Abstract

The invention relates to a novel type of electric inductance arrangement for a series of applications in the field of distance measurement, sensor-based detection of objects, and construction of induction machines. The novelty consists in the type of inductance arrangement of the receiver or transmitter coil, said arrangement being designed in the form of a ladder rung arrangement, wherein the ladder spars short-circuit the rungs. The sum of all the short-circuit currents is an indicator of what is occurring in the surroundings of the arrangement. This could be changing magnetic fields caused by transmitter objects or additional ladder-rung systems acting as transmitters. Multiple such sensors and transmitters can be designed in the ladder-rung form, said sensors and transmitters being connected in parallel or in series according to the application under certain circumstances and if necessary assuming the excitation function by moving a conductor through which a direct current is flowing or by applying alternating currents. The aforementioned inductance arrangement results positively in that the coils can all have a completely crossover-free design and are therefore substantially simpler to technically implement for very different applications in electrical engineering. The applicability ranges from short-range distance measuring devices and long-range object location to light detection and efficient induction machines with large or also very small constructions.
