Non-contact method of three-parameter measuring control of physico-chemical characteristics of a sample of a ferromagnetic liquid

Purpose. The aim of the article is to investigate the method of three-parameter control of a sample of a ferromagnetic liquid, the realization of which is carried out on the basis of a noncontact transformer electromagnetic converter (TEC) with samples of ferromagnetic liquids in a longitudinal magnetic field. Methodology. We used a technique for studying samples of a ferromagnetic liquid for the realization of a three-parameter electromagnetic method for measuring the physical and chemical characteristics of ferromagnetic liquids based on thermal TEC. Findings. The three-parameter method of measuring control of the relative magnetic permeability µr, the specific electrical conductivity σ, and the temperature t of a sample of a ferromagnetic liquid, which is monitored on the basis of measurements and analysis of signals of a thermal contactless three-parameter TEC, is studied. Originality. The theoretical principles of the operation of a contactless thermal TEC with a sample of a ferromagnetic liquid are based on the realization of a three-parameter method for measuring the monitoring of magnetic, electrical, and temperature parameters. Practical value. The implementation of the proposed three-parameter method based on the contactless thermal TEC is performed for the operational monitoring of the physical and chemical characteristics of magnetic fluids during their manufacture and operation, taking into account rational quality criteria
