The use grade range is Exd II CT6. Imported explosion-proof pressure switches must pass UL, CSA, CE and other international certifications. It can be used in explosive areas and strong corrosive atmosphere environments. Flameproof pressure switches are available in different pressure, differential pressure, vacuum and temperature ranges. Common applications include electric power, petroleum, chemical industry, metallurgy, boiler, food machinery, environmental protection equipment and other industries.
