In these situations measurement at depth is desired to overcome temperature gradients and produce a "bulk" temperature. 68th Conference on Glass Problems · 41 Applications and Challenges for Infrared Temperature Measurement in Glass Manufacturing LOW EM1SS1V1TY GLASS Low-emissivity (low-e) glass refers to glass that has a special coating applied to it so as to control heat transfer through the window. Typical coatings are microscopically thin layers of metal or metal oxides, almost invisible to the naked eye.
In order to equalize the data displayed in Figure 14, the ratios of tons changed to time required for gob temperature stabilization were calculated. Figure 15 displays the averages of the calculated ratios defined as the gob temperature recovery rate for the different control methods. 36 · 68th Conference on Glass Problems Gob Temperature Control Model Based Control of Gob Temperature Model Based Control of Mass Flow Temperature PID Control Figure 15: Gob temperature recovery rate after a job change CONCLUSION The BASF Exactus advanced gob temperature sensor is capable of providing an accurate and repeatable temperature measurement of each sheared gob.
Tempered glass is used in areas where such large shards could cause injury in the event that the glass panes were to break. Application examples include glass doors and windows below a certain height. As is recently the case with low-e glass, the use of tempered glass in building is frequently mandated by building codes. As one can imagine, since exposing it to high temperature and then rapidly returning it to a lower temperature alter the glass properties, measurement and control of temperature is a key parameter of the glass tempering process.
