MEASURING THE TEMPERATURE OF A MOLTEN GLASS BATH

摘要

One proceeds with indirect measurement of the temperature of a molten bath (1) of a viscous material such as glass by measuring a parameter such as the motor torque of a rotating mechanical stirrer (3) or the heating power extracted from its coolant water. One thereby dispenses with direct measurement of the temperature by a rod provided with a thermocouple and subject to difficult operating conditions.
