Question
Consider the following statement regarding a thermocouple:
  1. The neutral temperature does not depend on the temperature of the cold junction.
  2. The inversion temperature does not depend on the temperature of the cold juhction.
  1. Both A and B are correct.
  2. A is correct but a is wrong.
  3. B is correct but A is wrong.
  4. Both A and B are 1trong.
✓

Answer

  1. A is correct but a is wrong.

Explanation:

At cold function :

Qn - Qc = Qi - Qn

where Qn Þ neutral temperture

Qi Þ inversion temperature

Qc Þ thermo-couple temperature.

Þ The neutral temperature does not depend on the temperature of the cold function.

Þ The inversion temperature does depend on the temperature of the cold function.
