Preventive maintenance is limited to an annual visual inspection and can be accomplished by a technician with basic electrical skills (wiring).

      • No additional set-up or calibration required
      • Set points can be linked to provide “pump-logic”
      • Pressure from vacuum to 2000 psi, temperature from -40°F to 250°F
      • Relay and current shift (8/16 mA) output available
      • 316SS, Alloy 20, and Hastelloy-C sensors
