The pressure gauge series is complete. It has not only conventional series, but also digital series; not only common medium application series, but also special medium application series; there are not only switching signal series, but also remote transmission signal series, etc. The pressure gauge transmits the pressure deformation to the pointer through the elastic deformation of sensitive elements (Bourdon tube, bellows and bellows) in the gauge and the conversion mechanism of the movement in the gauge, so that the pointer rotates to display the pressure. The pressure gauge comprises an overflow hole, a pointer, a glass panel and the like.

When the watchcase of manometer was assembled, the equipment operation of equipment was more troublesome, needs the staff to set up the adjustment many times, needs to stop the equipment operation midway, leads to the watchcase packaging efficiency of manometer to it is inconvenient to change to the used mould of watchcase size of manometer.
