Product application: bellows pressure gauge is also called the micro pressure gauge. 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.

 

Instrument by measuring system (including joints, corrugated box, etc.), the transmission mechanism (including the pull rod, gear transmission mechanism), indicating device (including a pointer and dial) and the shell (including casing, lining and table glass). 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.
