Abstract
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.
Claims4
A rotatable position detector (1), particularly for electrical valve actuators, comprising:
- a disk (2) fixedly connected to a rotating valve actuator for rotation thereby and provided with a maping defining a references for detecting the actuator displacement;
- and
- means for detecting actuator displacement by said mapping,
- characterized by the fact that said mapping comprises a plurality of permanent magnets secured to the end operatively arranged along the disk (2) adjacent the circumference thereof the polarity of each magnet being opposed to the polarity of two immediately adjacent magnets thereof.
