ABSTRACT:
An angular position sensor having at least one resistive track which is circular, for example, and at least one cursor. The cursor is adapted to move while in electric contact with the track. The track is closed and continuous and has at least two electric access points. The sensor cooperates with an arrangement for applying separate predetermined electric potentials to the access points and with an arrangement for measuring the resulting electric potential at one of the access points. The cursor is therefore able to rotate through a complete turn without leaving the one resistive track. All angles can be measured and rotation through several turns is possible.
