摘要： An apparatus for determining or monitoring the fill level of a fill substance located in a container in a process, comprising: a signal producing unit; an in-coupling/out-coupling unit an antenna unit; wherein the antenna unit has a hollow conductor and an antenna element widening toward the fill substance and the antenna unit transmits high-frequency measuring signals in the direction of the surface of the fill substance and receives echo signals reflected on the surface of the fill substance; and a control/evaluation unit, which ascertains the fill level of the fill substance in the container based on travel time of the measuring signals. In or on the antenna unit a process isolation is provided, which is at least approximately transparent for the high-frequency measuring signals and which protects the in-coupling/out-coupling unit against influences of the process. The process isolation is an isostatically pressed, molded part, which is manufactured of at least two plastics having different physical and/or chemical properties.
