Abstract
An inductive measuring device comprises a rotor and a stator, each of which has an electrical conductor mounted thereon. Opposed grooves are formed in the conductor side of the stator and the rotor, the slip rings and contact brushes are mounted in respective grooves such that both the slip rings and the contact brushes are mounted internally between the rotor and the stator, thereby protecting the slip ring and brushes from damage and fouling and reducing the size of the measurement device and the need for external adjustment.
