Pressure gauge refers to an instrument with elastic element as sensitive element, which measures and indicates the pressure higher than the environment.
The pressure gauge consists of pressure guide element, gear transmission element, indicator and shell. Pressure gauges are widely used in almost all industrial processes and scientific research fields.
The pressure gauge displays the pressure through the elastic deformation of the sensitive elements (Bourdon tube, diaphragm and bellows) in the meter, and then the pressure deformation is transmitted to the pointer by the conversion mechanism of the movement in the meter, which causes the pointer to rotate.
