| 摘 要： | 一切测量结果都不可避免地具有不确定度。根据CNAL/AC01∶2005《检测和校准实验室认可准则》的要求,校准实验室对所有校准项目的测量不确定度都应进行评定,必须给出每个测量结果的不确定度。文章以0.25级精密压力表和0.5级压力变送器为例,对其测量不确定度的评定进行阐述。

| Abstract: | Each measurement result has its uncertainty character.According to the requirements of CNAL/AC01:2005 Lab accredited guideline of measurement and calibration,calibration lab should assess measuring uncertainty for each measuring item,and should present uncertainty for each measuring result.The paper takes the 0.25precision pressure gauge and 0.5pressure transmitter as example,and makes a discussion about its measuring uncertainty. |

| Keywords: | precision pressure gauge pressure transmitter measuring uncertainty assessment |
