Metrology Upgrading Programme - Temperature Measurement for the Industry: Calibration & Uncertainty Analysis


Course Outline

The course will introduce participants to temperature measurements in the industry, the International Temperature Scale of 1990 (ITS-90) and how temperature fixed points are used to realise ITS-90. The course covers:

  • The principles of measurement traceability, fundamentals of measurement uncertainties and interpretation of calibration reports.
  • The principles of thermocouple for measuring temperatures based on the Seebeck effect and electromotive force (emf) to temperature conversion.
  • The effects of inhomogeneity and sources of errors. 
  • The principles of platinum resistance thermometry and resistance bridges and the use of primary fixed points such as the triple point of water.
An important aspect of the course is the laboratory sessions which are specially designed to provide participants with valuable firsthand experience in the use of state-of-the-art instruments for temperature measurements.
