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.
