Jumo India Pvt Ltd manufactures Pressure and Differential Pressure Switch for Air, Smoke and Flue Gases. Jumo India Pvt Ltd is DIN EN ISO 9001 and DIN EN ISO 14001 certified company. Pressure and Differential Pressure Switch for Air, Smoke and Flue Gases is manufactured as "Pressure and differential pressure switch for air, smoke and flue gases, polycarbonate case, up to 150 mbar". These pressure switches are used to measure vacuum, pressure or differential pressure in HVAC and filter technology. Pressure and differential pressure switches consist essentially of base, diaphragm, intermediate disc, case and protective cover. When used as pressure or vacuum switch, the base and diaphragm with disc form the pressure chamber. When used as a differential pressure switch, the base and a second diaphragm with intermediate disc form the two pressure chambers. A pressure change in the pressure chamber causes an axial displacement of a pin linked to the diaphragm. When the selected switching point is reached, a spring-loaded contact is activated.
