1. The accuracy level of the pressure gauge reflects the degree of accuracy of the indicated value being close to the true value in the comparison between the tested gauge and the precision gauge. It is equal to the percentage of the ratio of the absolute value of the maximum basic error to the upper limit of the measurement, which is determined according to the size of the error generated in the calibration.
2. China's general industrial pressure gauges are divided into 4 accuracy levels, which are in line with the allowable error of the pressure gauge drawn up by the JJG52-1999 "spring tube type general pressure gauge, pressure vacuum gauge and vacuum gauge" verification regulations. The 4 accuracy levels are: Level 1, Level 1.6, Level 2.5, Level 4. The allowable errors (calculated as a percentage of the upper limit of measurement) are ±1%, ±1.6%, ±2.5%, and ±4%, respectively.
3. In 2005, China's new digital pressure gauge verification regulations were announced and implemented, in line with JJG875-2005 "Digital Pressure Gauge Verification Regulations". The specified pressure accuracies are ±0.01%, ±0.02%, ±0.05%, ±0.1%, ±0.2%, ±0.5%, ±1.0%, ±1.6%.
4. The method of reasonably selecting the accuracy level of the pressure gauge should be based on the requirements of the production process, economy and practicality, testing methods, etc., and the accuracy level should be selected according to the allowable error required by the minimum value of the measured pressure.
