The structure of measuring stands of ultra-high-frequency installation of drying and baking of bricks is considered. The creation of a practical microwave installation is determined by the creation of measuring stands at a low power level, by working on electrodynamic models and by creating appropriate laboratory installations of a high power level. The measuring stand of the described structure allows to check the matching characteristics of all waveguide elements of the feeder chain, adjustment of waveguide tees, and the development and tuning of the energy input units to the microwave chamber of the experimental setup. In the laboratory installation it is proposed to use the industrial generator KIE-5, operating at a frequency of 2.45 GHz with a maximum output power of 5 kW and a waveguide ferrite circulator. The maximum power of such an installation differs only 10 times from the power of the experimental setup. This makes it possible to reliably estimate the electrical strength and heat release of the experimental unit assemblies from the results of laboratory studies.

In the article the scheme of the measuring stand of the device model for determining the part of the energy distributed from the generator, the scheme of the measuring stand of the model for measuring the standing water coefficient (VSWR) and the measurement of the transient resistance are presented. The best results are obtained by a partition consisting of two metal plates overlapping the path both above and below the clay layer. So, with a clay humidity of 4%, the total attenuation was 14.4 dB (-6.1 dB without a partition), and at a humidity of 16% -35 dB (-18.4 dB without a partition). There is an increase in attenuation of approximately two times compared to the case without a partition for both dry and wet clay, but the amount of attenuation is insufficient. To increase the attenuation in model 2, two consecutive resonators were created. But the attenuation in this case increased insignificantly in comparison with one resonator. It is obvious that two resonators are upset because of mutual influence on each other. Therefore, it is proposed in a real installation between these two resonators to place a section of a waveguide of nonresonant length with an absorber that will eliminate the coupling between the resonators.
