Temperature Measurements In The Glass Melt

The problem of measuring temperature distribution in the volume of materials which are partially transparent for heat radiation is considered. A valuation of the accuracy of thermocouple measurements is carried out and the possibility of using the specifics of the temperature field by outgoing radiation is also reviewed. A simple method is suggested for a subermsible optical probe for measuring temperature in a volume of melted glass. A diagram of the measurement is presented, the methodology and experimental results are discussed. They show that in a lower area of the melt their are large temperature gradients. This is caused by the specifics of radiation conductive heat transfer.
