Patent attributes
The present disclosure relates to a radar-based fill-level measurement device for measuring a fill level of a fill substance located in a container. Besides a housing, the device includes an antenna and a housing neck, which is arranged between the housing and the antenna, wherein the housing neck has between the housing and the antenna a predefined thermal resistance, and at least one electronics module partially arranged in the housing neck. The thermal resistance of the housing neck is dimensioned in such a manner to be low, such that, at a temperature in the container of at least 200° C., the temperature at the electronics module is limited to, at most, 80° C. Thus, a high resolution and temperature-resistant and simultaneously compact, fill-level measurement device is provided for high radar frequencies of, for example, 79 GHz.
