Abstract

A radar measurement device for filling level monitoring and / or limit level monitoring includes: a radar signal source (102), which is configured to generate, transmit and / or receive radar signals; anantenna device (104), which is configured to align the radar signal; a plano-convex lens (106), which has a plane particularly facing the filling material, and the plano-convex lens is configured forfocus on the radar signal. The plane (110) of the plano-convex lens (106) is designed as a contact surface (112) so as to be placed on the container (108) during the measurement of the filling level and / or limit level of the filling material in the container (108).

Description

technical field [0001] The invention relates to a radar measuring device for filling level monitoring and / or limit level monitoring, a method for installing a radar measuring device and a radar measuring assembly. Background technique [0002] Various radar sensors are used in process automation to determine fill and / or limit levels. In some applications, radar sensors can be used to measure through the vessel wall. This can be achieved by a radar sensor which is arranged at a defined distance from the container in order to determine the fill level or limit level in the container. Furthermore, the distance between the antenna of the radar sensor and the container should be chosen such that the container is located in the far field of the antenna. In particular, it is advantageous that an approximately planar wave front is formed before the wave penetrates the container wall. Due to the desired distance between the radar sensor and the container wall, the arrangement may t...
