The extremely high temperatures and challenging atmospheric conditions involved in glass melting and fining processes require the application of special thermocouple technology. These thermocouples need to be capable of accurate measurement whilst demonstrating the minimum in temperature drift over time.
This long term stability is a key factor in a glass manufacturer’s ability to control and operate processes to the limits of acceptable glass quality whilst achieving the best in energy efficiency.
Furthermore, if thermocouple technology is applied to measure and protect critical areas of the furnace, such as the crown against overheating, it is imperative that these sensors are both reliable and robust over long periods of time.
