c) A thermocouple with a time constant of 0.3 sand a static sensitivity of 0.04 mV/° C is suddenly immersed in a bath of hot oil, which is at 1 00 °C. The initial temperature of the thermocouple measuring and reference junctions was 25° C. i) What is the output at t = 0.1, 0.3 and 1.0 s? 5 Marks ii) Design a compensating circuit to be used along with the thermocouple so that the time constant is reduced to half its value. For this system, find the output at t, given in (a). 4 Marks c) A thermocouple with a time constant of 0.3 sand a static sensitivity of 0.04 mV/° C is suddenly immersed in a bath of hot oil, which is at 1 00 °C.
