Description
Utica-Dunkirk 240008225 OTDR Sensor 12K NTC 3% is used to measure temperature change through resistance variation. It provides accurate thermal information to the control system for monitoring operating conditions within heating equipment. In HVAC systems, it is installed on or near the heat exchanger, or water circuit where it track temperature levels during operation. It supplies data to the control board to support ignition control, modulation and safety operation, helping maintain stable heating performance, prevent overheating, and ensure consistent system regulation during burner operation.
