Vedclass · Answer

(C) The neutral temperature $(t_n)$ is a property of the thermocouple materials and is independent of the cold junction temperature $(t_c)$. Therefore,the neutral temperature remains $270^{\circ}C$.The temperature of inversion $(t_i)$ is related to the neutral temperature and cold junction temperature by the formula: $t_i = 2t_n - t_c$.Given $t_n = 270^{\circ}C$ and the new cold junction temperature $t_c = 40^{\circ}C$:$t_i = 2 	imes 270^{\circ}C - 40^{\circ}C$$t_i = 540^{\circ}C - 40^{\circ}C = 500^{\circ}C$.Thus,the neutral temperature is $270^{\circ}C$ and the temperature of inversion is $500^{\circ}C$.

For a thermocouple,the neutral temperature is $270^{\circ}C$ when its cold junction is at $20^{\circ}C$. What will be the neutral temperature and the temperature of inversion when the temperature of the cold junction is increased to $40^{\circ}C$?
