Element ELT-3 Three-Phase Mechanical Pressure Switch

The Element ELT-3 is a heavy-duty mechanical pressure switch designed to control the automatic startup and shutdown cycles of three-phase industrial electric motors powering air compressors and water booster stations. It operates by mechanically making or breaking direct line connections when predefined high-pressure ceilings or low-pressure floors are crossed within a connected fluid or pneumatic closed loop.

Key Features

High-Insulation Operational Range: Explicitly engineered for high-power three-phase distribution manifolds with an explicit operational insulation rating of 400 V.
Industrial-Grade Working Pressure Window: Optimized to handle heavy machinery requirements across a working range of 3 to 11 Bar.
Manual ON/OFF Isolation Lever: Features a prominent red mechanical turn-knob located at the base of the cover. This allows field operators to quickly force-stop the system or cut power during maintenance routines.
Robust Multi-Port Manifold Base: Features an aluminum die-cast base fitting with robust mechanical nuts and input channels designed for heavy plumbing connections and pneumatic receiver line layouts.
Heavy-Duty Protective Enclosure: Covered by a thick, impact-resistant matte black plastic shroud that keeps industrial grime, dust, and water sprays out of the internal mechanical calibration springs and electrical contacts.

Applications

Heavy-Duty Piston & Rotary Screw Compressors: Controls industrial air receivers, automatically stopping the compressor pump when pressure peaks at 11 Bar and restarting it when levels drop toward 3 Bar.
High-Rise Building Water Booster Systems: Placed on centralized distribution manifolds to regulate multi-phase booster pumps, ensuring adequate water pressure across all facility floors.
Agricultural Irrigation Networks: Manages deep-well submersible water pumps by maintaining line pressures within optimal parameters, preventing over-pressurization pipes.
Commercial Hydrophore Tank Installations: Acts as a direct mechanical sensor to cycle water storage pressure vessels, maintaining necessary system equilibrium without digital control interfaces. Use Rule 1.
