产品简介
IEPE是指一种自带电量放大器或电压放大器的加速度传感器。IEPE是压电集成电路的缩写。因为由加速度传感器产生的电量是很小的，因此传感器产生的电信号很容易受到噪声干扰，需要用灵敏的电子器件对其进行放大和信号调理。IEPE中集成了灵敏的电子器件使其尽量靠近传感器以保证更好的抗噪声性并更容易封装。
美国Dytran的3077A是一款IEPE加速度传感器/振动传感器，适用于高频振动监测，灵敏度10mV/g，频率响应1.1-5000Hz。
The Dytran 3077A is an IEPE piezoelectric accelerometer, designed expressly for Rotor, Track and Balance (RTB) and other high frequency aircraft vibration monitoring applications.
Offered with a sensitivity of 10 mV/g, frequency response of 1.1 to 5,000 Hz, and a 3-foot integral cable, the distinguishing feature of model 3077A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined. This unique design also offers reduced mass, as compared to conventional sensors and mounting brackets. Dytran's model 3077A is hermetically sealed for reliable operation within high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference.
