The role of pressure gauge movement

Pressure gauge application widespread, it almost throughout all of the industrial process and research fields. The working principle of pressure gauge is a sensitive element (by table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. So the machine core is very important for pressure gauge pressure gauges, it can guarantee the accuracy of the pressure gauge. Pressure gauge movement by the center gear, gear sector, balance spring, value adjustment screw, connecting rod, etc. Pressure gauge movement spring tube can be free of the linear displacement to angular displacement, tiny displacement of spring tube amplifier, so that a pointer for the larger Angle of proportional to the measured pressure and to ensure that the pressure gauge has enough accuracy of reading, to achieve the purpose of easy observation indicated value. Pressure gauge movement is the main pressure gauge repair work object, it is the root cause of pressure gauge malfunction, causing errors, maintenance staff to he should have full understanding, to successfully complete overhaul of the task.
