  • Patent number: 5339029
    Abstract: In a method for inductively measuring the position of a strip of metal, in which a primary coil fed by an alternating voltage is arranged on one side of a strip edge and a secondary coil is arranged on the other side of the strip edge and a signal reproducing the strip position is derived from the change in coupling at the secondary coil caused by the shielding by the strip, the primary coil is operated at a high frequency of the alternating voltage of at least 10 kHz in order to widen the field of application of the inductive strip position measuring. Non-magnetic coil cores are provided at primary and secondary coil in order to achieve a high natural resonant frequency.
