A thermocouple junction of area A, mass m, heat capacity C, and emissivity e is located in a furnace that normally is at T°C. At these temperatures convective and conductive heat transfer to the junction is negligible compared with radiative heat transfer. Determine the linearized transfer function between the furnace temperature Ti and the junction temperature TO. For the case m = 0.1 g C = 0.12 cal/(g °C) e - 0.7 A = 0.1 cm? Tis = 1100°C %3D %3! plot the response of the thermocouple to a 10°C step change in furnace temperature. Compare this with the true response obtained by integration of the differential equation.
