Levalarms® Low Water Cut-Out and Level Switch Applications

• For Pressures up to 1000 psi (69 Bar)

• Zero effect from heat, vibration or loss of electrical power

• Positive interlocking magnet design – proven over 30 years of use

• Drop-in design requires no adjustments to commission

The Levalarm REA100F-1000 float switch represents a major step forward in reliability.  It employs a robust dual magnet design with a positive interlock.

A stainless-steel float is attached to the end of a rod with a stainless-steel encapsulated magnet. The float magnet pivots vertically on an axle inside the chamber. The 
primary magnet on the float rod drives the secondary magnet located inside the switch housing. The secondary
magnet movement causes a physical activation of a switch.

The use of repelling magnetic fields creates a positive interlocking switch that is both vibration resistant and compensates for installation misalignment. A buoyed float will cause the reaction of the magnets to hold the switch open or closed, depending on which terminals are used.

As liquid falls in the chamber, the float drops and directs the magnets to the opposite position which activates the switch.
