Question

The neutral temperature of a thermocouple is $300^\circ C.$ What is the inversion temperature, if the temperature of cold junction is $10^\circ C?$

A

$590^\circ C$

B

$610^\circ C$

C

$310^\circ C$

D

$290^\circ C$

Answer

$590^\circ C$

Explanation

Solution

For a thermocouple $T_i=2T_n-T_0$ $\hspace15mm T_i=2 \times 300-10$ $\hspace15mm T_i=600-10=590^\circ C$
