In a thermocouple, the temperature that does not depend on the temperature of the cold junction is called
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand thermocouples. A thermocouple consists of two different metals joined at one end, which produces a voltage as a result of a temperature difference between the junctions.
Step 2: The cold junction is at a known temperature, while the hot junction's temperature is what the thermocouple measures.
Step 3: The term 'neutral temperature' refers to the temperature at which the thermoelectric properties of the two metals balance out, resulting in no voltage change regardless of the cold junction's temperature.
Step 4: In contrast, the 'temperature of inversion' does relate to changes in the cold junction's temperature influencing the output voltage, so it is not independent.
Conclusion: Therefore, the correct answer is Option A, Neutral temperature.
