Radar measurement device with plane convex lens

[0034] figure 1 A plano-convex lens 106 according to an exemplary embodiment is shown. The plano-convex lens 106 has a flat surface 110 and a convex surface 114 opposite to the flat surface. In addition, the plane 110 may be fixed on the container 108. The convex surface 114 may be fixed to the antenna device 104.

[0035] figure 2 A plano-convex lens 106 according to an exemplary embodiment is shown. The plano-convex lens 106 has a flat surface 110 and a convex surface 114. In addition, the plano-convex lens 106 has a lens shoulder 124 that extends around the convex surface 114. In addition, the lens shoulder 124 may form a surface for fixing the radar measuring device 100 on the container 108.

[0036] image 3 A radar measurement device 100 according to an exemplary embodiment is shown. The radar measuring device 100 has a radar signal source 102 on which an antenna device 104 is arranged. The plano-convex lens 106 is arranged on the antenna device 104. The plano-convex lens 106 has a flat surface 110 and a convex surface 114. The convex surface 114 protrudes inward into the antenna device 104. In addition, the radar measurement device 100 has a housing 120. The housing 120 has a bottom surface 122 formed by the flat surface 110 of the plano-convex lens 106. In addition, the plane 110 of the plano-convex lens 106 has a lens shoulder 124, and the lens shoulder 124 also forms a part of the bottom surface 122.

[0037] Figure 4 A radar measurement device 100 according to an exemplary embodiment is shown. The radar measuring device 100 has a radar signal source 102 on which an antenna device 104 is arranged. The plano-convex lens 106 is mounted on the antenna device 104. The plano-convex lens has a convex surface 114 whose diameter is the same as the maximum inner diameter 118 of the antenna device 104. In addition, the radar measuring device 100 is mounted on the container 108, wherein the plano-convex lens 106 is placed on the container 108 flat. In particular, the connection between the plano-convex lens 106 and the container 108 can be established by an adhesive connection.

[0038] Figure 5 A radar measurement assembly 200 is shown, which has a radar measurement device 100 and a container 108 for containing a medium 130. The radar measuring device 100 is arranged on the container 108 through a plano-convex lens 106. The plano-convex lens 106 is a part of the housing 120 of the radar measuring device 100. Furthermore, the radar measurement device 100 has a radar signal source 102 on which an antenna device 104 is arranged. Furthermore, the radar measuring device has an energy storage 126 for supplying energy to the radar measuring device 100, which energy storage 126 is also arranged in the housing 120 of the radar measuring device 100.

[0039] Image 6 A radar measurement device 100 according to an exemplary embodiment is shown. The radar measuring device 100 has a plano-convex lens 106 that is designed to be mounted on a sealing member 128 that is fixed to the antenna device 104. In addition, the radar measurement device 100 has a radar signal source 102. The seal 128 is preferably fixed between the plano-convex lens 106 and the antenna device 104 so that no moisture or contaminants enter the antenna device 104. In addition, the radar measuring device 100 is arranged on the container 108 through a plano-convex lens 106.
