UNCERTAINTIES IN THE WHOLE RANGE OF CALIBRATION OF A THERMOCOUPLE

Peter Benkó - Rudolf Palenčár

   This contribution describes the procedure of evaluating the calibration of a thermocouple by means of its comparison with the thermocouple standard. In the process of thermocouple calibration by means of comparison, the resulting uncertainty is specified by applying the generalized procedure for evaluating the calibration of measuring devices with continuous scale. The advantage of this method of evaluation is the determination of uncertainties in the whole range of calibration. The conclusion of this paper presents illustrated differences between cases when covariances are taken into account or not.

Keywords: calibration, thermocouple, estimation unknown parameters, uncertainties, covariance.
