| 摘 要： | 差阻式传感器诞生已80 a,5芯测量是一大技术进步。从4芯测量技术到5芯测量技术,有关文献资料未能同步更新,存在混淆现象。五芯差阻式传感器对电缆的绝缘要求较低;提高差阻式读数仪的测量准确度既必要且可能;用正反测电阻比可定量分析差阻式传感器电阻比测值误差;无量纲的电阻比,符合现行标准的表示法是以10-4为计数单位。

| Abstract: | The Carlson transducer has been 80 years,the five-core measurement is a major technological advancement.From four-core to five-core measurement techniques,the literature failed to update simultaneously,there is aliasing.The connecting cable insulation requirement of five-core Carlson transducer is lower.To improve the Carlson readout accuracy is both necessary and possible.For Carlson transducer,quantitative analysis of the resistance ratio error can be carried out by the pro and con resistance ratio.The ex... |
