Flame Detector Explosion proof with Line of Sight model NFDL-2545-N2Ex

This model is a Line of sight flame detector that is installed directly on the furnace. The light of flame by the optical lens is focused on the sensor. The sensor converts the light into electrical signals. The flame signal is analyzed by the central processor and monitored in the output.
