WebThe thermocouple has a unique additional correction called cold junction compensation. It is unique among temperature sensors, and it is often misunderstood. The reason for the compensation is that the thermocouple only reports the relative temperature difference between the sensing end and the terminals where it is connected. WebMar 14, 2024 · Cold junction compensation compensates for the missing thermoelectric voltage due to the fact that the thermocouple cold end at the instrument is not at (0°C /32°F). This then allows electronics to use …
