摘要
通过对涡街信号频谱的分析 ,发现涡街传感器主要干扰源为固有振荡频率 ,并设计了解决此种干扰的传感器放大电路。
Through analyzing the spectrum of the signals of vortex flow transducer,the author found that the vortex flowmeter is mainly disturbed by the frequency of natural oscillation,and designs the amplifying circuit of the transducer to solve this problem of disturbance.
