Magnetic float level switch C24

displacerfor liquidsstainless steel

Models C24/C25, boiler, and water column liquid level switches are single- or multi-switch units that offer versatility and reliable operation in a variety of applications. Available with up to three switch mechanisms for level alarm, control, and shutdown functions, the boiler and water column controls are designed for use in steam boiler applications while the Models C24 and C25 are for general use. A permanent magnet is attached to a pivoted switch actuator. As the float/displacer rises following the liquid level, it raises the attraction sleeve into the field of the magnet, which then snaps against the non-magnetic enclosing tube, actuating the switch. The enclosing tube provides a static pressure boundary between the switch mechanism and the process. On a falling level, the float/displacer deactivates the switch.

This movement positions an attraction sleeve in the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
