摘　　要：根据RTD峰值电压Vp与串联电阻RS、外加电阻Rex的关系,提出一种新的测量RTD串联电阻RS的方法.实验证明该方法具有准确、简便、快速等特点.文中给出Vp与RS,Rex关系的推导,RS测量原理、测量结果和与其他RS测量方法的比较.According to the relation among peak voltage Vp, series resistance Rs, and external resistance Rex, a novel method for measuring the series resistance R s of RTDs is proposed. The experimental result demonstrates that this method is accurate, simple, convenient, and quick. The derivation of the relation among Vp, R s, and R ex, the principle of R s measurement, the measured result of Rs ,and a comparison between this method and other measurement methods are illustrated in detail.
