Angle-position is determined by relative angular rotation between a capacitive track and a capacitive pick-up probe. The capacitive track is disposed along the region of angular interest. The pick-up probe is oriented broadside to the capacitive track and closely spaced therefrom thus establishing a measurable capacity thereacross. As the capacitive track moves angularly relatively to the pick-up probe, a geometric asymmetry is produced therebetween causing the capacity that exists thereacross to change unambiguously and in a manner that exhibits analog correspondence with relative angular rotation.
