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.

Features

  • miniature floating switches feature a floating probe to detect high / low levels in a container.
  • These polypropylene switches are ideal for low-temperature food equipment, agriculture applications, or contact with many industrial fluids.
  • They can be installed in a vertical or horizontal position for the user's convenience and can withstand a maximum temperature of 392 degrees F.
  • They come with field-adjustable stem lengths that can be extended with pipe to meet custom tank / container depth.
  • Multi-level float switches control multiple switch points, pumps & valves, warning alarms and many more.
  • These versatile switches are available in polypropylene / Buna N / 316 SS float material to cater to varied applications.

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.
