Bellows pressure gauge, is a measuring instrument, small pressure is measured at about standard atmosphere pressure instrument. It is mainly applied to boiler ventilating, gas pipeline, burning device and other similar devices. Constitute part of the bellows pressure gauge are: measurement system ( Including joints, corrugated box, etc. ) And drive mechanism ( Including the pull rod, gear transmission mechanism) , indicating device ( Including the pointer and dial) And the shell ( Including watchcase, lining and table cover glass or PC) 。 Bellows pressure gauge working principle: based on the corrugated bellows under the effect of pressure measured medium, the free end produce elastic deformation, then through and amplification, transmission gear transmission mechanism by pointer fixed on gear shaft by measured values will be indicated on the dial out. So you can know the location of the pressure.
