Abstract

a. Procédé et dispositif pour surveiller si une sonde à oxygène est prête à fonctionner. b. Procédé caractérisé en ce que pour détecter la résistance interne de la sonde qui indique si la sonde est prête à fonctionner, on lui oppose une tension de référence, constante, et la tension résultante de l'action du comportement de la sonde est détectée par deux comparateurs ayant des tensions de seuil qui se trouvent au-dessus et en dessous de la tension de référence, et en ce que les signaux de sortie logiques, compatibles, fournis par les comparateurs sont exploités par un circuit de combinaison, aval, commandé dans le temps, et l'installation de préparation du mélange est commutée du mode réglage au mode de commande ou inversement
