A lot of people don't know how to determine when choosing pressure gauge pressure gauge level of precision, also don't know how much is each level corresponding to the permissible error of precision. Don't try so hard, the instrument you know one by one! According to the provisions of the state, the precision of the pressure gauge level is divided into: 1. Level 0; 1. Level 6; 2. Level 5; 4. Level 0, all levels of instrument shell nominal diameter shall comply with the provisions of the table below: shell nominal diameter ( mm） Precision level 40; 602. 5; 4. 01001. 6; 2. 5150; 200; 2501. 0; 1. 6 and pressure gauge precision grade and allowed error and its relationship to comply with the provisions of the table below: precision grade permissible error % ( According to the range of percentage) Zero measurement limit ( 90 ~ 100) % the rest with the check pin without stop pin 1. 01± 1± 1. 6± 11. 6 ( 1. 5) 1. 6± 1. 6± 2. 5± 1. 62. 52. 5± 2. 5± 4± 2. 54. 04± 4± 4± 4 ( Note: the use of 1. Press 1 level 5 gauge permissible error. Level 6 calculation, accuracy level don't change it. ）
