 Model B40 High Temperature/High Pressure Service External Caged Liquid Level Switches   Printer Friendly Version
The B40 external cage liquid level switch is a float-actuated control specifically designed and constructed for high pressure, high temperature service conditions such as boilers. It is available in rugged industrial or ASME B31.1 construction.


Operating Principle Features Industries Options Downloads Approvals
 
As the counter weighted float follows liquid level changes, a magnetic sleeve is moved into or out of the field of a switch-actuating magnet causing switch operation. A non-magnetic barrier tube isolates the switch mechanism from the controlled liquid.
