ABSTRACT:
A measuring instrument for contactless determination of an angle of rotation of an adjusting shaft. To avert transmitting a tumbling motion from the adjusting shaft to the measuring instrument, a coupling body is provided, which with engagement protrusions, engages engagement grooves of a driver body with play. The driver body actuating the measuring ring is as a result decoupled from tumbling motion effected by the adjusting shaft. The measuring instrument is especially suitable for contactless determination of the angle of rotation of a throttle device in an internal combustion engine.
