Precision pressure gauge manufacturers can achieve precision 0.05 pressure gauges?

Answer:

Precision pressure gauge manufacturers can achieve accuracy of 0.05 pressure gauges.Accuracy class1. The accuracy level of the pressure gauge reflects the accuracy of the comparison between the check table and the precision meter. The indication value is close to the true value. It is equal to the percentage of the maximum absolute error and the upper limit of the measurement limit, which is determined by the magnitude of the error in the calibration.2, China's general industrial pressure meter is divided into 4 accuracy levels, in line with JJG52-1999 "Bourdon tube general pressure gauge, pressure vacuum table and vacuum meter" verification regulations, the pressure table prepared by the allowable error. These 4 levels of accuracy are: 1, 1.6, 2.5, and 4. Allowable error (calculated according to the percentage of the upper limit of measurement) is 1%, 1.6%, 2.5%, 4%, respectively.3, China 2005 new digital pressure gauge verification regulations promulgated and implemented, in line with JJG875-2005 "digital pressure gauge verification regulations.". The accuracy of the pressure is respectively 0.01%, 1.6%, 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, 1%, and so on.4, the method of selecting the accuracy level of the pressure gauge should be based on the requirements of the production process, economic, practical and testing methods, and the accuracy grade should be chosen according to the allowable error of the minimum value of the measured pressure.

According to the JJG49-1999 spring tube precision pressure gauge and vacuum meter verification regulation, the accuracy degree of the pointer precision pressure gauge is:0.6, 0.4, 0.25, 0.1, 0.06The accuracy of the digital table is followed by 2.5, 1.6, 0.5, 0.4, 0.2, 0.1, 0.05

The accuracy of the digital table is followed by 2.5, 1.6, 0.5, 0.4, 0.2, 0.1, 0.05
