Thermocouples are widely used for temperature measurement due to their simplicity and durability. Cold junction compensation is a technique that involves adjusting the output voltage of a thermocouple by adding or subtracting a voltage to simulate a reference junction at 0°C, even if it is not actually at that temperature.
How Cold Junction Compensation Works
A thermocouple functions based on the principle that a voltage is generated at the junction of two different metals. This voltage, or electrical potential, depends on the temperature difference at the junction.
Why is Cold Junction Compensation Important?
Cold compensation ensures accurate temperature readings, maintains measurement consistency and compensates for changes in environment.
