　　Theme features:General pressure gauges are suitable for measuring the pressure of liquids, vapors, gases, and other media that are non explosive, non crystalline, non solidifying, and do not corrode copper and copper alloys

　　Working Principle:

The pressure gauge converts the elastic deformation of the Bourdon tube, a sensitive element inside the gauge, into rotational motion through the conversion mechanism of the movement inside the gauge, causing the pointer to deflect to display pressure.

Bourdon tubes are divided into C-shaped tubes, reed tubes, spiral tubes, and other types. Generally, cold work hardening materials (commonly copper alloys) are used, which have high plasticity in the annealed state. After cold work hardening and qualitative treatment, high elasticity and strength are obtained.

The cross-section of the C-type Bourdon tube sensitive element appears elliptical, and the pressure of the measuring medium acts on the inner side of the Bourdon tube, causing the elliptical cross-section of the Bourdon tube to tend towards a circular cross-section. Due to the slight deformation of the Boden tube, a certain amount of ring stress is formed. This ring stress will cause the Bourdon tube to extend outward. Due to the lack of fixation at the head of the elastic Boden tube, it will undergo slight deformation.
