ABSTRACT:
Inductive position determining device which comprises a signal winding having meander curves which extend at right angles to the direction in which displacement is determined and two pick-up windings which have corresponding meander curves. The meander curves have a given width and the meander curves of the two pick-up windings show intervals of increased width in which at least one of the meander curves of the other pick-up winding is accommodated. By special proportioning of the limbs of the meander curves the mean medians of the limbs of the two pick-up windings coincide. As a result the position determining device becomes largely insensitive to rotation errors between the carriages on which the signal winding and the pick-up windings respectively are placed.
