Abstract

L'invention concerne une sonde d'oxygène à niveaux qui se fonde sur les variations de la flamme d'une veilleuse située à distance d'une buse lorsque le contenu d'oxygène de l'air comburant diminue. Un thermocouple est positionné de sorte qu'il est situé dans la flamme pendant la combustion à des niveaux d'oxygène acceptables, et dans la zone non exposée à la flamme lorsque le contenu d'oxygène est inférieur à un niveau acceptable. La grande différence de tension entre un niveau élevé et un faible niveau d'oxygène améliore la fiabilité de la sonde.
