摘要
激振电路是科里奥利质量流量计的重要组成部分。作者研制了激振电路 ,分析了它的特性和原理 ,并进行了 EDA仿真和实验。结果表明 ,该激振电路能够驱动测量管振动 ,并保持其振幅稳定 ,实现了振动频率随管子的固有振动频率而变化的目的 ,从而达到了设计要求。
The excitation circuit is one of the important parts of Coriolics mass flowmeters. In this paper,an excitation circuit is developed, and its characteristics and operating principle are analyzed. Simulations by EDA and the experiments are carried out. The results indicate that the excitation circuit makes the measuring tubes oscillate at the natural resonant frequency and maintains the oscillating magnitude stable, so that the design requirements are satisfied.
