1. A device for determining and/or monitoring at least one process variable of a medium, the device comprising:
a measuring insert, including a sensor element disposed in an end region of the measuring insert and configured to detect the at least one process variable;
a dipping body in form of a protective tube configured to receive the measuring insert and at least temporarily and/or partially protrude into the medium, wherein the dipping body surrounds the measuring insert at least in a subregion adjacent the medium in which the sensor element is disposed; and
a coupling unit adapted to be introduced into the dipping body and configured to fill an internal volume between an inner wall of the dipping body and an outer wall of the measuring insert at least in the subregion in which the sensor element is disposed as to enable a mechanical coupling and a thermal coupling between the dipping body and the measuring insert and such that no air gap exists between the outer wall of the measuring insert and the inner wall of the dipping body,
wherein the coupling unit is a solid body comprising a solid lubricant, wherein the solid lubricant is graphite, and
wherein the coupling unit is configured to be mounted inside the dipping body such that the measuring insert is removable from the dipping body without needing to remove the coupling unit.
