CA 2073688

The apparatus is comprised of two sensors of the thermal type (11a, 11b) made of materials resisting without any alteration to a temperature of 650 DEG C. Probes (15a, 15b) are controlled by a microprocessor (16) to come periodically and momentarily in contact with said sensors in order to calculate (through microprocessor (16)) the thermal time constant of said sensors presenting a deposition layer of environmental pollutants. The microprocessor (16) compares the value of said time constant with an order value that commands the closure of a shunt switch (17) of a resistance (18) which, when short-circuited, determines a reinforced heating of the sensors to bring them to a temperature of incineration of organic materials originating from the pollution of the ambient medium and deposited on said sensors. Thus, the sensors are maintained in the cleanliness conditions of their surface, thereby providing for the accuracy of information supplied by said sensors outside cleaning periods.

2073688 9208956 PCTABS00130 L'appareil comprend deux capteurs du type thermique (11a, 11b) en matériaux résistant sans altération à une température de 650 ·C. Des sondes (15a, 15b) sont commandées par un microprocesseur (16), pour venir périodiquement et momentanément en contact avec ces capteurs, afin de calculer (par le microprocesseur (16)) la constante de temps thermique de ces capteurs présentant une couche de dépôt de produits de pollution de l'ambiance. Le microprocesseur (16) compare la valeur de cette constante de temps avec une valeur de consigne et commande la fermeture d'un interrupteur de shuntage (17) d'une résistance (18) qui, lorsqu'elle est court-circuitée, détermine un chauffage renforcé de ces capteurs les portant à une température d'incinération des matières organiques provenant de la pollution du milieu ambiant et déposées sur ces capteurs. Ainsi, les capteurs sont maintenus dans les conditions de propreté de leur surface assurant l'exactitude des informations fournies par ces capteurs en dehors des périodes de nettoyage.
