工业生产中压力测量系统测量结果不确定度研究

Study on Uncertainty of Measurement Results of Pressure Measuring System in Industrial Production

压力参数是工业生产中的一个重要过程参数,其测量结果准确与否关系工业生产水平一个重要标志。传统计量主要关注计量器具合格与否,未直接关注最终输出结果是否准确。保证最终输出结果的准确是产业发展的要求,也是传统计量向产业计量转型的要求。针对压力测量系统输出准确的问题进行研究,以JJF(陕)025-2020《配气台压力测量系统校准规范》为基础,结合压力测量系统在工业生产中最终输出的影响因素进行不确定度研究,是保证工业生产中最终输出结果准确的关键。

Pressure parameter is an important process parameter in industrial production.Whether its measurement result is accurate or not is an important symbol of industrial production level.Traditional measurement mainly focuses on the qualification of measuring instruments rather than the accuracy of final output results.Ensuring the accuracy of final output is the requirement of industrial development and the transformation from traditional measurement to industrial measurement.The research on the accuracy of the output of the pressure measurement system is based on JJF(Shaanxi)025-2020 calibration specification for the pressure measurement system of the gas distribution station,and combined with the influencing factors of the final output of the pressure measurement system in industrial production,which is the key to ensure the accuracy of the final output result in industrial production.
