Switches
Switches are available for water flow, air flow and air differential pressure.
Water Flow Switch
Indicates the presence or absence of water flow to start and stop electrically
operated equipment when a flow or no flow condition occurs. It is particularly suitable for air-conditioning plants, sprinkler systems, anti-fire system, steam boilers and heat pumps.
Air Flow Switch
Indicates the presence or absence of air flow to start and stop electrically
operated equipment when a flow or no flow condition occurs. It is particularly suitable for air-conditioning plants, general industrial plants and ventilation systems.
Air Differential Pressure Switch
Air differential pressure switch with a potential free changeover contact is used to detect the status of pressure drop across the filters. It’s N/O contact is connected to neon lamp to indicate the ‘filter dirty’ status. This silicone diaphragm type with calibrated adjustment knob facilitate pressure setting suitable for operation over a wide range of temperature from -20o C to 85o C, with a maximum operating pressure of 50 mbar.
