Measurement Principle:
The buoyancy force of a process liquid on the float causes the float to move with the liquid surface. The movement of the float moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
Features:
Easy access to internals through flanged float chamber
Process temperature to +750° F (+399° C)
Multiple switch capability
Working steam pressure to 600 pounds
Cast iron or fabricated steel float chambers
316 and 316L stainless steel floats
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
Boiler low water cut off
Options:
Choice of switch mechanisms: mercury, hermetically sealed, dry contact, or pneumatic
