POTENTIAL SEPARATION FOR FILLING LEVEL RADAR

摘要

For safety reasons the potential of an electrical supply line of a radar sensor should be separate from the potential of the filling level container. According to one embodiment of the present invention an arrangement for potential separation for a filling level radar is provided, which arrangement comprises a separation element for insulating the waveguide from the antenna, wherein the separation element, corresponding to the cross section of the waveguide, is ring shaped. In this way rotatability between the sensor housing and the antenna subassembly is provided without influencing the signal line between the antenna and the waveguide.
