ABSTRACT:
A detection device comprising two spark-gap electrodes connected to a voltage pulse source having an amplitude greater than the striking voltage of the spark-gap, so that each pulse produces a spark between said electrodes. Such a detection device is characterized in that it comprises, connected to at least one of the electrodes, a detection circuit able to supply at its output a signal whose amplitude is representative of a definite condition of the atmosphere present between said electrodes, particularly of the presence or of the absence, between the electrodes, of an ionized gas such as a flame.
Main uses: devices for the generation of sparks for igniting a fuel.
