If the cold junction of a thermo-couple is kept at 0⁰C and the hot junction is kept at T⁰C then the relation between neutral temperature (Tₙ) and temperature of inversion (Ti) is
Options
(a) Tₙ = 2 Ti
(b) Tₙ = Ti – T
(c) Tₙ = Ti + T
(d) Tₙ = Ti / 2
Correct Answer:
Tₙ = Ti / 2
Explanation:
Since, Tₙ = Ti – Tᵥ / 2 = Neutral temperature
Tₙ = Ti + 0 / 2 = Ti / 2
[ Tᵥ = 0⁰C = temperature of cold junction]
