A length measuring system that includes a length measuring device and at least one mounting element, which exerts an attractive force between a support and the length measuring device. One or more of the at least one mounting element are of such a size that a frictional force, which is a function of a total attractive force, assures on one hand an adhesion of the length measuring device to the support and, on another hand, also assures displaceablity of the length measuring device along the support during mounting. |
