  • Patent number: 8138753
    Abstract: A measurement system for detecting a rotary movement of a rotor that is situated in particular in rotatable fashion in a compressor housing of a jet engine, includes the rotor having vane elements that are preferably situated equidistant from one another on its periphery, and in addition at least one sensor being provided, and at least one material measure being fashioned on the rotor that can be periodically detected by the sensor due to the rotational movement, the material measure is formed by at least one modified vane element that is truncated in the area of the vane tip, the sensor outputting an identical measurement signal in each case when the vane elements travel past, and outputting a modified measurement signal when the modified vane element travels past.
