Adjustable Dead Band Weatherproof Pressure Switch

The SOR V1 adjustable dead band weatherproof pressure switch is a low-cost alternative to its explosion-proof counterpart.

It is best used in non-hazardous locations where a wide, adjustable dead band between set points is required.

The switch incorporates two industry-proven static O-ring pressure sensing elements.

Media pressure on the areas of the pistons counteracts the forces of the independently adjustable piston springs and moves the piston shafts to operate the lever assembly, which in turn, actuates and de-actuates the electrical switching element.
