Thermocouple Measurements with ΔΣ ADCs
... As discussed earlier, the thermocouple generates a voltage that is related to the temperature difference between the two ends of the wires TX and TREF (see Figure 2). If the temperature at TREF is known, then the tempature at TX can be computed. The process of accounting for TREF is called cold junc ...
