摘要
阐述了手持式内置微型差动式电荷放大器和频率补偿电路一体化的发动机振动传感器。使用ispPAC可编程器件制作自适应频率补偿电路,展宽了频带,拓宽了手持式传感器的应用范围。实验表明:该传感器具有灵敏度高、测量范围宽、温度误差小等特点,该传感器已投入现场应用,使用效果良好。
A composite motor vibration transducer with differential charge amplifier and adaptive frequency compensating circuit is introduced.An adapted frequency compensating circuit using a programmable unit of insPAC is adopted so that the frequency range is extended and the application of the manual transducer is enlarged.Performance test shows that the transducer has the characteristic of high sensitivity,wide measuring range and low temperature error.The transducer has been put into practice successfully.
