TEMPERATURE MEASUREMENT BY CALIBRATED SPRT IN ACCORDANCE WITH ITS-90

Rudolf Palencár - Stanislav Ďuriš - Rudolf Brdečka

   Procedure of the evaluation of temperature measured by a standard platinum resistance thermometer (SPRT) is presented in this contribution. It is based on the estimation of the parameters of the deviation function and their uncertainties and covariances. Application of the proposed procedure is illustrated on an example of temperature measurement by the SPRT calibrated in the temperature range from 0°C to 660°C.

Keywords: calibration model, temperature measurement, uncertainty, covariance, temperature scale
