摘要
根据JJG(铁道) 193—2017《机车车辆专用压力表》计量检定规程,阐述机车车辆专用压力表示值误差的测量方法和数学模型,分别评定使用数字压力计和活塞式压力计2种不同类型计量标准器开展检定时测量结果的不确定度,从而验证测量的可靠性。
According to metrological verification regulations stipulated in JJG(Railway) 193-2017 Bourdon Pressure Gauge for Railway Locomotives and Vehicles,the article specifies the measuring method and mathematical model for indicating value errors in bourdon pressure gauge for railway locomotives and vehicles. It separately evaluates the uncertainty in measurement results when carrying out verification by using such two types of standard devices as digital pressure gauge and piston gauge,thus verifying the measurement reliability.
