Glass gob temperature measurement

Glass gob temperature measurement is only possible using non-contact thermometers. The pyrometers needed for this application have to be fast due to the high cycle frequency and must be capable of measuring the temperature inside the gob. This is needed because the surface temperature of the glass is easily influenced by ambient conditions. The measuring depth is adjusted to suit the type of glass or size of gob by selecting different spectral ranges. 

 

Process		Conditions		Recommended pyrometers
Glass gob temperature measurement		Only possible with fast non-contact thermometers. The optimal choice of the pyrometer depends e.g. on the type of glass and the size of the gob. Usually the maximum measured temperature value is stored (peak picking) for subsequent processing. Portable pyrometers and fixed systems are applicable.		e.g.  IS 5-LO/GL IS 50-LO/GL ISR 12-LO  IPE 140/39 IGA 12 ISQ 5 IS 8 plus
