Amcor Ltd and Owens-Illinois Inc. are the two major manufactures of glass bottles in Australia and have a long association with Pyrosales. Glass manufacturing requires high-temperature sensors.Furnaces used to make glass work at up to 1575°C, requiring platinum-based thermocouples. Thermocouples are used in measuring the furnace atmosphere temperature, the furnace glass temperature, and the temperature of the glass as it flows through the fore hearth, where it is conditioned to efficiently make glass bottles.
The crown thermocouples typically measure the highest temperature, and depending on the type of glass and temperatures required, will use type B thermocouples with recrystallised alumina sheaths.
Pyrosales has extensive experience supplying thermocouples to the glass industry and can custom-design and manufacture the temperature sensors required.
