The development of any manufacturing industry is not possible without the rational use of resources, so it is difficult to imagine modern production in which dosing is not used. The accuracy and productivity of dosing equipment is the basis of all known technological processes, since the quality of the final product depends on it. Belt feeders are small-sized and highly productive equipment, which is a vital necessity of continuous technological processes.
The main requirement for a belt feeder is the maximum possible accuracy at an already set speed of movement of the load (line productivity). However, one should not forget about the peculiarities of the behavior of different types of products that can be weighed.
The weighing accuracy of a belt feeder also depends on its design features, namely on the accuracy of the drive, tension or support rollers, the quality of the belt, and the design of the strain gauge assembly.
Experiments on calibration in statics and the behavior of the feeder in dynamics will allow us to evaluate possible behavior options during operation in real conditions.
The purpose of the experiments is the initial setup of the experimental setup for further research into the relationship of belt speed / product type / dosing accuracy.
The article describes the structure of the experimental setup, the composition of the measuring part of the laboratory setup, as well as the methodology for collecting and processing experimental data.
The main attention of the experimental part is paid to the dynamic mode of operation and its impact on the strain gauge assembly. The main issues that arise in the dynamic mode are outlined, namely
Special attention is paid to the dynamic feed mode, in which the loads on the measuring element – the strain gauge sensor – change. The key problems that arise in this mode are indicated: fluctuations in the output signal (change in mass values), the influence of the product movement speed, the physical and mechanical characteristics of the product. The results of the experiments are the voltage/mass curves in the static mode and voltage/mass/speed in the dynamic mode, a comparative analysis of the measurement results.
According to the research results, an adaptive control system for a belt feeder will be developed, which can be implemented in all industries where belt feeders are used.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
