An inductively operating sensor, particularly for measuring distances and positions of a metallic object, comprising at least a coil, a ferromagnetic or ferritic core and perhaps a housing comprising a sensor element, with the core being embedded in a single or multi-layered ceramic and jointly with the ceramic forming a coil body and with the coil body and the core being connected to each other in a form-fitting fashion. Furthermore, a method is suggested for producing such a sensor.

Sensor and method for producing the sensor

A method for calibration of a thickness gauge is provided in which the thickness gauge measures the thickness of a measured object in a stipulated measurement direction with at least one displacement sensor, operating contactless or by scanning, a reference object with known thickness and shape being brought into at least one partial area of the measurement field of the at least one displacement sensor.

Method for calibrating a thickness gauge

The invention relates to a contactlessly working eddy current sensor, particularly for detecting essentially flat test objects, comprising at least one sensor coil, eddy currents being able to be induced in the test object. The invention is characterized in that the coil, when passing by the test object, is aligned in such a manner that the coil axis is oriented essentially parallel to a line normal to a surface to the test object, and that the test object can be moved past the sensor coil essentially parallel to the coil axis or the sensor coil can be moved past the test object. A corresponding method is carried out so that an eddy current can occur only once when the test object or coil is passed by.
