Magnetrol Models C24 & C25 Boiler and Water Column Liquid Level Switches

$ 1,660.25

Description:  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 & C25 are for general industrial 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.

Applications: 

  • Condensate receiver control
  • Flash tank high level alarm
  • Water tube boiler low water cutoff
  • Boiler steam chest high level alarm
  • Boiler feedwater pump control
  • Day tanks
  • Boiler low water cutoff
  • Holding tanks

Features:

  • Easy inspection of float chamber through removable head
  • Cast iron or fabricated steel float chambers
  • 316 and 316L stainless steel floats
  • Brass chamber liner standard in Models B24, B25, W24 and W25
  • Right or left hand water column mounting
  • Process temperature to +1000º F (+538º C)
  • Working steam pressure to 600 pounds

Options:

  • Dry contact, hermetically sealed or pneumatic switch mechanisms
  • Choice of switch enclosure
  • Try-cock and sigh glass tappings
  • Right or left hand water column mounting
  • High temperature insulation available
