Abstract
A radar level gauge system for measuring a filling level of a content contained in a tank is disclosed. The system comprises a transmitter and a probe, configured to guide transmitted microwave energy towards the content. Further, it comprises a coupling comprising a mechanical connection configured to mechanically connect the probe to the tank; an electric feed-through configured to electrically connect the probe to the transmitter; and a seal adapted to hermetically seal the electric feed-through, wherein the coupling is adapted to provide mechanical separation between said mechanical connection and said seal, and to permit at least some movement between the mechanical connection and the seal, thereby protecting the seal from forces acting on the probe.
