Abstract
An apparatus for inductive temperature sensing comprises a coil configuration, a target, and an impedance measurement circuit. The target has a non-zero conductivity and susceptibility and the impedance measurement circuit measures the apparent inductance of the coil configuration at a measurement frequency close to the crossover frequency to provide an indication of temperature of the target.
