Pressure gauge movement is one of the key parts

In the structure of the pressure gauge, a comparison is one of the key parts movement. Pressure gauge movement by the center gear, gear sector, balance spring, value adjustment screw, connecting rod, etc. Movement of the main parameters include modulus, transmission ratio, balance spring torque, suitable pressure range. 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.
