In an encapsulated measuring instrument for measuring the relative position of two objects, a scale and a scanning unit are mounted within a housing which defines a slit therein. One of the objects is connected with the scanning unit by means of a follower which extends through the slit. One or more sealing strips are provided for sealing off the slit, and each of the sealing strips includes a plurality of tightly bundled fibers.

In an encapsulated measuring device for measuring the relative position of first and second objects movable with respect to one another, said device comprising: a housing adapted to be coupled to the first object and defining a slit which extends along a measuring direction; a follower adapted to be coupled to the second object and extending through the slit into the housing; and a measuring component disposed within the housing and coupled to move with the follower, the improvement comprising: flexible covering means for sealing the slit around the follower as the follower moves along the slit, said covering means comprising at least one sealing strip which comprises a plurality of tightly bundled fibers and a thin sheet of flexible material secured between the bundled fibers to reduce permeability of the sealing lips; said fibers comprising an elastic material which generates a restoring force when deflected by the follower; said fibers comprising first and second sets of fibers, wherein the first set of fibers is positioned inside the thin sheet between the thin sheet and the follower and the second set of fibers is positioned outside the thin sheet.
