Abstract
A transmitter system for a Ferraris motion transmitter, includes a magnetic measuring arrangement including at least one magnetic field generator for generating a magnetic field and an electrically conductive measuring body, with the magnetic field generator and the measuring body movable relative to one another in operation. Coupled to the magnetic measuring arrangement is a magnetic field sensor for providing an output signal commensurate with a velocity or acceleration of the measuring body. At least one of the magnetic field generator and the magnetic field sensor includes at least two magnetic members interlocking one another in concentric relationship to the measuring body for guiding the magnetic field as a result of eddy currents forming during operation.
