MEASURING THE TEMPERATURE OF A MOLTEN GLASS BATH

An indirect measurement of the temperature of a molten bath (1) of a viscous material such as glass is made by measuring a parameter such as the motor torque of a rotating mechanical stirrer (3) or the calorific power extracted from its cooling water. This dispenses with a direct measurement of the...

Zusammenfassung:	An indirect measurement of the temperature of a molten bath (1) of a viscous material such as glass is made by measuring a parameter such as the motor torque of a rotating mechanical stirrer (3) or the calorific power extracted from its cooling water. This dispenses with a direct measurement of the temperature by a probe tube fitted with a thermocouple and exposed to difficult operating conditions. On procède à une mesure indirecte de la température d'un bain fondu (1) d'une matière visqueuse comme le verre en mesurant un paramètre tel que le couple moteur d'un agitateur mécanique (3) tournant ou la puissance calorifique extraite de son eau de refroidissement. On se passe ainsi d'une mesure directe de la température par une canne munie d'un thermocouple et soumise à des conditions de fonctionnement difficiles.
