Analog pressure gauge

Factory outlets no intermediate links, give customers more profit space, to seek long-term cooperation and look forward to your calls. ◆ detailed technical parameters, features, functionality and price, please call us: Contact: Manager Yang, Liu stainless steel differential pressure gauge for measuring small differential pressure between two high-pressure source in the industrial process control. Such as: the filter pressure loss and working conditions; pressure loss pipe network; valves work status. Differential pressure gauge stainless steel structure for the 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" were shaped stents activities 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 the end of the rod through the activities connected with the stent; dial directly fixed to the gear mechanism. When the upper and lower ends received 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 zoom by differential pressure value indicated by the pointer deflection.
