Utica-Dunkirk 240008227 1/4" Flue Sensor 12K Ohms NTC

The Utica-Dunkirk 240008227 1/4" Flue Sensor 12K Ohms NTC monitors flue temperature by detecting heat changes through its Negative Temperature Coefficient sensing element, which decreases in resistance as temperature rises. These resistance variations are interpreted by the control system to determine current exhaust conditions and adjust equipment operation accordingly. It is installed in HVAC systems the sensor provides data from the flue area for combustion monitoring and control response. Accurate temperature readings maintain proper communication with the controls, ensure a regulated heating cycles, and keep the equipment operating according to preset settings.
