Single Diaphragm – Weatherproof Differential Pressure Switch with Terminal Block Connections

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 over-range, proof, shock pressure, or cycle rates are expected. They are one of the best-performing differential tops in repeatability and are 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.
