Device for checking the combustion quality.

摘要

The invention discloses a device for the control of the quality of the light of the flame in a combustion system. It comprises an electronic circuit to which a photo resistance is connected. At the terminals (11, 12) of said photo resistance a tension signal is read which, after being suitably treated, feeds an amplifier (7) controlling the lighting up of some leds (8) arranged in a scale, so that the lighting up of the maximum number of leds corresponds with the maximum tension read at the terminals of the photo resistance and vice-versa. <IMAGE>
