| Abstract: | The effect of individual and matched pairs of resistance thermometers on the error in determining thermal energy by a metering unit is estimated. Criteria for selecting domestic mass-produced matched pairs of resistance thermometers are given and the existing approach to producing matched pairs is analyzed. Metrological requirements, rules, and a program for selecting matched pairs based on a new criterion are formulated. Translated from Izmeritel'naya Tekhnika, No. 11, pp. 32–36, November, 1999. |
