Popis: An eddy current tomography system is under development to monitor the condition of metallurgical tapholes. In this paper, the results of two approaches for solving the forward eddy current problem are presented. The results of these simulations are compared against corresponding experimental measurements taken using a custom-built measurement system and a commercial LCR meter. These comparisons showed that there was good agreement between the measured and predicted responses for both the phase angle and magnitude components of the response. Additional modelling conducted showed that the measurement system will be sensitive to the changes that will occur as the wear profile of the taphole refractory changes over time.
