压力变送器检定装置计量比对

Metrological Comparison of Pressure Transmitter Verification Device

中国铁路济南局集团有限公司计量所作为参比实验室参加了由山东省市场监督管理局组织的0.5级压力变送器项目量值比对,根据山东省计量科学研究院下发的“0.5级压力变送器比对实施方案”,比对结果通过传递标准在各压力下的示值及其扩展不确定度U(k=2)体现。参比实验室的测量结果与参考值之差在合理的预期之内,比对结果为满意。

China Railway Jinan Bureau Group Co.,Ltd.Metrology Institute as a reference laboratory participated in the 0.5 level pressure transmitter project value comparison organized by Shandong Market Supervision Administra⁃tion.According to the"0.5 level pressure transmitter comparison implementation plan"issued by Shandong Institute of Metrology Science,the comparison results are required to be the indicated values of the transfer criteria under vari⁃ous pressures and their extended uncertainty U(k=2).The difference between the measurement results of the partici⁃parting laboratory and the reference value is within reasonable expectation,and the comparison results are satisfactory.
