| Zusammenfassung | The SRD1000 device supports 9 reference temperatures on the PLTS-2000 using superconductive to normal transitions of various metals. The evaluation of prototypes by several European metrological institutes showed that the SRD1000 concept is convenient and reliable for transferring the scale. Currently a pilot production series is being developed with improved quality for the superconductive transitions of W, Be, Zn and Cd compared to the prototypes. To achieve this we apply better techniques for preparing the metals and add EMI filters to the electrical leads of the devices. We report on technological improvements and present results of calibrations of the devices on the PLTS-2000. For interpolation between the reference points the sensor will be provided with an internal magnetic thermometer. |
