电流变送器校准和测量能力(CMC)评定

Calibration and Measurement Capability Evaluation(CMC) of Current Transmitter

本文依据GUM法进行测量不确定度评定,介绍了用PTC-8300H交流采样及变送器校验装置测量涵普FPA型直流电流变送器的校准和测量能力(CMC)评定的过程及表示方法。为检定和校准实验室人员在类似CMC评定提供相应的借鉴。

In this paper,the uncertainty of measurement is evaluated according to GUM method.This paper introduces the process and expression method of DC current transmitter calibration and measurement capability evaluation with PTC-8300H AC sampling and transmitter calibration device.It can be used for verification and calibrarion laboratory personnel in similar CMC evaluation.
