Abstract (en)

[origin: DE19757689A1] The invention relates to an inductive measuring transducer for determining the position of a body which can be displaced in relation to an immovable housing. The invention is characterized in that the movable body comprises a measuring transducer which generates a magnetic alternating field extending across a limited area and in that said alternating field permeates at least one conductor loop which is connected to the housing and extends along the measuring length. The differential voltage between the forward and feedback lines is averaged by an electric circuit and fed to an output. Said inductive measuring transducer is used by a system for measuring angles between an immovable housing and a shaft.
