  • Patent number: 11181393
    Abstract: By configuring an encoder scale as a varying scale with successively increasing or decreasing pitch, sensors in a travel path of the scale can detect a phase difference to determine an absolute position of the scale for use in an industrial control system. Due to the successively increasing or decreasing pitch, each sensor can detect successively increasing or decreasing properties (such as magnetic fields) from the scale in a uniquely identifiable pattern. By taking the difference between readings of adjacent sensors, each sensor detecting properties of the scale, an absolute position of the scale between the sensors can be determined. The principle for feedback for the encoder system is analogous to a Nonius or Vernier principle to determine absolute position.
