Abstract (en)
[origin: WO2019122976A1] A control device (1) for control and detection of the flame of a burner (200), comprising an ionisation electrode (2) arranged, in use, at a region in which a flame of the burner (200) is present, and an electric circuit (3) for generating a triangular voltage signal (Vtr) having a triangle wave form and connected to the ionisation electrode (2) in such a way that on varying the ionisation current (Ion) the average value of the triangular voltage signal (Vtr) also varies. Said device (1) comprises at least an output circuit (1 1) connected to the circuit (3) for generating the triangular voltage signal (Vtr) and comprising an electronic group (12) for generating a duty-cycle as a function of the average value of the triangular voltage signal (Vtr).
