Abstract: An antenna array for a measuring device, having an antenna with an emission surface, and an antenna holder for pivotably fastening the antenna to a fastening apparatus for the purpose of arranging the antenna array on a container or another fastening possibility, for example via a material heap, wherein the antenna holder is connected to the fastening apparatus by means of a clamping arrangement, wherein the antenna holder is in the form of a spherical layer of a sphere wherein the spherical layer has top and bottom surfaces running parallel to one another, and contains the center of the sphere, and the emission surface is arranged inside the spherical layer.

Abstract: The invention is a horn antenna for a radar measuring device, particularly a radar level gauge, with an antenna horn emitting at the front in a primary direction of emission, showing a rear feed, a fastening arrangement for the sealing fastening at a container, and an at least partial filling of the antenna horn with a solid substance, with the antenna horn being embodied at least in two parts with a first part at the device side and a second part at the container side.

Abstract: The invention relates to a radar level gauge comprising a signal generator for generating electromagnetic waves and an antenna for emitting the electromagnetic waves in a container and for receiving electromagnetic waves reflected by the container. The radar level gauge also comprises a safety device for verifying the functional capability or for improving the measuring quality of the radar level gauge, said safety device having a reflector and an adjustment device and/or a reduction device and being suitably designed to adjust the reflector and/or the reduction device at least between a first position, in which the reflector reflects the electromatnetic waves and a second position, in which the reflector reflects the electromagnetic waves in a reduced manner. The safety device also has at least one additional sensor for detecting a measured variable in the container.

Abstract: Disclosed is a pivotable horn antenna intended for a radar level indicator and includes a ball joint, the joint socket of which can be screwed into a threaded hole in the container. This allows for optimisation of the echo signal and correction of slanted installation of the horn antenna.
