Madison Liquid Level Switch

The Madison Liquid Level Switch is a selectable-function sensor with a 1/2-13 UNC tank connection made from 316 stainless steel. It is built for industrial liquid monitoring where corrosion resistance and reliable level detection are required.

Side mount with selectable switch function

Side mounting simplifies tank installation and the switch function is selectable for normally open or normally closed operation. The 1/2 inch conduit size and SPST contact form keep wiring straightforward, though installers must verify the 0.28 A and 240 V limits match the control circuit.

Suits corrosive liquid tanks up to 100 psi

This switch suits tanks holding corrosive liquids at pressures up to 100 psi and temperatures up to 392 degrees Fahrenheit. Buyers needing a different thread size, higher current rating or a non-stainless body should look at other level sensors.
