Problem Statement: A simple thermocouple circuit, which is composed of type-J thermocouples, is used to measure the temperature of a gas. The open circuit voltage, Vo, oscillates in a sinusoidal fashion with a mean of 4.997 mV, an amplitude of 0.541 mV, and a frequency of 2.1 Hz. The measurement system has the time constant t= 1.7 s. The reference junction temperature is measured with a platinum RTD (a =0.003927 C) where R=1.0275 and Ro = 1.00002 with To = 25 C. A Measurement Junction Reference Junction R B B q Platinum RTD Calculate the following quantities: (a) The mean gas temperature. The amplitude of the fluctuating gas temperature. (b) Assume that Vo = 0.0539 T for a simple type-J thermocouple circuit referenced to 0 C, where Vo is in mV and T is in C (this is from a linear curve fit to data in Table 8.6).
