The invention relates to a sensor element for an inductive sensor used for a displacement or distance measurement by means of a magnetic field that varies according to the distance from the measurement object but that remains temporally constant. In said sensor, thin ferromagnetic material is integrated into a substrate. The invention also relates to a sensor comprising said sensor element and to a method for producing the sensor element.

Inductive sensor comprising integrated soft magnetic layer and method for the production thereof

A method for detecting magnetic fields, particularly for detecting the position of objects with a preferably oblong, soft-magnetic element, which is connected to electronics, with via the electronics the impedance of the soft-magnetic material is measured, characterized in that a magnetic field is used in which by the position of an object which is located in an arrangement with the soft-magnetic material the magnetic field develops at the location of the soft-magnetic material, with the magnetic permeability &#x3bc; of the soft-magnetic material adjusting, depending on the magnetic field and thus the position of the object. A respective device serves for applying the method according to the invention.

Method and apparatus for sensing magnetic fields

Sensor with a one-layer or multi-layer sensor element operating in a contact-free manner and a housingcomprising an electric/electronic connection and, in given cases, electronic components, where the sensor element comprises a coil arrangementwhose windingshave a defined line width, line thickness, and line spacingper layerand whose layershave a defined layer thicknessand, in given cases, a defined layer spacing, characterized in that the sensor element is built up from ceramic layers in the sense of multi-layer ceramics and that with respect to traditional coil arrangements the layer thicknessor the layer spacingis reduced and the number of windings per cross-sectional surface area is increased.
