Technology
The principle of operation of a thermocouple is based on the Seebeck' effect, which states that when two dissimilar metals or alloys are joined together at two junctions, a voltage (thermoelectric EMF) is generated that is proportional to the temperature difference between the junctions. One junction called the hot junction, is exposed to the temperature to be measured, while the other junction, known as the cold junction or reference junction, is maintained at a known, constant temperature (often ambient or compensated electronically). The thermocouple generates a small voltage as the electrons move from the hot junction to the cold junction due to the temperature-induced energy difference, creating a potential difference.
This voltage is directly proportional to the temperature difference between the two junctions and can be measured. By referencing standard thermocouple tables or calibration curves specific to the thermocouple types (K, J, T, E, N, R, S, B), the temperature of the hot junction can be accurately determined. Thermocouples are widely used in industrial and scientific applications due to their ability to measure a wide range of temperatures, from cryogenic levels to extremely high temperatures (up to 1700°C, depending on the types), due to their simplicity, durability and compatibility with harsh environments.
Thermocouples are suitable for harsh environments, including high pressure, vibration and corrosive conditions. Different thermocouple types (K, J, T, E, N, R, S, B) cover diverse temperature ranges and environments. They are available in various sizes, making them suitable for small or constrained spaces. Thermocouples work reliably in extreme conditions, including high temperatures, corrosive gases and intense vibrations. High durability and resistance to wear and tear ensures lifetime extension in demanding environments.
