摘要
研究了同轴线相位法含水率计的测量原理,设计了含水率计测量电路的总体方案;分析了该仪器的混频器、鉴相器、压频转换器及分时传输控制电路,并对电路进行了优化设计,进而提高了电路的抗干扰能力和测井电缆信道资源的利用效率.
Measurement theory of coaxial line phase water cut meter is discussed and total design scheme of its circuits is ascertained in this paper. The circuits of mixer, phase discriminator, voltage-to-frequency converter and time-sharing transmission control are analyzed. Further more, optimized design of the circuits is brought into effect so as to improve the ability of anti-jamming of the circuits and the utility efficiency of the channel source of wire.
