What We Offer…

Standard single level – Vertical – Stainless steel float switch

These level switches are ideal for high temperature and pressure applications. The rugged construction allows for the sensors to be used for reliable switching in a wide variety of chemicals, oils, and water even in harsh environments. Their operating temperature is -40F to 300F, with a range of maximum pressure, from 150 – 750 PSI

Standard single level – Vertical – Polypropylene float switch

Polypropylene allows for a low cost switch while still offering a high volume use with reliability and compact size. They have broad compatibility with various chemicals, oils, and water, with a max pressure of 150 PSI and operating temperature of -40F to 212F and -15F to 175F depending on the model.

Standard single level – Vertical – PVC & PTFE float switch

The PVC provides similar advantages as polypropylene but differs with a max PSI of 50 and an operating temperature of 140F in water and -40F to 230F in oil.

PTFE is ideal for ultra pure, highly corrosive applications. The non-stick nature of of PTFE resists the buildup of foreign materials and sticky media. Our PTFE float sensors have a max pressure of 25 PSI at 150F but an operating temperature range of -40F to 375F.
