 High Pressure External Caged Liquid Level Switches   Printer Friendly Version
Displacer actuated external cage liquid level switches are external cage units that utilize a single switch mechanism for level alarm or control functions in higher pressure applications.
Operating Principle Features Industries Options Downloads Approvals
 
Liquid level movement changes the buoyancy force on a displacer suspended from a range spring. The force change on the spring causes it to extend or compress, moving an attraction sleeve into or out of the field of the switch magnet, actuating the switch.
