Abstract
The travel measuring system serves to detect a control position of one body relative to another body. Disposed on one of the bodies is a coil and a structured material that influences the inductance of the coil is disposed on the other body. The influence of the material varies along a travel distance to be measured. This serves to ascertain the control position. The travel measuring system according to the invention may be used in a shock absorber to ascertain a stroke.
