摘要： In an inductive sensor device, and a method for inductive identification, a first and a second exciter inductor 16a, 16b extend along a measurement range and vary spatially differently from each other. A first and a second inductive coupling element 12a, 12b couple a signal from the exciter inductors 16a, 16b into a receiver inductor 18. The inductive coupling elements 12a, 12b are formed as resonance elements with a first resonance frequency f1 and a second resonance frequency f2. In order to be able to simply determine the position of both inductive coupling elements quickly and accurately, the two exciter inductors are driven by different transmission signals S1, S2. Each of the transmission signals includes signal components of a first carrier frequency near the first resonance frequency f1 varying in temporal progression, and of a second carrier frequency near the second resonance frequency f2 varying in temporal progression.

摘要： In an inductive torque sensor, two rotatable rotor elements (114a, 114b) are mounted axially and adjacent at a distance from the shaft components (112a, 112b) of a shaft (112). An inductive coupling element (18) is mounted about the circumference of each of the rotor elements (114a, 114b). An inductive circuit (30) with at least two inductors (34a, 34b, 34) on a stator element (120) extends along a sensor area so that, when the rotor elements (114a, 114b) rotate, the inductive coupling elements (18) are displaced along the inductors (34, 34a, 34b), causing a position-dependent inductive coupling between the inductors. Cost-effective manufacture is possible if the inductive circuit (30) is so mounted that with the inductive coupling element (18) it covers both rotor elements (114a, 114b). The inductive coupling elements (18) thus possess distinguishable inductive coupling characteristics.
