The general knowledge of the bellows pressure gauge

Bellows pressure gauge is also a pressure meter is commonly used in industrial production, the production has played a very important role. Bellows pressure gauge is also called the micro pressure table. Suitable for measuring the explosion danger, crystallize, solidify, as well as to the copper and copper alloy non-corrosive effect of low pressure liquid, gas or steam. Bellows bellows pressure gauges used as a measurement of tiny pressure sensitive element. Measure the corrode the copper alloy, no explosion danger the micro pressure and negative pressure of the gas, widely applied to boiler ventilating, gas pipeline, burning device and other similar devices. The structure and principles of bellows pressure gauge is: instrument by measuring system ( Including joints, corrugated box, etc. ) , transmission mechanism, Including the pull rod, gear transmission mechanism) Indicating that the parts ( Including the pointer and dial) And the shell ( Including the watch case, glass lining and table) . The operation principle of the instrument is based on the corrugated bellows under pressure measured medium, its free end produce elastic deformation, then through and to amplify the transmission gear transmission mechanism, the fixed on the shaft of the pointer will be measured by value on the dial indicator. And zero device, can easily adjust the zero.
