The indicator body (11) indicates the position of a piston and incorporates on one side (12) an indicator with signal conduits and a casing, the indicator being directed towards the cylinder interior. The casing has a circular cylindrical outer shape and an outer thread (13) along the main part of its axial extent for working in conjunction with a corresp. thread in the radial hole. The casing also has two axially separate ring tracks (14,15), each of which is shaped to accommodate an axial seal. |
