TECHNICAL GUIDE A - TEMPERATURE There are several definitions of temperature, depending on the field to which it refers. For example: Physics: Physical phenomenon occurring as a manifestation of the kinetic energy which indicates the degree of thermal agitation of the molecules in a body or a substance; arbitrary parameter used to measure this phenomenon. Climatology: Energy state of the air leading to varying degrees of heating. Physiology: Heat level of a human or animal body. Temperature is therefore an intensive quantity (quantity used to describe the state of a system whose numeric value...

TECHNICAL GUIDE In particular, for the most widely-encountered temperatures, ITS-90 The emf generated by this temperature difference can be calculated defines : using the following formula: • 14 fixed points between 13.803 K (-259.346 °C) and 1,234.93 K (+961.78 °C) and the interpolation instrument is a standard platinum resistance thermometer; • 3 fixed points above 1,234.93 K (961.78 °C) and the temperature is measured by optical pyrometry, using Planck's radiation law by extrapolation at one of these three fixed points. Today, temperature is the most widely-measured quantity apart from time....

TECHNICAL GUIDE Law of homogeneous metals: This law stipulates that “an electric current cannot be maintained in a circuit composed of a single homogeneous metal, whatever the variations in terms of cross-section, simply by applying heat”. If a junction of two different metals is maintained at temperature T1, while the other is kept at T2, the emf effect produced is independent and not affected by the temperature distribution along the wires T3 and T4. A (+) Law of intermediate temperatures: In industrial installations, it is not easy to keep a thermocouple’s reference junction at a constant...

TECHNICAL GUIDE O = Oxidizing R=Reducing. N = Neutral. V = Vacuum (*) = Sensitive to sulphuric corrosion (**) = Deteriorates quickly in oxidizing environments 4-1 : THE DIFFERENT TYPES OF HOT JUNCTIONS: The part where the hot junction is made is exposed to the temperature to be measured. There are three main types of assembly: • Exposed hot junction • Earthed hot junction • Insulated hot junction Exposed hot junction: This type of junction provides a very quick response time. However, the thermocouple must be used in environments where the conditions are mild (neutral atmosphere, at atmospheric...
