Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question No. 2020-08-02: Discussion question: 194. What are the three elements of a temperature scale?
Answer: 1) The equilibrium temperatures of certain pure substances were selected as reference points for the temperature scale. 2) Standard instruments for different temperature ranges were specified. 3) Interpolation formulas relating the readings of the standard instruments to the International Temperature Scale were established.
Thermometric substances and their thermometric properties, calibration points, and scaling methods.
Temperature-measuring substances and their temperature-measuring properties, calibration points, and scaling methods
Thermometric substances and their thermometric properties, calibration points, and scaling methods.
The equilibrium temperatures of some pure substances were selected as the reference points for the temperature scale； Specifies the reference instruments for different temperature ranges ； An interpolation formula relating the indication of the reference instrument to the International Temperature Scale was established.
Thermometric substances and their thermometric properties, reference points, and calibration methods.
The three elements are the temperature-measuring substance and its temperature-measuring properties, the reference point, and the calibration method.
