Madison M7000 Miniature Liquid Level Switch Spst 1/8 in

Product Description

The MADISON M7000 is a miniature liquid level switch designed for monitoring fluid levels in systems handling fuels and lubricating oils. Built with a 1/8-inch thread connection and rated to a maximum of 150 psi, this switch is engineered for demanding industrial and mechanical environments where precise, compact level sensing is required. The SPST switch logic provides a straightforward single-pole, single-throw circuit action. Rated for up to 105 degrees F, the M7000 suits applications where fluid temperature remains within moderate operating limits. Licensed technicians and mechanical service professionals handling fuel system maintenance and fluid management installs will find this unit well suited to their work.

The M7000 is intended for use in systems containing fuels and lubricating oils, making it applicable across light industrial, fleet maintenance, generator service, and mechanical equipment contexts. Its miniature form factor and threaded connection allow installation in tanks, reservoirs, and fluid vessels where space is limited. The 1-inch float diameter and 0.45 float specific gravity are matched to the density range of common petroleum-based fluids, ensuring reliable float actuation under normal operating conditions.

Key Features

• SPST switch logic for straightforward open/close level detection
• 1/8-inch thread connection for compact, direct tank or reservoir mounting
• 150 psi maximum pressure rating suits pressurized fluid systems
• 105 degrees F maximum temperature rating appropriate for fuel and oil service
• 1-inch float diameter with 0.45 float specific gravity calibrated for petroleum-based fluids
• Dual voltage compatibility: 120V AC and 240V AC

Compatibility

Designed for use with fuels and lubricating oils in systems requiring miniature liquid level switching with a 1/8-inch threaded connection and SPST logic.

Installation Notes

Installation is typically performed by a licensed mechanic, electrician, or qualified service technician familiar with fluid system instrumentation. Power down and de-pressurize the system before removing or installing the switch. Verify thread compatibility and apply appropriate thread sealant to prevent leaks at the connection point. Follow all applicable electrical codes when wiring the switch into the control circuit.
