Abstract
In this paper, we propose a novel portable multi-frequency embedded sensor system for eddy current assessment of metal pieces, which is capable to realize in-situ measurements over a wide frequency range. The aim of the sensor system is to measure characteristic changes in conductivity and permeability in regards to working distance between sensor coil and work-piece. Thus, realizing a noncontact in-process measurement with a maximum standard deviation of 0.013 μH. The obtained data of the electric and magnetic parameters can be used to analyze mechanical state and phase transitions of the material [1].
