ABSTRACT
This chapter details the experimental setup and measuring instruments, the experimental methodology and the uncertainty in the measurements. The calibration is done by immersing the thermometer and the thermocouple in a hot water bath maintained at a fixed temperature. The derived quantity power, which is a product of the voltage and current, requires an uncertainty calculation. The data logger can also measure AC and DC voltage, current, frequency, resistance and period. It has three module slots with 20 channels per slot, with each channel connected to a thermocouple. For the purpose of thermocouple calibration, a constant temperature bath is used. Thermocouples are very sensitive and require a good amplifier with a cold-compensation reference. Both the current and voltage measured by the potentiometer circuit have an uncertainty of less than 2%. The assembled wireless temperature module is integrated with the potentiometer circuit and is assembled at the top of the dynamic rotating structure.
