Kachanov M. Accuracy increase of measuring transducers by bulk solids humidity two-parameter control under apparent density unavoidable impact conditions.

Object of research: processes of informative transformation of output signals of resonance two-parameter of high-frequency measuring transformer of humidity of friable materials in the conditions of the irremovable factor influencing of impact conditions and метрологической vagueness of градуировочной description of transformer. The purpose of research: development of methods of increase of exactness of control of parameters of friable materials at the use of resonance high-frequency transformers. Methods of research and equipment: informative theory of measurings; the estimation of exactness of measurings transformations was conducted in accordance with the methods of theory of errors of facilities of measurings; for optimization of classification model of measuring the methods of дискриминантного analysis were utilized; for the estimation of authenticity of procedures of control of humidity methods and models of параметрического measuring control were used. The theoretical and practical results: onthe basis of the developed mathematical models of dispersion, informative and дискриминантного analysis the methods of calibrating of measuring device of humidity and choice of procedures of treatment of output signals of resonance transformer, providing a maximum of authenticity of control of humidity are offered. Novelty: statistical procedures of treatment of results of the frequent measurings got further development and analytical correlations are got for dispersion of output signals of measuring transformer; the informative criteria of choice of measuring transformation are first offered; procedures of measuring transformation of humidity are improved on the basis of кластеризации of range of measurings. A degree of introduction: LTD. is the Pharmaceutical company "Health" (Kharkov), NPO of "Ekstruder" (Kharkov). Sphere of use: entrance and technological checking of friable organic and biochemical materials systems.
