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3062A是一款IEPE加速度传感器/振动传感器,专门为商用飞机振动监测和军事制造,集成一体的高耐久性石英剪切技术。10 mV/gd的灵敏度,同时具有微型通孔的设计

Expressly designed for commercial and military aircraft vibration monitoring, the Dytran 3168F is a ring style IEPE piezoelectric accelerometer incorporating the use of high stability quartz shear technology.

The model 3168F is offered with a 10 mV/g sensitivity and features a miniature thru hole design, allowing the sensor to be turned 360° prior to securing for ease of sensor installation. Units are hermetically sealed for reliable operation in high humidity and dirty environments, as well as case isolated to avoid EMI/ground loop interference. Case ground isolation is achieved by internally isolating the accelerometer element, complete with Faraday shield, from the outer housing.

The Dytran model 3168F features an integral 4-foot molded Viton™ cable, terminating in twisted shielded pair flying leads. Custom lengths and connectors are also available; consult the factory for details.
