C24, C25, Boiler and Water Column Liquid Level Switches - 2

TECHNOLOGY A permanent magnet ➀ is attached to a pivoted switch actuator and adjustment screw ➁. As the float ➂ rises following the liquid level, it raises the attraction sleeve ➃ into the field of the magnet, which then snaps against the non-magnetic enclosing tube ➄, actuating the switch ≈. The enclosing tube provides a static pressure boundary between the switch mechanism and the process. On a falling level, an inconel spring retracts the magnet, deactivating the switch. MOUNTING WATER The right- and left-hand mounting arrangement refers to the position of the try cock tappings in...
