摘要 |
Position detector (1), particularly for electrical valve actuators, comprising a disk (2) fixedly connected to an actuator and provided with a mapping defining a reference for detecting the actuator displacement; and means for detecting the actuator displacement by said mapping. Said mapping is formed by a plurality of permanent magnets operatively arranged along the disk (2) circumference, the polarity of each magnet being opposed to the polarity of two immediately adjacent magnets.
