Reliance Levalarms® Low Water Cut-Out and Level Switch Applications (clark-reliance)

Reliance Levalarms® are proven level alarm and cut-out solutions used to help protect boilers, tanks, and water-based process applications by providing dependable low-level switching. Westech Industrial supports the full Levalarm family across Canada—helping you select the right switch style (float, probe, or retrofit), certifications, and configuration for your application.

NEW: Levalarm 1000 Float Level Switch (REA100F-1000)

Designed for demanding services where vibration, high temperature, and installation realities can challenge traditional switching.

Key features

• Rated for pressures up to 1000 psi (69 bar)
• Performance is not impacted by heat, vibration, or loss of electrical power
• Positive interlocking operation using a dual-magnet approach
• Drop-in style installation with minimal commissioning adjustments

How it Works

A stainless-steel float actuates an internal magnet system that drives a secondary magnet in the switch housing to mechanically activate the switch. The repelling magnetic fields help provide a stable “locked” switching action that resists vibration and can help compensate for minor installation misalignment.

Levalarm® GOLD Float-Type Switch

• 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 new Levalarm GOLD switch represents a major step forward in reliability. It employs the same interlocking magnet operation used by Clark Clark-Reliance in its Jerguson Level Switches for over 28 years. Here’s how it works:

A stainless steel float is attached to the end of a rod with a stainless steel encapsulated magnet. The magnet travels vertically in the pressure tube. The primary magnet on the float rod inside the pressure tube drives the secondary magnet, which in turn drives the tertiary magnet. The tertiary magnet is mounted to the switch arm and activates the switch. The use of repelling magnetic fields create a positive interlocking switch that is vibration resistant.

A buoyed float will cause the reaction of the magnets to hold the switch open or closed, depending on which switch terminals are used. As liquid falls in the chamber, the float drops and directs the magnets to the opposite position which activates the switch in the opposite direction.

EA101 Probe-Type Level Switch (Series EA101)

For applications that prefer probe-based level switching and fast response.

Highlights

• For pressures up to 1800 WSP (124 bar)
• Suitable for boilers and tanks; commonly used in power and processing facilities
• Each unit monitors up to ~3 inches of level change; multiple units can be staged to extend range

Retropak Assemblies (EA100 retrofit to probe operation)

A practical upgrade path for legacy EA100 float-design installations.

Highlights

• For applications with EA100D / EA100S / EA100SW legacy switches
• Converts to probe operation to reduce maintenance associated with float mechanisms
• Installs without boiler piping modification (swap cover plate + probe assembly)
