摘要
根据《JJF1059.1-2012测量不确定评定与表示》的通用方法及JJG882-2019《压力变送器检定规程》,对压力变送器的测量不确定度进行了详细的分析和评定,验证了用准确度等级为0.02级的数字压力计检定准确度等级为0.2级的压力变送器的可行性,为压力变送器的检定提供了可靠的保证。
The measurement uncertainty of indication error of the pressure transmitter is analyzed and evaluated in detail based on JJF1059.1-2012 general method for measurement uncertainty assessment and representation and JJG882-2019 pressure transmitter verification regulation,and the feasibility of using the digital pressure gauge with accuracy level of 0.02 has been verified,which provides reliable guarantee for the verification of pressure transmitter.
