Abstract

An inductive measuring transducer having bodies movable relative to one another, one of the bodies being a sensor component including an inductive sensor that produces an alternating magnetic field. Another of the bodies is a pickup component including an inductive pickup into which the alternating magnetic field is injected. The pickup component includes a conductor loop in which the inductive sensor induces a voltage. A voltage curve independent of position of the sensor component relative to the pickup component develops over the conductor loop. Resistors have first ends connected along the coductor loop and second ends connected together in groups at connection points. Voltage can be picked off from the connection points that correspond to functions of the position of the sensor component relative to the pickup component and permit the position to be clearly determined, the position and value of the resistors defining the functions of the position.
