| Zusammenfassung | This paper is focused on self-validation and in-situ validation methods of thermometry between 1000 ºC and about 1800 ºC. An operative approach of reliable self-validating contact thermometry sensors and the implementation of traceable measurement methods for the measurement of temperatures up to about 1800 °C in oxidizing atmospheres will be presented. Miniature fixed points filled with high purity Au (1064.18 °C), Pd (1553.4 °C) and Pt (1769 °C) have been constructed and assembled with type B thermocouples to be used as traceable references in oxidizing atmospheres. The use of electrical noise thermometry as an additional method for realization of the self-validation principle was applied. Combined thermocouple-noise temperature sensors have been constructed to allow long-term determination of thermocouple drift. Electrical noise thermometry is a primary method to measure temperatures without drift effects even over long periods of time. An uncertainty of noise temperatures measured of 0.1% has been achieved which is sufficient to determine and correct for thermocouple drifts in industrial use. |
