Уменьшение неопределенности температурной шкалы посредством учета корреляции между сопротивлениями при калибровке и измерениях
Abstract
The possibility of reduction of temperature scale realization uncertainty by means of taking into account the correlation beetween resistors during resistance thermometers calibration and at temperature measurement is considered. It is shown that if all resistors during calibration and measurement have the same error, it does not affect the uncertainty of ITS-90 temperature scale. The equations for temperature scale uncertainty calibration with taking into account the correlation beetween the resistors, obtained as a result of modeling, are presented.
