| Zusammenfassung | At Physikalisch-Technische Bundesanstalt (PTB) a caesium heatpipe blackbody radiator and a sodium heatpipe blackbody radiator directly traceable to the International Temperature Scale of 1990 (ITS-90) were developed. They are used as reference calibration sources for infrared radiation thermometers. The temperatures of the blackbody radiators are defined by standard platinum resistance thermometers sensing the cavity temperature in terms of the ITS-90. The validity of the approach is demonstrated by calibration of a high resolution infrared radiation thermometer. The calibration results of the radiation thermometer above 550 °C were compared to calibrations against the double-heatpipe large area blackbody LABB. The results of the investigation are summarized by an estimation of the overall uncertainty of the calibration facility. |
