Multi-frequency inductive system for magnesium level detection in a titanium reduction reactor

The inductive measurement of the magnesium level in a titanium reduction reactor is a challenging task because the state of the art measurement techniques are hampered by the formation of titanium sponge rings within the reactor. By distorting the magnetic field between excitation and sensor coils, which is used to determine the magnesium level, these rings lead to a considerable measurement error. We present a novel approach to magnesium level detection using the existing infrastructure of the titanium reduction reactor, while considering the unknown size, position and electrical conductivity of the titanium sponge ring. Based on numerical simulations, we demonstrate how to solve the resulting inverse problem by applying a look-up-table method comprising tens of thousands of pre-calculated parameter combinations.
