Purpose: The purpose of this article is to study the theoretical provisions of the operation
of a vortex device in the implementation of a non-contact method of controlling the details
of brewing equipment using computer simulation algorithms.
Design/methodology/approach: The theoretical positions of thermal ECT operation with
a copper product are obtained, which is controlled while maintaining a constant value of the
magnetic field frequency f1 = 70.0 Hz, with small values of the generalized parameter x≤1.1 and
increasing the parameter x due to the increase in the frequency of thermal ECT, that is, at x≥3.5.
Findings: On the basis of computer simulation algorithms the results of the joint measuring
control of diameter d, electrical resistance ρ and temperature t of the sample made of copper
(in the temperature range from 20-160°C) and the results of determination of thermally
dependent thermal ECT signals with the sample of equipment details and the values of
specific normalized values that relate the ECT signals to the physical and mechanical
characteristics of the samples of the equipment being monitored.
Research limitations/implications: Product diameters range is 5 mm to 50 mm. The
lower boundary is limited by the frequency of the magnetic field f = 20 Hz and the upper
boundary by the diameter of the frame of the thermal eddy current transformer transducer
is 50 mm. Perspective positions of work require further development in the direction of
extending the limits of control of geometrical parameters of the samples due to the use of
automated control systems based on overhead eddy current transformer transducers.
Practical implications: The practical value of the work is to increase the overall likelihood
of control of the parameters of brewing equipment parts by increasing its instrumental
component Di, due to the reduction of measurement errors due to instrumental techniques
and on the basis of computer modelling algorithms for three-parameter control of parts of
brewing equipment, electrical and temperature parameters, allows to obtain the value of the
overall control probability Dz = 0.998.
Originality/value: The originality of the article is the study of the theoretical provisions of
the eddy current transformer transducer and the implementation of a non-contact method of
controlling the details of brewing equipment using computer simulation algorithms that take
into account the modes of joint three-parameter control: at high values of the generalized
parameter x (with three-parameter surface control), at small values of x (while controlling
the value of the average cross section geometry, electrical, temperature settings) at a fixed
frequency magnetic field (get information on the diameter d, resistivity ρ and temperature t
with a certain depth of penetration of the magnetic field in the sample Δ).
