Question

In a given thermocouple, the temperature of cold junction is $0^{0}C$, while the neutral temperature is ${270}^{0}C$. The temperature of inversion is

• A. ${270}^{0}C$
• B. ${540}^{0}C$
• C. ${520}^{0}C$
• D. ${550}^{0}C$

Answer 1

The correct option is B ${540}^{0}C$

$T_n=\frac{T_o+T_i}{2}$
Given,
$T_n={270}^{0}C$
$T_o=0^{0}C$
$T_i=2\times 270-0={540}^{0}C$
