Madison M5010 Liquid Level Side-mounted Switch 300 Psi

Product Description

The MADISON M5010 is a side-mounted liquid level switch engineered for demanding industrial and process environments. It operates at pressures up to 300 psi and temperatures up to 200 degrees F, making it suitable for high-pressure, high-temperature, and corrosive service conditions. The switch uses a float with a 0.6 specific gravity and a 1.125-inch float diameter, and features SPST (single-pole, single-throw) logic for straightforward on/off level detection. The stainless steel body provides corrosion resistance in aggressive media. Licensed technicians and instrumentation professionals install this switch in tanks, vessels, and process lines where reliable level sensing is critical.

The M5010 is designed for applications involving high-temperature fluids, elevated system pressures, and chemically corrosive conditions. It is well-suited for use in process piping systems, industrial tanks, and HVAC hydronic equipment where conventional plastic or brass float switches would not survive. The 3/8 in - 24 threaded connection allows side-mounting directly to a vessel wall or tapped fitting. Rated at 120V ac and 240V ac with a 30W resistive load capacity, it integrates into standard control circuits without additional conditioning hardware.

Key Features

• Rated to 300 psi maximum operating pressure
• Maximum temperature rating of 200 degrees F for high-temp service
• Stainless steel body construction for corrosive and harsh media compatibility
• SPST switch logic for direct integration into on/off level control circuits
• 1.125-inch float diameter with 0.6 float specific gravity for reliable actuation
• Dual voltage rating: 120V ac and 240V ac

Compatibility

Designed as an OEM-style side-mounted float switch replacement for industrial tanks, process vessels, and high-pressure piping systems requiring a 3/8 in - 24 threaded side-mount connection.

Installation Notes

Installation is performed by licensed instrumentation technicians, plumbers, or qualified HVAC mechanics. De-energize the control circuit and depressurize and drain the vessel or piping before removing or installing the switch. Use appropriate thread sealant rated for the service temperature and media on the 3/8 in - 24 threads. Verify float orientation and float specific gravity compatibility with the process fluid before commissioning.
