一般压力表示值误差测量不确定度评定

Evaluation of Measurement Uncertainty for General Pressure Gauges Indication Error

本文根据JJG 52—2013《弹性元件式一般压力表、压力真空表和真空表》和JJF 1059.1—2012《测量不确定度评定与表示》,对一个1.6级压力表进行测量,详细分析了其示值误差测量结果不确定度评定过程。文中所述的评定方法对开展一般压力表建标、校准专业的技术人员在进行相关不确定度评定时起到一定的指导作用。

This article measures a 1.6 level pressure gauge based on JJG 52—2013 Elastic Element Pressure Gauges,Pressure-Vacuum Gauges and Vacuum Gauges for General Use and JJF 1059.1—2012 Evaluationand Expression of Uncertainty in Measurement,and analyzes in detail the uncertainty evaluation process of its indication error measurement results.The evaluation method described in the article plays a certain guiding role for technical personnel engaged in the establishment and calibration of general pressure gauges when conducting uncertainty assessments.
