A1.2 - Impedance Model of Eccentric Coil-Target Arrangements in Eddy Current Techniques

J. Weidenm├╝ller, M. Heidary Dastjerdi, Ch. Knopf, J. Himmel & O. Kanoun
Eddy current techniques are successfully applied over a wide application field in NDT (Non Destructive Testing), such as measurement of position, displacement, vibration, proximity and alignment. Nevertheless, this technology is not established for monitoring tasks in hot rolling mills. A desired application is the mass flow control of the semi-finished product (rod) during the rolling process. Between the rolling stands, the cross-sectional geometry (x-y plane) of the rod and its speed (z-axis) are of interest....
