Siemens QPD15.010 Differential Pressure Switch model_skp15_012u1 Air flow rate at ˆThe QPD differential pressure switches are used for monitoring air pressures and air flows. When the pressure falls below or exceeds the adjusted switching point, the respective electrical circuit will be opened or changes over. Specifiactions: For the supervision of air pressures or air flows of oil or gas fired equipment (burners, boilers, furnaces) QPD15 are suitable as absolute or differential pressure Adjustable working pressure ranges up to 5
