Noise Thermometry - Page 4
The process is shown here. We measured some property of
the sensor in the thermometer, perhaps thermal EMF or resistance.
We then relate that to a temperature scale such as the Kelvin
scale by a process of calibration. This might be a calibration
of the particular thermometer or just a generic calibration
using the know typical characteristics of the thermometer
type to relate the measurement to the temperature scale.
It is then the latest agreed international temperature scale
ITS90 that relates this scale to the best known value of
the true thermodynamic temperature of the sensor.
