Madison Company

Madison''s liquid level and temperature sensors and switches are ideal in HVAC applications, including air conditioners, boilers, chillers, evaporators and more. Familiar with various agency approvals, our switches and sensors are available in 316 Stainless Steel or Polypropylene, and are an excellent match for any application due to their low-cost, durability, long-life and variety of sizes, styles and technology. Single-point and multi-level float switches are used to control pump up or pump down operations where liquid level accuracy is critical to the performance of the product. Temperature sensors and switches cover a broad range of temperatures, response times and material requirements. Continuous float level switches can be coupled to our full line of digital displays and controllers to meet your application needs. Combined level & temperature products monitor both liquid level and temperature with one switch, saving the cost of using dual monitoring methods.

Madison''s liquid level sensing products can be utilized in many water treatment applications such water treatment plants, reverse osmosis plants and chemical processing plants.

Our non-contact sensors include radar or ultrasonic technology. These sensors are ideal for monitoring liquid levels in large tanks. Hydrostatic pressure sensors are available for use in debris-filled or turbulent tanks. Single-point switches are used for high or low-level indication, pump up or pump down, and valve control. They can be horizontally or vertically mounted, with or without slosh shields, to meet application needs and are ideal for use with relays, controllers, PLCs and intrinsically safe barriers.

Madison''s 316 stainless steel and food-grade plastic liquid level and temperature switches and sensors are ideal for commercial and consumer food equipment applications. Our NSF-approved switches and sensors are suitable for coffee makers, refrigeration systems, fryers, dishwashers, ovens, drink dispensers and more.

Single-point switches are used for high or low-level indication, pump up or pump down, and valve control. Full size or miniature, they can be horizontally or vertically mounted to meet application needs and are ideal for use with relays, controllers, PLCs and intrinsically safe barriers. Combined level & temperature products monitor both liquid level and temperature with one switch, saving the cost of using dual monitoring methods. Multi-level float switches control pump up or pump down operations where liquid level accuracy is critical to the performance of the product. Applications include high- or low-level alarm, liquid measurement and overflow protection.

Madison’s UL- and CSA-approved liquid level sensors and switches are ideal for specialty vehicle applications including off-highway vehicles (tractors, loaders and fire trucks); industrial and commercial trucks (floor cleaners, sprayers, and ice resurfacers) and in green-technology vehicles powered by hybrid fuel cells. Product capabilities include measurement of hydraulic oil, coolant, lubrication, fuel tank or fuel cell level, water tanks and cargo monitoring. Single-point switches are used for high or low-level indication, pump up or pump down, and valve control. They can be horizontally or vertically mounted, with or without slosh shields to meet application needs and can be used with relays, controllers, PLCs and intrinsically safe barriers. Multi-level float switches control pump up or pump down operations where liquid level accuracy is critical to the performance of the product. Applications include high- or low-level alarm, liquid measurement and overflow protection.

Madison''s liquid level and temperature sensors and switches can be utilized for many commercial and military marine applications. ABS-approved stainless steel, brass and Buna-N products are ideal for liquid level monitoring of bilge tanks, fuel tanks, day tanks, grey/black water tanks, water leak detectors & flood protection. Switches with National Stock Numbers can be provided for certain applications. Single-point switches are used for high or low-level indication, pump up or pump down, and valve control. Full size or miniature, they can be horizontally or vertically mounted, with or without slosh shields, to meet application needs and are ideal for use with relays, controllers, PLCs & intrinsically safe barriers. Multi-level float switches control pump up or pump down operations where liquid level accuracy is critical to the performance of the product. Applications include high- or low-level alarm, liquid measurement & overflow protection.
