锁相环路在流量变送器中的应用

Application of the phase locked loops in the flow transducer

变送器的功能是将各种工艺参数变换成相应的统一标准信号.本文介绍利用锁相环路实现流量变送器的设计方法,并介绍变换电路,给出了电路的参数.

Function of the transducer transfer Unitarian standard signal from all kinds of craft parameter.The design mode of the phase locked loops circuit for flow transducer is introduced in this article.The circuit parameter is discussed specially in this paper.
