Element ELT-2 Three-Phase Mechanical Pressure Switch

The Element ELT-2 (manufactured under license/co-branding engineering pipelines often distributed alongside technical control setups) is a heavy-duty mechanical pressure control switch engineered to regulate the automated start-stop cycles of three-phase industrial air compressors and water pumping stations. By monitoring fluid or gas pressures within an isolated circuit, this mechanical switch breaks or makes direct high-current power connections to motor starters when pre-configured system pressure boundaries are reached.

Key Features

High-Capacity Three-Phase Switching: Outfitted with heavy-duty internal electrical contacts designed to safely cycle three-phase motor loads directly without triggering premature arc degradation.
Integrated Manual ON/OFF Toggle Switch: Designed with a prominent, red manual rotary lever on the lower corner of the plastic housing, allowing service technicians to cut power to the pump or compressor system during mechanical maintenance.
Rugged Aluminum Die-Cast Base Assembly: Built onto a sturdy metallic manifold block featuring standard female threaded entry ports for integration into pneumatic tank receiver fittings or hydraulic lines.
Impact-Resistant Protective Cover: Housed inside a thick, matte-black composite canopy shell that protects internal calibration springs and electrical contact points from dust, moisture, and factory debris.
Adjustable Range & Differential Springs: Features adjustable internal hex-nut springs under the canopy to customize the cut-in (start) and cut-out (stop) pressure setpoints to meet specific industrial requirements.

Applications

Industrial Piston & Screw Air Compressors: Installed on air receiver tanks to automatically turn off the compressor pump motor when the tank reaches maximum pressure capacity, and restart it when air pressure drops.
Water Booster Pump Systems: Regulates multi-phase water distribution pumps in commercial buildings or agricultural irrigation setups, maintaining steady system pressure within water storage reservoirs.
Factory Pneumatic Network Stations: Serves as a localized pressure monitor to manage auxiliary reserve tanks, ensuring tools and assembly line actuators receive constant, stable pressure.
Autoclave and Pressure Vessel Controls: Acts as a mechanical safety loop fail-safe to cut off heating or pumping elements if internal vessel pressure exceeds predefined factory limits. Use Rule 1.
