Abstract
A length-measuring device for measuring a relative position of two objects with respect to each other by scanning a measuring graduation of a scale tape includes a hollow section member in which the scale tape is tensioned along a longitudinal direction of the hollow section member. A tensioner device is configured to tension the scale tape. The tensioner device includes a fixed member which is stationary relative to the hollow section member and a tensioner which is held under tension on the fixed member by a spring acting in the longitudinal direction, as well as a holding member to which the scale tape and the tensioner are attached. The tensioner is detachably secured to the holding member and configured such that the tensioner is separable from the holding member and removable from the hollow section member at an end. An adjuster adjusts the tension of the scale tape.
