Abstract

In a method for adjusting a displacement sensor measuring chain using the eddy current measurement method, the aim is to achieve an improved adjustment rapidly and simply. This is achieved when a conductive and/or magnetic material (7, 8) is introduced into the stray field of the sensor coil (3), and is brought into the necessary arrangement with respect to the sensor coil (3) for the purpose of adjustment. In an apparatus for carrying out the method, a conductive and/or magnetic material (7, 8) is arranged in the region of the stray field of the sensor coil (3). <IMAGE>
