Length measuring instrument

摘要

A length measuring instrument including a hollow profile section extending in a longitudinal direction and an end piece fixed on the hollow profile section for closure of the hollow profile section on an end of the hollow profile section. A scale is disposed inside the hollow profile section, wherein the scale includes a measurement graduation which can be scanned by a scanning unit that is movable in the longitudinal direction relative to the hollow profile section. The length measuring instrument includes a sealing element on the end piece for sealing off the hollow profile section, wherein the sealing element has a cross-section that is at least extensively equivalent to an inside diameter of the hollow profile section. In addition, the sealing element rests sealingly so that a circumferential surface of the sealing element is on an inner face of the hollow profile section.

1. A length measuring instrument, comprising:
a hollow profile section extending in a longitudinal direction; an end piece fixed on said hollow profile section for closure of said hollow profile section on an end of said hollow profile section; a scale disposed inside said hollow profile section, wherein said scale comprises a measurement graduation which for position measurement can be scanned by a scanning unit that is movable in said longitudinal direction relative to said hollow profile section; and a sealing element on said end piece for sealing off said hollow profile section on said end of said hollow profile section, wherein said sealing element has a cross-section that is at least extensively equivalent to an inside diameter of said hollow profile section and said sealing element rests sealingly so that a circumferential surface of said sealing element is on an inner face of said hollow profile section, wherein said sealing element is attached to said end piece in such a way that said sealing element is displaceable relative to said end piece transversely to said longitudinal direction.
