Diaphragm pressure gauges are one of the more common types of industrial pressure gauges. They consist of a standard pressure gauge of a certain type, combined with a separator that meets specific requirements. The separator is made up of a connecting element and a diaphragm. This combination enables the measurement of pressures in media that are highly corrosive, viscous, at high temperatures, or contain solid particles that tend to solidify. Diaphragm pressure gauges are widely used in the production processes of industries such as petrochemicals, soda manufacturing, steel, food, chemical fibers, and dye and pharmaceutical manufacturing, for measuring the pressure of fluid media. If we need to measure the pressure of ordinary gases, water, and oils, a regular pressure gauge is usually used. When measuring the pressure of nitric acid, phosphoric acid, or strong alkalis, stainless steel pressure gauges are more commonly employed. However, when the medium being measured is highly corrosive (such as hydrochloric acid, wet chlorine gas, or ferric dichloride), or when it is a medium with high viscosity (such as latex), one that tends to crystallize (such as saltwater), solidify (such as hot asphalt), or contains solid particles (such as sewage), it is not feasible to use the aforementioned pressure gauges. This is because even SUS316 stainless steel tubes can be corroded by hydrochloric acid, and the particles in asphalt and sewage can easily block the pressure sensing holes of the pressure gauge, rendering it unusable. At this point, it is necessary to choose a diaphragm pressure gauge. Diaphragm pressure gauges can use different types of corrosion-resistant diaphragm materials depending on the highly corrosive media involved, thereby providing corrosion protection. Thanks to the diaphragm, it prevents high-viscosity, crystalline, or easily solidifying media from entering the pressure sensing hole, ensuring the proper operation of the instrument. Therefore, diaphragm pressure gauges are widely used in industrial sectors such as petrochemicals, metallurgy and power generation, as well as food and pharmaceuticals, for measuring pressures during production processes.
