Common HVAC&R Applications
  • Gas fired warm air furnaces - improve fan flow by sensing draft down from blower; switch actuation allows ignition start up or shuts system down upon insufficient draft
  • Electronic air cleaners and humidifiers can employ sensing switches to prove airflow; switch actuation starts unit with sufficient airflow or draft
  • Strip heaters employ airflow sensing switches to prove positive pressure/airflow in duct and air movement across heat source; shuts off heat source with insufficient airflow
  • Exhaust fans and draft hoods employ sensing switches to sense draft down from exhaust fan; switch actuation signals condition upon fan failure or insufficient draft
  • Refrigeration and cooling coils are maintained by sensing differential pressure/airflow drop across coils; switch actuation signals condition when they ice, or actuates the defrost cycle
