The temperature of cold junction of thermocouple is

0\,^\circ C

. If the neutral temperature is

270\,^\circ C

, then the inversion temperature is

View answer and explanation

Correct option: A

540\,^\circ C

Option A (

540\,^\circ C

) is correct because the inversion temperature is twice the neutral temperature when the cold junction is at 0°C.
