Abstract: This article first introduces the structure of the pressure gauge instrument, analyzes the steps required for calibration in the calibration regulations, and then provides solutions to the problems that arise in daily work, so as to comprehensively introduce the technical issues in the entire calibration process of the pressure gauge. Strictly based on theory and starting from practical work, share solutions to problems in pressure gauge calibration work.
Key words: pressure gauge; metrological verification; safety protection
1压力表具体计量检定内容
1.1压力表外观及内部构造检查
在对压力表进行相关检定之前,检定人员首先要仔细检查压力表的外观,重点观察其外形有无变化、外观有无破损痕迹、玻璃表面有无破裂裂纹、压力表指针有无松动、外观漆面有无光滑度等。(剩余4305字)
