Abstract

LA TEMPERATURE DE LA PHASE LIQUIDE OU DE LA PHASE SOLIDE EST RELEVEE SUR LA COUCHE LIMITE METAL 8RECIPIENT 7 AU MOYEN D'UN CONDUCTEUR OPTIQUE 9 DONT LA FACE DE FRONT 9A EST SUR LA FACE INTERNE DU RECIPIENT 7. LE SIGNAL OBTENU EST TRANSMIS PAR UN AUTRE CONDUCTEUR OPTIQUE SOUPLE 10 A UN PYROMETRE A RAYONNEMENT INFRAROUGE 11, PUIS A UN CONVERTISSEUR DE MESURE 1 QUI COMPARE LA COURBE DE LA TEMPERATURE EN FONCTION DU TEMPS AINSI OBTENUE A UNE COURBE DE REFROIDISSEMENT NEWTONIENNE AJUSTEE POUR RECOUVRIR LA SECTION CORRESPONDANTE DE LA COURBE MESUREE.
