Capacitive turn angle indicator
First Claim
1. Capacitive angular displacement or turn angle indicator, comprising a stationary supporting plate fastened to an apparatus;
- a movable supporting plate which is rotatable in plan-parallel relationship with said stationary supporting plate being a close spacing therefrom, said plates including oppositely located narrow sector-shaped electrode pattern;
a bearing means for the rotatable supporting plate being fastened to the apparatus; and
compressively-stressed spacer retainer means in the region of the outer rims of said supporting plates and extending in parallel with the axis of rotation for said movable supporting plate guiding said plates relative to each other.

Abstract
A turn angle indicator or angular displacement indicator and, more particularly, relates to a capacitive turn angle indicator, especially a positioning sensor for a flap or throttle valve, including a supporting plate fastened to the apparatus at a close narrow distance in front of a further supporting plate which is rotatable planar-parallel relative thereto and which is utilized for a mutually oppositely located narrow spoke or sector-shaped electrode pattern, and with a bearing structure for the rotatable supporting plate and which is fastened to the apparatus. The supporting plates are guided relative to each other through the intermediary of compressively-loaded distance spacers which are arranged in the region of the outer edges of the plates which extend in parallel with the axis of rotation of the rotatable plate.
