Question: The neutral temperature of a thermocouple is $ 350^{o}C $ when the cold junction is at $ 0^{o}C. $ When the cold junction is immersed in a bath of $ 30^{o}C, $ the inversion temperature is

[Kerala (Med.) 2002]

Options:

A) $ 700^{o}C $

B) $ 600^{o}C $

C) $ 350^{o}C $

D) $ 670^{o}C $

Show Answer

Answer:

Correct Answer: D

Solution:

$ t _{i}=2t _{n}-t _{c} $

Therefore $ t _{i}=2\times 350-30=670^{o}C $
