and dirty environments.
