摘要:
A measuring device working with high frequency microwaves, especially frequencies above 70 GHz, comprises a microwave module for the production of microwave transmission signals and/or for the reception and processing of received microwave signals, and an antenna unit for the transmission of the microwave transmission signals and/or for the receipt of the received microwave signals. The measuring device has a cost effective, flexibly usable connection between the microwave module and the antenna unit suitable for the transmission of high frequency microwave signals, especially frequencies of 70 GHz and more. The microwave module and the antenna unit are connected to one another via a dielectric waveguide, via which a transmission of the microwave transmission signals from the microwave module to the antenna unit and/or a transmission of the received microwave signals from the antenna unit to the microwave module occurs.

A method is based on measuring a distance to a reference reflector arranged at a known distance, in order to calibrate and/or monitor a coherent frequency modulation, continuous wave radar, fill-level measuring device, wherein the reference reflector can be reliably identified. To this end, a reference reflector executing oscillations toward the fill-level measuring device with an oscillation frequency is used, which is inserted in the beam path of periodically linearly frequency modulated transmission signals transmitted from the fill-level measuring device. The fill-level measuring device receives fractions of the transmission signals reflected back on reflectors in the container and records based on these received signals and their time correlation relative to the respectively associated transmission signal for each received signal an echo function, which shows the amplitudes of the received signal as a function of the associated position of the associated reflector. Based on the time change of a plurality of sequentially recorded echo functions and the oscillation frequency of the reference reflector, the position of the reference reflector in the echo functions is identified and its reference reflector position determined.

摘要:
An arrangement for measuring fill levels of fill substances located in containers with a single fill-level measuring device operating according to the travel time principle, and arranged removed from the measuring locations at which a fill level is to be measured and having an antenna for directed sending of microwaves and for receiving microwaves. The arrangement includes: a mirror arrangement, which has, arranged at a measuring location above the fill substance, at least one mirror, which transmits, to the surface of the fill substance, microwaves sent from the antenna in their transmission direction and which transmits, back to the antenna, their echoes reflected on the surface of the fill substance; and a measuring device electronics, which is fed, in measurement operation, received signals received with the antenna, and which, on the basis of the received signals, ascertains the travel times of the microwaves reflected at the measuring locations on the surface of the fill substance and ascertains therefrom, on the basis of the positions of the mirrors arranged above the fill substance at the measuring locations, the fill levels at the measuring locations.
