Temperature of cold junction in a thermocouple is \(10^{\circ} \mathrm{C}\) and neutral temperature is \(270^{\circ} \mathrm{C}\), then the temperature of inversion is
- A \(540^{\circ} \mathrm{C}\)
- B \(530^{\circ} \mathrm{C}\)
- C \(280^{\circ} \mathrm{C}\)
- D \(260^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(B) \(530^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
Temperature of inversion is \(\begin{aligned} & T_i=2 T_n-T_0 \\ & \therefore \quad T_i=2 \times 270-10=530^{\circ} \mathrm{C} \\ & \end{aligned}\)
