Single Diaphragm – Weatherproof Differential Pressure Switch

101/121 NN model single diaphragm differential pressure switches are built rugged 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.              

These, field-mounted instruments feature a flexible modular design that provides cost-effective sensing solutions for air, oil, water, and non-corrosive process fluid applications. The two-piece piston design allows for complete differential pressure reversal without damage.

• Low Cost
• Ranges from 3 to 500 psid
• Set point adjustment with calibrated scale
