  • Float Switches

    Optical sensors, tilt-float switches & conductivity switches ideal for use with semi-solid liquids, slurries or oil in high / low level alarm triggers, overflow or spill containment vessels and pumps. Feature a polypropylene / EPDM float that can withstand a max. temperature of 221 degrees F

  • Flow Rate Sensors
  • Noncontact Level Sensors

    Continuous-level ultrasonic sensors providing non-contact fluid level measurement of semi-solid, viscous & corrosive media in close / open channel flows. Feature a self-cleaning sensor face with the capacity to filter out false echoes & a temperature compensated signal for better accuracy

About Madison

The company's product catalogue includes switches, floats, indicators and sensors. Madison float switches are used to measure liquid levels using sensors with an electrical contact output. They are also available in optical & conductivity sensor variants that can withstand extreme temperatures, pressures and vibrations. Liquid level switches by Madison feature a high-level alarm and are used in liquid control systems to prevent the spill & overflow of fluids. The brand's tape level indicators use a magnetic float to read liquid level. They are widely used in drums and storage tanks.

Madison Competitive Advantages

Miniature Continuous Float Level Sensors

They are designed for monitoring dispensed agricultural fertilisers & high-value chemicals, tank level monitoring and lubrication applications. These sensors are capable of fitting into small tanks (4 - 5 inches). The compact physical dimensions of the float & stem and small deadband take little space in the tank, leading to more usable tank volume.

Frequently Asked Questions

What is the accuracy of a Madison single point float switch? What is its repeatability?

Madison stock float switches are accurate within 1/8 inches of the centre of the float travel, with a hysteresis of 1/16 inches. Every switch can switch repeatably within 1/32 inches.

How can I connect my float level switch to a pump or valve while protecting it from the high current that these devices use?

In most applications, a relay is needed for isolating float switches from the device. The float switch is connected in series with a relay input coil that draws current less than 500mAs the switch is closed, the relay coil gets activated and shuts the output contacts. These contacts turn the high current ON or OFF as per the device requirement.

What are the advantages of Madison non-contact level sensors?

  • Madison sensors do not touch the substance being measured. Hence, there is a lower risk of contamination.
  • They are suitable for both liquids and solids.
  • Non-contact sensors require less maintenance.

What factors should be considered while selecting Madison sensors?

Consider factors like the type of substance being measured, the measurement range, environmental conditions, required accuracy and the specific industry requirements.

What are the common applications of Madison float switches?

  • Sump Pumps: To control water levels in sump pits.
  • Septic Systems: Monitoring and controlling sewage levels.
  • Industrial Tanks: Managing liquid levels in industrial processes.

Can Madison switches be used with both high and low-level alarms?

Yes, Madison switches can be configured to trigger alarms for both high and low liquid levels. This dual functionality is valuable for applications where maintaining levels within a specific range is critical.
