Abstract

One measures the velocity and the displacement of an object, for example casting velocity and casting length in the continuous casting of a steel string (11) in the tough environment. In the direction of movement of the object (11), along the movement or opposite the movement, one sweeps an eddy-current inducer (12) a predetermined distance over a surface of the object with the sweep overlapping the preceding sweep and compares the received signal, that defines the topography of the surface, with the signal in the preceding sweep by means of correlation analysis so as to get the displacement that has occurred between the steps. One gets also a measurement of the friction in the mould by registering variations in the oscillation superimposed to the string as a result of the oscillation of the mould.
