<p>The method involves producing a magnetic field by using a magnetic element of a piston (10). Measurement variables are determined by using a sensor arrangement of a pneumatic cylinder (12), where the measurement variables are correlated with the variables of the magnetic field in two different spatial directions and correspond to two different magnetic field components. Absolute values of the measurement variables are used by a difference signal in order to determine the relative position of the piston and the cylinder. An independent claim is also included for a position detector for detecting relative position of two objects.</p> |
