PreSet Series

Scaled Adjustable Current Switches
Higher Reliability, Faster Installation, Superior Accuracy | Sense the Difference

Scaled calibration for proof of flow set-point
Split and solid core models to 150A
N.O. 30VAC/DC or 120VAC output
Optional command relay
  • Preset™ scaled calibration enables set-point adjustment for proof of flow by simply matching dial to motor full load amps (FLA) nameplate
  • Safer--eliminates calibration in energized enclosures, reduces arc flash hazard
  • Proven to save up to 1/2 hour per need to return to calibrate live
  • Prevents call-backs, no multi-turn potentiometers and guesswork to find set-point
  • Super low turn-on for compatability with smaller motors
  • Solid-state-more reliable than mechanical pressure switches for proof of flow
  • Quality backed by 7 year limited warranty



PreSetâ„¢ allows for matching sensor set-point to the motor nameplate, eliminating the need to calibrate in energized enclosures and reducing installation time. Sensor will detect motor undercurrent conditions such as belt loss, coupling shear, and mechanical failure on fans and pumps.  


  • Detecting belt loss, coupling shear, and mechanical failure on fans and pumps
  • Monitoring status of industrial processes
  • Monitoring status of critical motors
