VGA infrared camera for the glass industry
With its 7.9 µm filter, the thermal imager optris PI 640 G7 is perfectly suited for the measurement of glass and, due to the VGA resolution, offers an even wider range of possible fields of application. “The software optris PI Connect enables the use as a line scan camera, which is essential for the temperature control of glass ribbons and glass panes” declared Torsten Czech, Head of Product Management at Optris.
Temperature measurement under difficult conditions
Temperature monitoring is crucial in the glass industry and it is an integral part of almost all stages of the production process. In confined and hot surroundings, temperature can sometimes only be determined by room sensors. The compact infrared thermometers and cameras of Optris enable the operation even in confined spaces with high temperatures. The thermal camera monitors the temperature distribution in cooling processes of flat glass production as well as in the production of container glass.
The material glass requires special sensors
For the accurate measurement of temperatures, emissivity is a key factor. Glass usually exhibits an emissivity of 0.85 µm in the longwave range. In processes with higher temperatures, it is measured with 5.0 µm or 7.9 µm because in those spectral ranges the emissivity is ≥0.95. The main advantage of 7.9 µm is the lower angel dependency of the emissivity.
