| Zusammenfassung | The thermodynamic temperature of the freezing point of copper was measured by noise thermometric methods. A conventional approach was used which combines the noise voltage of the measuring resistor with that of a reference resistor maintained at a known temperature. Besides this comparison method the thermometer is characterized by a two-channel arrangement to eliminate parasitic noise of electronic components by cross correlation. The thermo-dynamic temperature measured at the freezing point of copper amounts to a value of 1084.54 °C ± 0.12 K (k = 2). This corresponds to the value of the ITS-90 temperature of this fixed point of 1084.62 °C within its thermodynamic uncertainty of 0.12 K (k = 2). |
