Equalising line
Equalising cables are used in the field of temperature measurement with a thermocouple. (Thermocouples e.g.: Fe/CuNi iron constants (blue); NiCr/Ni nickel-chromium-nickel (green); PtRh/Pt platinum-rhodium-platinum (white). A thermocouple consists of two conductors made of different materials, between which an electrical voltage is generated depending on the temperature. An equalising cable now transmits this voltage from the thermocouple to a reference junction. There, the temperature at the measuring point can be assigned based on the voltage level.
