Web1 de jul. de 2024 · In a standard structure, a thermocouple is made up of two conductors/metals that are joined together to form a measuring junction. Use of two dissimilar conductors having different Seebeck coefficients ( S= Δ V/ Δ T ; Δ V is the voltage produced along a conductor due to the temperature gradient, Δ T ) is essential to build a … Web19 de jul. de 2012 · One junction is designated the hot junction. The other junction is designated as the cold or reference junction. The current developed in the loop is proportional to the difference in temperature between the hot and cold junctions. Thermocouples measure differences in temperature, not absolute temperature.
