Example 3: Analysis of Thermocouple

A thermocouple has the following properties: 

r = , c_p= , = 0.0025 ft

This thermocouple is used in an application (Figure 4) where the convective heat transfer coefficient is found to be h = 7.5x10^-4 BTU/(ft²-°F-s).  A compensating circuit has been added to the thermocouple output as shown in Figure 5.  The temperature of the fluid being measured varies as T_fluid = 30 sin(wt) °F where w = 0.0035 rad/s.  Assume the thermocouple output is 1 volt per °F.

a)   Find the steady-state output of the thermocouple without the compensating network. b)   Sketch the frequency response plots of the thermocouple without the compensating network using the semi log paper on the following page. c)   Find the steady-state output of the thermocouple with the compensating network.  d)      On the plot you made for part b) sketch the frequency response plot of the combined thermocouple and compensating network.  Be sure to clearly label the curve for the system with and without compensation. e)      What has the compensator done in this problem?
