Microprocessor moisture measuring device of bulk materials based on the capacitance transformer with cylindrical electrodes

The construction of a moisture transformer device consisting of four electrodes that allow increasing accuracy of moisture measurements of grain and grain products up to 0.5% has been proposed. The proposed device in the laboratory conditions has been tested in comparison to other known transformer types. The carried-out analysis of the experimental results showed that in all used transformers we observe the disperse growing of grain degrees when rain moisture is increasing. The results obtained for moisture less than 11 % are similar practically to each other. When the moisture is growing this similarity is breaking.
