Department 7.4
Staff Tasks
- Primary thermometry (determination of thermodynamic temperatures) in the temperature range from about 1 K to above 2000 °C by means of noise thermometry and gas thermometry
- New determination of Boltzmann's constant
- Realisation of the Provisional Low Temperature Scale PLTS-2000 from 1 mK to 1 K by Helium-3 melting-pressure thermometry and reference points
- Realisation of the International Temperature Scale ITS-90 from 0.65 K to 962 °C by means of vapour-pressure thermometry, gas thermometry, temperature fixed points and platinum resistance thermometers
- Dissemination of temperature scales from 1 mK to 273 K by calibration of thermometers and reference materials
- Calibration of standard platinum resistance thermometers from 14 K to 962 °C
- Calibration of other contact thermometers in the temperature range from −80 °C to 1600 °C
- Development of new techniques for approximating the ITS-90 in the temperature range from 0 °C to 2200 °C (special fixed points and thermocouples)
- Development of new calibration methods and transfer standards
- Investigation of superconductive reference points, temperature sensors and thermal measurement errors
- Type testing and pattern approval for initial verification of contact thermometers
- Specific tasks for the German calibration service DKD, measurand temperature
- Collaboration at thermometry organisations and legal bodies (CCT, CODATA, EURAMET, Coomet, OIML, IEC, DIN, VDI/VDE)
