C24, C25, BOILER AND WATER COLUMN LIQUID LEVEL SWITCHES


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.

Operating Principle


The buoyancy force of a process liquid on the float causes it to move with the liquid level change. This movement positions an attraction sleeve in the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
