Magnetrol B25-1B10-KOE C24, c25, boiler and water column liquid level switch Datasheet

C24, C25, Boiler
and Water Column
Liquid Level Switches
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.
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 B24, B25, W24, and
W25 models
• Right or left hand water column mounting
• Try cock tappings and sight glass tappings available
• Process temperature to +1000° F (+538° C)
• Multiple switch capability
• Working steam pressure to 600 pounds
APPLICATIONS
• Choice of switch mechanisms:
Pneumatic
Hermetically sealed
Dry contact
• Flash tank high level alarm
• Choice of switch mechanism enclosures:
• Water tube boiler low water cutoff
• Condensate receiver control
NEMA 1 carbon steel for pneumatic
• Boiler steam chest high level alarm
TYPE 4X/7/9 Class I, Div. 1, Groups C & D,
polymer coated aluminum
• Boiler feedwater pump control
• Day tanks
TYPE 4X/7/9 Class I, Div. 1, Group B,
polymer coated aluminum
• Optional high temperature insulation available.
See bulletin 41-106.
• Boiler low water cutoff
• Holding tanks
TECHNOLOGY
A permanent magnet is attached to a pivoted
switch actuator and adjustment screw . As the
float 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, an inconel spring retracts the
magnet, deactivating the switch.

The right- and left-hand mounting arrangement refers to
the position of the try cock tappings in relation to the
gauge glass connections.
Model W24—Right-hand mounting
Model W25—Right-hand mounting
Model W29—Left-hand mounting
To determine whether the control mounting is right- or
left-hand, position the control with the gauge glass connections facing you. If the try cock tappings are to the
right, it is a right-hand control, if they are to the left, it is
a left-hand control. Refer to illustrations below.
