MADISON Liquid Level Switches

Point-level float switches featuring reed switch technology to externally control an alarm or an ON / OFF switch and field-adjustable stem lengths (on selected models) for using just one sensor in multiple drums. Available in close-on-rise & open-on-rise configurations

Filter

Madison liquid level switches regulate and monitor the oil or water level in a container. These units float on the top of the liquid surface and notify users when the liquid surface goes up or down. They are used in pumps, valves or alarms.

Frequently Asked Questions

What is the purpose of the float level sensor?

These continuous level sensors feature a magnetic float that can rise and fall as liquid levels change. The float movement creates a magnetic field that actuates a hermetically sealed reed switch (located in the stem of the liquid sensor), thereby triggering the switch to open / close.

What are side mount level switches used for?

The side mount level switches can rotate 180 degrees and monitor liquid rise or fall in a tank. These encapsulated, magnetically coupled dry reed units can deliver more than 5 million switching cycles to control motor starters, solenoids, contractors and relays.

What is the advantage of polypropylene in Madison level switches?

Polypropylene is a type of synthetic resin that is moulded or extruded for making floating switches, providing toughness, flexibility and heat resistance.
