1. for a position transducer for valve module, its Position Sensor comprises:

  • Flux source, for generation of predefined magnetic field, this flux source provides a plurality of discrete magnet in a plurality of discrete magnetic fields to form by comprising, described a plurality of discrete magnet is for being placed into continuously a linear array, one of described a plurality of discrete magnet are positioned at the geometric center of the plurality of discrete magnet, and the wherein said magnet that is positioned at geometric center provides magnetic zero-bit and all the other a plurality of discrete magnet polarity in each side of described magnetic zero-bit is contrary;

    AndSensor, this sensor is placed near flux source, detects the predefine changes of magnetic field causing due to the relative displacement between flux source and sensor.
