Abstract
A fill level measuring device working with microwaves is provided, with which, with very small inventory cost, many applications having a wide variety of different measuring conditions can be handled. The device includes a modularly assembled antenna, having a cylindrical segment closed at one end. A sending and/or receiving element for microwaves is arranged in the segment. A thread of fixed, predetermined diameter is provided on the open end of the segment. The antenna additionally has a radiating and/or intake element, on whose end facing the segment is provided a thread of the fixed, predetermined diameter. Optionally, the antenna has one or more cylindrical functional elements between the segment and the radiating and/or intake element, which have on both ends, in each case, threads with the fixed, predetermined diameter. The segment, the optional functional elements and the radiating and/or intake element are screwed together by means of the threads.
