ABSTRACT:
A device for sealing a slit in the housing of an encapsulated instrument through which passes a follower for mechanically connecting an object to be measured with the measuring instrument. The slit in the instrument housing is sealed by a slotted tube, with overlapping flanks, running the length of the slit. An enlargement on the follower in the form of an ellipsoid clings to the interior of the tube walls and extends beyond the opening in the tube created by the passage of the follower, thereby maintaining a seal.
