Abstract (en)
[origin: EP1211460A2] The burner monitoring circuit has a changeover voltage (Uion) connected ionization electrode (Iioni) mounted adjacent to the burner flame. It has an evaluation monitor connected to a compensating voltage source (Ub) with a ionization electrode current flow controlled transistor (T152). The negative pole of the compensating source (Ub) is connected to the burner mass. The positive pole is connected to a deep pass filter (C154) to the ionisation electrode.
