differentialrelativeSPDT

Version: relative and differential pressure Case: Coated steel Sensing element: » NBR, FKM or EPDM diaphragm, aluminium alloy flange Switch: 1 or 2 change over (SPDT) Options: » Intrinsic Safety Uses Specially produced for AIR and GAS control of burners, these pressure switches are also suitable for the control and monitoring of any low or very low pressure and suction such as ventilation, draught, pressurisation, etc.Differential pressure units are generally used for flow control of non corrosive gases. A typical example is the indication of air or gas filter fouling.
