摘　　要：阐述一种基于科里奥利质量流量计幅值、频率可调的自动增益控制模拟驱动电路,在流量管没有外部输入信号时能够通过自激振荡输出一个激励流量管起振的正弦波信号,并在流量管信号发生幅值改变时能够自动稳定幅值在流量管的最佳振幅内。This paper describes an analog drive circuit of automatic gain control based on the adjustable amplitude and frequency of Coriolis mass flowmeter.When there is no external input signal of the flow tube,it can output a sine wave signal to stimulate the flow tube to vibrate through self-excited oscillation,and automatically stabilize the amplitude within the optimal amplitude of the flow tube when the amplitude of the flow tube signal changes.

关 键 词：质量流量计 模拟驱动 正弦波振荡电路 幅值控制
