Tips: What is cold junction compensation, and why is it important for Pt100 sensors?

Cold junction compensation is a technique used to ensure accurate temperature readings despite temperature variations at the sensor's connection point. In Pt100 sensors, which operate based on the resistance of platinum that varies with temperature, it’s crucial to account for the temperature at the "cold end" (or connection point) to maintain measurement accuracy. Cold junction compensation allows the sensor to correct any deviation caused by these external temperatures, ensuring that the reported temperature reflects only the actual measurement area. This is particularly important in industrial settings with fluctuating ambient temperatures.
