在线温度测量系统温度示值误差的不确定度评定

Uncertainty Evaluation of Temperature Indication Error in On-line Temperature Measurement System

在线温度测量系统广泛用于各类工业生产过程中对温度参数的实时测量和监控,是一种非常直观、操控方便的系统。但其结构复杂、牵涉广泛,一般不可拆卸送检。本文分析了现场检测时温度测量示值误差的不确定度来源,并对其测得值的不确定度进行评定。

On-line temperature measurement system is widely used in various industrial processes of real-time temperature parameters measuring and monitoring,and is very intuitive and easy to operate.But the measurement system structure is complex and widely involved,and generally can not be disassembled for inspection.In this pa-per,the sources of the temperature measuring uncertainty of indication error are analyzed,and the uncertainty of the measured value is evaluated.
