Abstract
A radar level gauge system include a transceiver; an antenna; a hollow waveguide for guiding the transmit signal from a first end facing the transceiver towards a second end facing the antenna; a housing including a heat-dissipating structure arranged at a first distance from the second end; a first thermal connection between the hollow waveguide and the heat-dissipating structure; and a second thermal connection between the hollow waveguide and the housing arranged at a second distance, shorter than the first distance, from the second end. The first and second thermal connection are arranged such that a thermal resistance of a first heat conduction path from the second end of the hollow waveguide through the first thermal connection to the heat-dissipating structure, is lower than a thermal resistance of a second heat conduction path from the second end of the hollow waveguide through the second thermal connection to the housing.
