Abstract:

When measuring rapid temperature change as well as measuring high temperatures (>2000 K) commercial pyrometers reach the limits of their performance very quickly. Thus a novel type of high temperature measurement system using a high-speed camera as a two-color pyrometer is introduced. In addition to the high temporal resolution, ranging between 10 μs – 100 μs, the presented system also allows the determination of the radiation temperature distribution at a very high spatial resolution. The principle of operation including various image processing algorithms and filters is explained by means of a concrete example, where the surface temperature decay of a carbon electrode heated by an electric arc is measured.
