Inductive measuring transducer

An inductive measuring transducer having bodies that are movable one relative to the other, one of such bodies (sensor component 2 ) comprising at least one inductive sensor ( 6 ) that produces an alternating magnetic field, and the other body (pickup component 1 ) comprising one or more inductive p...

Zusammenfassung:An inductive measuring transducer having bodies that are movable one relative to the other, one of such bodies (sensor component 2 ) comprising at least one inductive sensor ( 6 ) that produces an alternating magnetic field, and the other body (pickup component 1 ) comprising one or more inductive pickups into which the alternating magnetic field of the inductive sensor(s) ( 6 ) is/are injected, there being provided an electronic circuit ( 3 ) for supplying the inductive sensor ( 6 ) with an alternating current and a circuit for evaluating the output voltages of the measuring transducer, is characterized in that the pickup component ( 1 ) comprises a closed conductor loop ( 10 ) in which the one or more inductive sensors ( 6 ) of the sensor component ( 2 ) induce(s) a voltage so that a voltage curve independent of the position of the sensor component ( 2 ) relative to the pickup component ( 1 ) develops over the conductor loop ( 10 ), and that resistors ( 11 ) are connected along the conductor loop ( 10 ), which have their other ends connected one to the other in groups ( 12 . . . 15 ) so that voltages can be picked off from the connection points of the resistor groups that correspond to functions of the position of the sensor component ( 2 ) relative to the pickup component ( 1 ) and permit the position to be clearly determined, the position and value of the resistors ( 11 ) defining the functions of the position.
