SOR 101/121 weatherproof differential pressure switches are suited for low-to-high differential pressure, fluid power or process applications where high and varying static pressures, high overrange, proof, shock pressure or cycle rates are expected. They are one of the best performing differential tops in repeatability and designed for use in non-corrosive process media. Optional components may be added for corrosive environments.

The 101RN and 121RN are low-cost, rugged, field-mounted instruments incorporating a flexible modular design that provides cost effective sensing solutions. The two-piece piston design allows for complete differential pressure reversal without damage.
