Question 1 a) List two advantages and two disadvantages in using thermocouple as temperature [2 marks]...
1. a. The thermocouple shown in Figure la yields an output voltage of 7.947 mv. What is the temperature of the measuring junction? b. The ice bath that maintains the reference junction temperature melts, allowing the reference junction to reach a temperature of 25 C. If the measuring junction of (a) remains at the same temperature, what voltage would be measured by the potentiometer? c. Copper extension leads are installed as shown in Figure 1b. For an output voltage of...

Experimental methodology Problem 3 (25 pts.) A J-type thermocouple is calibrated against an RTD standard to within £0.02°C between 0° and 200°C. The emf is measured with an A/D converter having a resolution of 0.075 mV. The reference junction temperature is provided by an ice bath. The calibration procedure yields the following linear equation: T(°C) = 0.11 + 19.2V ,where the units of voltage Vis mV. This first order curve fit has an error of 0.5°C. Part a) 15 pts....
