It is responsible for high-temperature clarification, homogenization, stirring, and cooling of the glass liquid before sending it to the forming section. Temperature is an important parameter for adjusting the platinum channel process. The stability and reliability of temperature acquisition are particularly important. Since thermocouples age quickly in high-temperature environments, when the collected temperature is distorted, it is necessary to quickly calibrate the thermocouple or switch to a spare thermocouple.

The protective connecting piece is detachably inserted into the through hole. After long-term use, the parts in the temperature measurement system, the temperature measuring element and its connection structure will be more or less damaged and need to be replaced. The fixing plate and the protective connecting piece are set to a detachable connection mode to facilitate the maintenance and replacement of the fixing plate.

Due to the high temperature environment of the thermocouple and the limited installation space on site, maintenance and detection are difficult and time-consuming, and it is difficult to ensure process stability.
