本文主要阐述了实验室在参加CNAS M0071压力变送器校准能力验证计划后,参考在测量结果不确定度评定中出现的问题,提出使用数字压力计作为计量标准装置的情况下,对压力变送器校准结果的不确定度进行评定。
This article mainly elaborates the laboratory to participate in CNAS M0071 pressure transmitter calibration capability verification plan, the reference to the measurement uncertainty in the assessment of the problems that the use of digital pressure gauge as a measurement standard device, the pressure transmitter Uncertainty of the calibration result of the instrument is evaluated.
