В известном способе определ ют величину угла смачивани жидкости,по которой суд т о качестве магнитной обработки. Однако он не позвол ет получать однозначные отсчеты из-за неравномерности нанесени капель жидкости и изменени параметров окружающей среды, кроме того, этот способ не технологичностью и не пригоден в услови х автоматизированного контрол .In a known method, the magnitude of the wetting angle of a liquid is determined, by which the quality of the magnetic treatment is judged. However, it does not allow to obtain unambiguous readings due to the uneven application of liquid droplets and changes in environmental parameters; moreover, this method is not manufacturability and is not suitable under conditions of automated control.

Claims

A method for controlling the quality of magnetic processing is implemented as follows. 393 A three-electrode capacitor design was adopted as the primary measuring transducer (sensor). The use of steatite insulators, stainless steel and an electrode mount in three places ensured the stability of the sensor parameters during multiple heating cycles up to, To determine the measurement of the dielectric loss tangent, an automatic digital bridge of the P-589 type is used. The bridge error in the tracking mode is ± 2 10. To determine the electrical resistance, DC bridges are used. These measuring tools allow you to fully realize the advantages of a three-electrode capacitance sensor and measure only direct conductivity without taking into account private conductors on the instrument housing. In particular, a commercially available P-tOSO type bridge is used, since the resistance of the developed sensor does not exceed 10 Ohms. The determination of the dependence of the dielectric loss angle in the temperature range of 20–200 ° C showed that the maximum of the tangent value significantly depends on the condition of the magnetic treatment and clearly differs between the original sample and after its magnetic treatment (Fig. 1). Additionally, the dependence of the electrical resistivity on temperature is determined (Fig. 2). It can be seen that with increasing magnetic field strength, the value of electrical resistivity decreases. After these measurements have been made, the quality of the magnetic treatment is judged by the magnitude of the maximum dependence of the tangent of the dielectric loss angle, taking into account the minimum value of the electrical resistance of the liquid. The application of the proposed method for controlling the quality of the magnetic treatment of a fluid makes it possible to increase the accuracy of control, reduce the effect of changes in the parameters of the external medium and, as a result, intensify the processes of the petrochemical industry. The Invention Method A method for controlling the quality of a magnetic treatment of a liquid, including a magnetic treatment of a liquid, characterized in that, in order to improve the accuracy, the liquid is heated to 20-200C, while the quality of the magnetic processing is judged by the maximum value of the dielectric loss tangent and the minimum value fluid resistance.
