Sensors For Medical, Pharma and Healthcare Applications

Madison Company’s rugged liquid level sensors have been trusted to reliably detect accurate fluid levels in medical applications for 60 years.

Madison sensors are used wherever critical fluid levels must be monitored, including fluid waste containers, sterilization tanks, ventilators, high flow respirators, parts washers and chemical dosing equipment.

Fluid sensing applications in the medical and pharmaceutical industries often involve caustic chemicals and special challenges. Madison sensors and switches carry many 3rd-party certifications, including UL, UL Haz Loc (explosion-proof), CSA, and NSF, ensuring suitability in safety-critical systems. We offer a variety of fluid level sensors for use with semi-solid, corrosive, and other difficult liquids. Madison Company is an ISO 9001:2015 certified manufacturer.

  • Wide variety of chemically resistant materials available, including 316 Stainless Steel, polypropylene and Kynar
  • Technology options such as point level and continuous level reed switch-based sensors, optical, conductivity, temperature, pressure, ultrasonic and radar level sensors
  • Custom engineered liquid level solutions for specialized applications

Custom Miniature PVC Liquid Level Switches

The Madison M6002- & M6005- PVC family of sensors are ideal for medical bottles or corrosive chemical applications. These cost effective PVC plastic materials provide durability and reliability when sensing critical levels in single point or multi-point levels in reagent bottles. Where level detection is needed in bottles with siphon or return tubes, the M6005– series can be designed with dual tube functionality within a single tank fitting. Slosh shields, fill tube/siphons and other features can also be incorporated for OEM quantity projects.
