Temperature is one of the most widely measured physical quantities and plays a crucial role in production processes and quality assurance in the glass industry.
Industrial Pyrometers (radiation thermometers) are working in temperature measuring ranges from 50 to 2500°C and are used to regulate the process.
In addition, material limits and alarm values can be monitored.
Most applications for temperature measurement are in the glass-melting furnace, in the work tub, in the feeder area or in the glass drop measurement.
In addition, in the manufacture of container glass, pyrometers monitor the temperature of the molten glass in the vault and in the glass tank and also the temperature of the mold itself.
Often devices must be specially adapted to the particular application and the operating conditions to achieve physically meaningful and optimal measurement results.
An example is the measurement of ultra-thin glasses or so called low-emissivity glasses.
