Bellows pressure gauge has a name, that is, micro pressure tables, as the name implies, is a measuring instrument, small pressure is measured at about standard atmosphere pressure instrument. 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 the watch case, glass lining and table) 。 Know that part, and then to know about the working principle: based on the corrugated bellows under the pressure of measured medium, 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. Bellows without pressure gauge widely the application scope of pressure gauges, it is mainly applied to boiler ventilating, gas pipeline, burning device and other similar devices. But because the production of bellows pressure gauge material is qualitative different, so for the installation location of the surrounding environment is not the same. General bellows pressure gauge production material has two kinds, one kind is copper or copper alloy, the other is a stainless steel material. Copper alloy bellows pressure gauge around the installation is the requirement of environment, no explosion danger, measurement of material not crystallize, solidification, and is to be for copper and copper alloy no corrosive action of liquid, gas or steam of low pressure. Stainless steel bellows pressure have no so many requirements, due to the corrosion resistance of stainless steel materials, stainless steel bellows pressure gauge can be used in the corrosion process of high demand. Through the working principle and application of bellows pressure gauge, when everyone in the choice of more accurate can choose what you want me, pressure gauge.
