Анотація: (English) If we consider modern pharmaceutical production as an example, then in each technological tank of such production, we can find so-called dead zones, in which the processes are slowed down and their dynamics radically differs from the same processes in the active parts of the technological tank, where, as a rule, there is a circulation, developed turbulent movement of process fluids In the corners of such tanks the level of dynamic activity decreases sharply and the results of chemical reactions may differ significantly from areas with developed turbulence In order to controlthe chemical – reaction activity of the entire working volume of the technological tank and, as necessary, equalize all the main operating parameters of the process, and in addition, to ensure the same time of a high-quality technological process at all points of the working volume of the technological tank, a sensor module is formed based on modern achievements and capabilities of contactless sensor technology in the form of a sleeve, in which a sensor – solenoid is embedded, of a certain design.
