ABSTRACT:
A piston rod is guided with freedom of axial movement in a cylinder, where the position of the piston rod is detected by a first position-measuring device, which travels along with the piston rod, and by a second position-measuring device on the cylinder side. The two position-measuring devices are radially adjacent and axially parallel, and are supported in such a way that they cannot rotate with respect to each other.
