摘要
通过分析压力变送器的数学模型,依据JJF1059—1999《测量不确定度评定与表示》,阐述了数字压力计检定压力变送器的过程,以及示值误差测量不确定度的评定步骤,着重分析了不确定度的来源与评定方法,最终给出了测量结果的不确定度报告。
The mathematics model used in pressure transmitter are analyzed, the verification course of the digital pressure gauge and the evaluation process in measurement uncertainty of indication errors are expatiated, which based on the technical specifica- tion JJF 1059--1999《Evaluation and Expression of Uncertainty in Measurement》,the uncertainty source and evaluation method are analyzed especially, the measurement uncertainty report of measurement result are presented finally.
