101NN 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 overrange, 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.
