      Supervision of light radiation of oil flames in the visible range of the light spectrum. The light-sensitive element is a photo resistor whose electrical dark resistance lies in the M range. As the intensity of light increases, the electrical resistance drops to the k range and is evaluated by the burner control for generating the flame signal. In contrast to the photocell ot the RAR, glowing firebrick in the combustion chamber can be detected.
