Pressure gauges are widely used in almost all industrial processes and scientific research fields. The working principle of a pressure gauge is to use the elastic deformation of sensitive components (Bourdon tube, bellows, bellows) inside the gauge, and then transmit the pressure deformation to the pointer through the conversion mechanism of the movement inside the gauge, causing the pointer to rotate to display pressure.

So the movement of the pressure gauge is very important for the pressure gauge, as it can ensure the accuracy of the pressure gauge.

The pressure gauge movement consists of a central gear, a sector gear, a balance spring, an indication adjustment screw, and a connecting rod.

The pressure gauge movement can convert the linear displacement of the free end of the spring tube into angular displacement, amplifying the small displacement of the spring tube and allowing the pointer to obtain a larger angle proportional to the measured pressure, ensuring sufficient reading accuracy of the pressure gauge and achieving the purpose of easy observation of the indicated value.

The pressure gauge movement is the main working object in pressure gauge maintenance. It is the root cause of pressure gauge faults and errors. Maintenance personnel should have a full understanding of it in order to successfully complete the maintenance tasks.
