Current ongoing monitoring and prospects of prediction of the confectionary products state with new capacitive transducers
(2013) Tarasenko, Sergiy; Kolomiets, Dmitro; Galushko, Mykola
The capabilities of new high-precision three-contact capacitance transducers for monitoring and predicting the state of confectionery on their dielectric permittivity and electrical conductivity was described.
Electrical capacitive control of the properties of substances, transported by pipelines
(2012) Tarasenko, Irina; Kolomiets, Dmitro; Rudik, K.; Tarasenko, Sergiy
In the article considered the new class of three-terminal electrical capacitive means for control the composition of liquid and loose substances, including such transported by pipelines. Such converters are markedly different with accuracy and noise immunity of remote automated control of substances parameters. Considered and analyzed use possibilities of created design of measuring systems for automatic nondestructive integral and differential control the composition of flow substances – raw materials and semi-finished products of food production.
Method of thermometric determination of thermophysical characteristics of thermolabs materials
(2019) Mazurenko, Olga; Kharchenko, Liliya; Kolomiets, Dmitro; Mazurenko, Alexander
To study the thermophysical characteristics of thermolabial materials, the most suitable thermometric means of their complex definition, which allow to conduct research in the presence or absence of material phase transformations of its constituents. The calorimetric measuring instruments are based on the measurement of the temperature of the heat fluxes that penetrate the sample under different thermal conditions. Thermal, electric and other transmission processes in thermometric materials determine the instability of the transformation function and form an instrumental error. On the basis of the calculation and graphic analysis of the thermal and capacitive resistance of the "device-sampler" system, a fundamentally new method has been developed, according to which the thermophysical characteristics of the material and the metrological characteristics of the device are determined in a complex and simultaneously based on the results of the experiment with samples of only the test material.
