Abstract
For safety reasons the potential of an electrical supply line of a radar sensor may be separated from the potential of the fill level container. A fill level radar with potential separation includes a separation element for insulating the aerial from a feed device. The separation element is arranged directly at the aerial, or forms part of the aerial. In this way insulation of the aerial from the exterior of the container is provided.
