Find the neutral temperature and inversion temperature of copper-iron thermocouple if the reference junction is kept at 0°C. Use the data in table (33.1).

Question

Philoid · Accepted Answer

Neutral temperature is given by -

Using table data –

Similarly

Thus, the neutral temperature becomes,

Since, temperatures is in Celsius, the inversion temperature is double the neutral temperature, i.e. 659°C.
