What are the pressure gauge specifications

What are the pressure gauge specifications? Let's introduce it to you:

The nominal diameter of the pressure gauge housing (mm) is: ￠40, ￠50, ￠60, ￠100, etc.

Pressure gauge structure forms are: radial, axial, axial belt front, radial belt back, radial belt front, etc.

China's general industrial pressure gauge is divided into four accuracy J, precision J are: 1.0J, 1.6J, 2.5J, 4.0J;

The selection of the precision J of the pressure gauge should be based on the allowed large J pair error of the process production and the selected instrument range, and the allowed large reference error of the instrument should be calculated, and the accuracy of the instrument should be determined in the specified precision J. In general, the more accurate the instrument selected, the more accurate and reliable the measurement results. However, it cannot be considered that the higher the accuracy of the selected instrument, the better, because the more accurate the instrument is generally more expensive, and the more difficult the operation and maintenance.
