温湿度变送器温度测量误差的不确定度评定

Evaluation of Uncertainty for Temperature Measurement Error of Temperature and Humidity Transmitter

近年来,温湿度变送器的送检量逐渐增大,为保证其量值的准确可靠,2021年12月22日,广西相关部门发布了JJF(桂) 106-2021《温湿度变送器校准规范》。本文依据该校准规范,对内(外)置温度传感器的温湿度变送器的温度测量误差进行不确定度分析与评定。

In recent years,the quantity of temperature and humidity transmitters has gradually increased,in order to ensure the accuracy and reliability of its quantity value,on December 22,2021,the relevant departments of GUANGXI issued JJF(GUI)106-2021"Temperature and Humidity Transmitters Calibration Specifications".According to this standard,the uncertainty analysis and evaluation of temperature measurement error of temperature and humidity transmitter with internal(external)temperature sensor are carried out in this paper.
