Adequacy and Robustness Analysis of the Capacitive Moisture Meters' Static Function

Moisture content takes a special place among food quality factors as a parameter that changes during the processes of storage and processing, and, in many cases, determines consumer properties of different food products. Modern grain moisture meters' uncertainty is restricted to not more than 3 % of relative full scale error. Main task of the research is to receive robust linear static function for the grain moisture meter with four capacitive sensors. Robustness of new static function had been checked with a help of dispersion analysis. It was possible to conclude that values of repeatability and adequacy dispersions for new linear static function are approximately three times smaller, so as F-test values are seven times smaller in comparison with initial static function of a moisture meter, what proves its' better robust properties.
