Abstract
L'invention concerne une installation de détection de flammes. Cette installation comprend deux filtres fasse-bande, l'un pour la radiation de résonance de l'anhydride carbonique, l'autre pour une radiation de longueur d'onde voisine. Un dispositif photo-électrique permet de connecter en signaux électriques, les radiations sortant des filtres. Un circuit de retenue comprenant deux commutateurs et deux condensateurs associés respectivement avec chaque filtre, enregistrent les signaux issus du dispositif photoélectrique. Des moyens permettent de calculer le quotient des signaux enregistrés dans chaque condensateur, tandis que d'autres moyens permettent de comparer ce quotient avec une valeur de référence et commandent un dispositif d'amortissement à chaque fois que la comparaison indique le dépassement d'une valeur de référence. Application à la détection de flammes, en présence de rayons solaires d'intensité élevée.
