INFRARED TEMPERATURE MEASUREMENT OF THERMALLY TEMPERED LOW EMISSIVITY GLASS
We propose a solution that uses a 5µm line scanner measuring the low emissivity surface through the narrow gap between the furnace and air blowers, aligned with a 5µm spot thermometer taking measurements of the underside of the glass. The spot thermometer signal is used to compensate for the low emissivity of the upper surface of the glass. A true temperature thermal map of the entire product surface with sub-spot resolution is created in software from successive scan data, which can be used to adjust furnace control parameters and produce visually perfect glass.
