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 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.

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