A method for determining the position and/or change of position of a measured object relative to a sensor, where the sensor preferably has a sensor coil to which an alternating current is applied, is characterized in that a magnet associated with the measured object, in a soft magnetic foil, whose permeability changes under the influence of a magnetic field on the basis of the magnetic field's field strength and which is arranged in the area of influence of the sensor, brings about a change in the permeability of the foil and in that the change in the permeability of the foil is determined from the latter's reaction to the sensor, and this is used to determine the position and/or change of position of the measured object relative to the sensor. A sensor arrangement is designed accordingly.

TEMPERATURE-MEASURING DEVICE AND METHOD FOR MEASURING TEMPERATURE
A temperature-measuring device comprises at least two solids with different coefficients of thermal expansion, wherein the solids have a fixed point and expand differently with respect to the fixed point in the event of a change in temperature. In addition, at least one sensor is provided for the purpose of determining the change in length of the solids in the temperature profile, wherein a processor is used to infer the respective temperature by means of the difference in the linear expansion. A method is designed accordingly.

A method for calibrating a thickness gauge, wherein the thickness gauge measures the thickness of a measurement object in a predefinable measuring direction (Z), comprising at least one displacement sensor (1, 2) operating in a contactless or scanning manner, wherein a reference object (3) having a known thickness and shape is moved into at least a partial region of the measurement field of the at least one displacement sensor (1, 2), comprises the following steps with respect to particularly precise and simple calibration. First, at least two independent measurement values are recorded by the at least one displacement sensor (1, 2) in at least two predefinable sites on a first surface of the reference object (3) at predefinable times tj, or as a function of predefinable positions pj of the reference object (3) in the measurement field, where j = 1, 2... Then the tilting or spatial position of the reference object in the measurement field is determined based on the measurement values recorded at the times tj, or as a function of the positions pj of the reference object (3). Then, a further measurement value is recorded by the at least one displacement sensor (1, 2) at a further site located in the measuring direction (Z) on a second surface disposed opposite the first surface, or on a surface region of the reference object (3) disposed opposite the first surface, in order to determine a thickness value of the reference object (3) in the measuring direction (Z). Then, the thickness value of the reference object (3) is calculated from the measurement values of the at least one displacement sensor (1, 2) at the times tj or in the positions pj in the measuring direction (Z). Finally, the difference between the calculated thickness value and the known thickness of the reference object (3) is calculated in order to obtain position and tilt or location-dependent corrective values in the partial region or measurement field, in order to compensate for geometric errors and/or non-linearities of the at least one displacement sensor (1, 2) in the partial region or measurement field during thickness measurement.
