Stainless steel differential pressure gauge

Use stainless steel pressure gauge instructions CYW-152B and CYW153B stainless steel pressure gauge [1] (hereinafter referred to as instruments) measurement of various liquid (gas) applies to process chemicals, of solder, metallurgy, electric power, nuclear power and other industrial sectors Medium for differential pressure, flow and other parameters. All meter structure made of stainless steel, which measurement system (dual bellows urgent connecting members), pilot pressure system (including joints, pipes, etc.) using reasonable special structure design, advanced technology, with small size, light weight, good stability , long service life, the appearance of new, adaptable and so on. Meter joint connection in the form of parallel type (which can be directly connected with three valves) and oblique two, able to adapt to different customers supporting the installation. Meter stainless steel pressure gauge structural principle of double bellows structure, namely two bellows were installed in a symmetrical position "I" shaped brackets on either side. The upper and lower ends of "workers" shaped the rack activities respectively and fixed ends, in the middle are connected by a spring sheet; low two bellows joints on the case is connected to a gear transmission structure mounted directly on the fixed end bracket. And is connected through the rod end of the bracket activities; dial directly fixed to the gear mechanism. When applied to different pressures (generally higher than the high-pressure side low side), two bellows acting on the movable support force is not equal to a displacement generated respectively, and drive transmission gear mechanism and to enlarge, after deflection by the pointer indicates differential pressure value.
