Element ELT-4 Three Phase Mechanical Pressure Switch
Based on the industrial design and engineering standards of the Element control series, the Element ELT 4 is a heavy duty mechanical pressure switch built for regulating the automatic operation of three phase industrial air compressors, booster systems, and hydrophore water pumping equipment. Acting as a robust, non digital line controller, it mechanically cycles high power three phase motor loads directly by monitoring the fluid or gas pressure thresholds inside an connected pressure vessel or pneumatic line.
Key Features
-
High Capacity Multi Phase Contact Interrupter: Features a robust internal three phase contact mechanism designed to securely break or connect high current motor pathways without requiring an intermediate control relay.
-
Integrated Manual ON/OFF Safety Toggle: Outfitted with an external 2 position manual toggle lever at the base of the plastic housing, allowing operators to safely isolate the pump or compressor system during standard maintenance or emergencies.
-
Heavy Duty Protective Enclosure: Covered by an impact resistant, thick matte plastic canopy that completely seals the internal micro switch contacts and calibration springs against industrial airborne particles, dust sifts, and moisture drops.
-
Heavy Aluminum Die Cast Base Manifold: Built upon a durable metallic connection manifold containing standard female threaded connection ports, ensuring airtight integration onto receiver tanks, air loops, or heavy plumbing fittings.
-
Adjustable Operational Setpoints: Designed with internal spring loaded adjustment screws located beneath the cover canopy, giving technicians the ability to field calibrate both the cut in (system start) and cut out (system stop) pressure values.

Applications
-
Industrial Air Compressor Automation: Directly manages heavy duty three phase piston or screw type air compressors by automatically turning the motor off when the air receiver reaches peak storage capacity, and restarting it as air tools consume the reserve.
-
Commercial Building Water Booster Stations: Regulates large multi phase booster pumps inside high rise facilities or commercial infrastructure to maintain a reliable water flow across plumbing networks.
-
Agricultural Hydrophore Systems: Installed onto deep well water extraction reservoirs to monitor fluid pressure loops, preventing excessive pressure stress on distribution pipelines.
-
Pneumatic Machinery Safety Systems: Serves as a reliable, non electronic mechanical fallback to prevent system over pressurization inside industrial pressure vessels and processing plants.
