摘要：A sensor system () for measuring the rotational speed of a rotatablecomponent having a pole wheel () comprising a carrier () with at least one path of
alternating magnetic north and south poles (), and at least one magnetic field sensor ()for sampling the path of the pole wheel () is provided. The sensor system () provides thatthe rotational direction in front of and behind the magnetic field sensor () a
ferromagnetic flux-conducting component () is arranged in each case opposite the path,the ferromagnetic flux-conducting components () being arranged in the installation spacebetween the magnetic field sensor () and the pole wheel (), the distance between theferromagnetic flux-conducting components () corresponding to the width of onemagnetic pole () of the pole wheel ().
