Abstract

Temperature measurements in power generation systems can provide useful information on the performance parameters of the units. This paper presents a conceptual measurement technique using a simulated thermoelectric loop (signal transmitter). The transmitter simulates the induced current and magnetic field emanating from the center of an n and p loop. The receiver used in this study is a Hall Effect sensing device which measures the magnetic flux density produced by the transmitter. Three experimental setups were designed and built for the measurements. The first setup used a pendulum to move a coil simulating a loop thermoelectric generator thereby creating a magnetic field. A second generation setup was also constructed that produced more accurate and repeatable results. Finally, a third setup was built using a heated thermoelectric generator device (adding temperature as a new variable) in order to see the relation between the temperature gradient, the induced magnetic flux, and the Hall sensor's response. Results obtained in this study from the three generations of experiments are presented in this paper along with the filtering process utilized to reduce the noise of the signal. Results show that measurements of temperature wirelessly using thermoelectrics are feasible and may be used in future advanced power generation technologies.
