Abstract
An inductive measurement transducer for determining a position of a moving body, comprising: a conductor loop over the moving body; a stationary conductor loop which extends over a measurement length and is fixed with respect to the moving body; an inductively acting element mounted to the moving body to produce an alternating magnetic field which extends essentially at right angles to the conductor loop over the moving body so that the alternating field passes through the stationary conductor loop, a voltage difference between a forward line and a return line of the stationary conductor loop being averaged and passed to an output so that voltage elements can be tapped off by individual taps which are distributed over the measurement length on the conductor loop; and one of individual resistors and individual capacitors operatively arranged to carry out the averaging, the one of individual resistors and individual capacitors being connected to a common connection which encloses the region through which the alternating magnetic field of the moving, inductively acting element can flow.
