Vibration proof pressure gauge precision grade 1.6 and 1.5 difference
The accuracy level of a pressure meter refers to the percentage of the allowable error of the pressure gauge to the full scaleFor example, a pressure gauge full scale is 100Mpa, the accuracy level is 1.6, then its allowable error is 100Mpa * 1.6%= + 1.6Mpa., if the accuracy level is 1.5, then its allowable error is 100Mpa * 1.5%= + 1.5Mpa.According to the current national standard GB/T1226-2001, "general pressure table", the accuracy level is 1.6, the use of 1.5 pressure gauges allowed error by 1.6 levels, the accuracy level can not be changed
The 1.5 level is the old national standardThe 1.6 level is the new national standard
