Measuring device for a flame

Abstract

The present invention describes a measuring device for a flame, in particular for use in a control device for a burner (13) arranged with a in the flame region (14) of the burner ionization electrode (15) to which an alternating voltage is switched, whereby the depending ionization a DC component superimposed. DOLLAR A The flame resistance affects the AC voltage and the DC voltage at the capacitor block unequal. The AC voltage is above the first means (5, 6) from the DC voltage component can be separated and the separated AC voltage with the separated DC voltage component via second means (9, 10) to produce comparable and a pulse width modulated signal.
