Q. The temperature of cold junction of thermocouple is $0{^\circ}C.$ If the neutral temperature is $270{^\circ}C,$ then the inversion temperature is
A) $540{^\circ}C$
B) $520{^\circ}C$
C) $640{^\circ}C$
D) $58{^\circ}C$
Explanation
(a) Neutral temperature, $T_{n} = \frac{T_{i} + \ T_{c}}{2}$
or $T_{i} = 2T_{n} - \ T_{c} = 540℃.$
