Performance and characteristics of precision pressure gauge

Precision pressure gauges are widely used in petroleum, chemical, chemical fiber, metallurgy, power station, food and other industrial sectors to measure the pressure of various fluid media in the process flow that requires high corrosion resistance and high temperature resistance.
The table uses direct contact joints and pressure-sensitive component materials, icr18Ni9T, Ocr18Ni12Mo2Ti, sus316, the structure is fully sealed, stainless steel pressure gauge has a strong ability to prevent the measured medium corrosion and environmental corrosion. The stainless steel pressure gauge is suitable for the medium with strong corrosiveness suitable for the detection of stainless steel components and the harsh external corrosion environment. The stainless steel pressure gauge is widely used in petroleum, chemical, metallurgy and other industries.
The working principle of the instrument: Based on the pressure-sensitive element, two bellows with the same stiffness are used, so they are forced to produce the same concentrated force on the movable bracket under the same measured medium, because the spring blades are under the same moment on both sides There is no deflection, so the bracket is still in the original position, so the gear transmission mechanism does not move, the pointer is still at the zero position. When different pressures are applied (generally the high-pressure end is higher than the low-pressure end), the forces of the two bellows acting on the movable bracket are not equal, so that the corresponding displacements are generated, and the gear transmission mechanism is driven to drive and enlarge, after the pointer is deflected Indicates the differential pressure value between the two.
The stainless steel pressure gauge is composed of a pressure guiding system (including joints, spring tubes, current-limiting screws, etc.), a gear transmission mechanism, a counting device (pointer and dial), and a housing (including a watch case, watch cover, watch glass, etc.).
The pressure gauge passes the elastic deformation of the stainless steel sensitive elements (Bourdon tube, bellows, bellows) in the table, and then the conversion mechanism of the movement in the table transmits the elastic deformation to the pointer, causing the pointer to rotate to display the pressure.
