How to determine the accuracy level of a pressure gauge?
The accuracy levels of the precision pressure gauges are 0.1, 0.16, 0.25 and 0.4 respectively. The accuracy levels of the general pressure gauges are 1, 1.6, 2.5 and 4 respectively. The method of selecting the accuracy level of the pressure gauge shall be based on the requirements of the production process, economic, practical and testing methods, and the accuracy grade shall be determined according to the allowable error of the minimum pressure measured. Precision class calculation method: the actual error value / actual range * 100% out of the figures, remove the number, get the number close to the above numerical value, the accuracy level is how much
You can check the manual according to the model, or you can look at the label on the pressure gauge, but the most reliable method is to do the verification
Under the dial of the pressure gauge, there is a level of accuracy corresponding to the current table. The common grades are 0.4, 1, 1.6, and 2.5.You can check the pressure gauge standards manual according to the type.You can send the pressure gauge to the third party inspection unit for inspection, and a grade report will be made according to the corresponding data.
