Ivanchenko A.V. Perfecting of the devices for the heat control of the substance composition by using the sensors with the p-n barrier. - The Manuscript. The dissertation on competition of a scientific degree of the candidate of technical science for speciality 05.11.13 - devices and methods for the control and determination of the substance composition. - Kiev State University of the Technology and Design, Kiev, 2001. In dissertation the basic temperature sensitive parameters and values of measuring currents of sensors for systems of the thermal control of a structure of substances are certain. Is offered new method of measurement of temperature by sensor with р-n barrier. The algorithmic method of definition of voltage drop on a fissile part of semiconducting sensors is designed which allows to eliminate effect of voltage drop on a passive part and on volumetric bulwarks of electrodes in systems of a remote monitoring of a structure of substances. The multipoint systems of the thermal control of a structure and parameters of substances with semiconducting keys - sensors are designed, in which the effect of resistance of conductors, transient resistance of keys, cubic resistance of sensors, and also instability of parameters р-n barrier is eliminated. The efficiency of offered methods and means of measurement is justified theoretically and is en-dorsed experimentally. The outcomes of activity are inserted during fulfilment research and development works in State technological firm "RADICAL" of the Ministry of industrial policy of Ukraine and in State academy of light industry of Ukraine. Keywords: the thermal control of a structure of a liquid and gas, multipoint monitoring system, semiconducting sensor, р-n transition, redundant measurements, temperature.
