Abstract
A method and a device for non-contacting measurement of the measures and position of objects of electrically conductive materials based on electromagnetic induction is provided. A measuring object, a transmitter coil and a receiver coil are placed in relation to each other such that a time-varying magnetic field generated by the transmitter coil at a measuring region of the measuring object is substantially parallel to the surface of the measuring region. The receiver coil is placed such that a conceived field line which touches the measuring region in its extension reaches the receiver coil. On the basis of the voltage induced in the receiver coil, the position and dimensions of the measuring region relative to a given reference point can be calculated.
