Abstract:
1. A radar level gauge system, for measuring a filling level of a content contained in a tank, said radar level gauge system comprising: a transmitter arranged outside said tank and configured to transmit microwave energy; a probe at least partly disposed inside said tank and configured to guide transmitted microwave energy toward said content; a receiver arranged outside said tank and configured to receive reflected microwave energy; and a coupling configured to: wherein said coupling comprises: a mechanical connection configured to mechanically connect said probe to said tank; an electric feed-through configured to electrically connect said probe to said transmitter and receiver; and wherein said coupling is adapted to provide mechanical separation between said mechanical connection and said seal, and to permit at least some movement between said mechanical connection and said seal, thereby protecting said seal from forces acting on said probe; and wherein said electric feed-through comprises at least two conductors being connected by an electrically conductive flexible member adapted to absorb movement resulting from forces acting on said probe.
