Madison Company is now offering its full line of liquid level switches in PTFE (polytetrafluoroethylene) for high-purity applications such as medical/pharmaceutical products and food or beverage dispensers. PTFE switches are also suitable for electronic component manufacturing, sterilization systems and applications where strict biosafety standards must be met.

PTFE is a chemically inert material that allows the switch to withstand aggressive solvents such as alcohols, esthers and ketones as well as other corrosive acids and bases, oils, steam and most chemicals. PTFE has a very smooth surface area that hinders the formation of bacteria, rejects material build up and does not absorb liquids. It is considered to be a better choice than FDA approved polypropylene in certain chemical, medical, food and beverage applications. Switches manufactured of PTFE can be used effectively in sterilizers and other biomedical equipment because they can withstand higher operating temperatures (up to 260°C) and caustic agents in the environment better than polypropylene switches.

The float can be offered in standard PTFE or with an advanced, chemically modified PTFE for superior thermal and mechanical characteristics. The modified PTFE allows some designs to be offered without the spring assist found in many heavier float designs. With Madison's highly reliable reed switch technology and PTFE wetted materials, these liquid level switches offer dependability over a long service life. PTFE switches are available in standard and engineered designs.
