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3302A是一款兩軸IEPE加速度傳感器/振動傳感器,專門狀態與使用監控系統和主動振動控制而設計,, 10 mV/gd的靈敏度,同時具有微型通孔設計

The Dytran 3302A is a biaxial IEPE piezoelectric accelerometer designed for use in Health and Usage Monitoring Systems (HUMS) as well as Active Vibration Control (AVC) applications typically found on commercial and military aircraft. Offered with a sensitivity of 10 mV/g, units incorporate a radial 3-pin "Mighty Mouse™" connector with a 5/16-28 thread.

Design of the Dytran model 3302A features quartz sensing elements, operating in shear mode and packaged in a compact stainless steel housing. The distinguishing feature of these accelerometers is their Dytran developed integral mounting bracket design, which facilitates improved sensor performance while eliminating costs associated with separate mounting brackets. They also offer a reduced mass, as compared to conventional sensors and mounting brackets. The Dytran model 3302A is hermetically sealed for reliable operation within high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
