Abstract

The paper deals with the features of induction control existing methods and facilities for the magnetic susceptibility of the medium. We draw conclusion that these facilities have a common disadvantage associated with low measurement accuracy. The ways to improve their sensitivity and measuring accuracy of the controlled parameters through inductive measuring transducers are revealed. Algorithm of the resonance control implementation for the magnetic susceptibility is developed. Its characteristic feature is the usage of specific distance value from the measuring probe to the controlled medium in the calculations, obtained by an ultrasonic distance sensor in order to reduce the influence of unevenness of the ore-bearing rock on the measuring accuracy of its magnetic properties. For the determination of the scaling factors, an appropriate calibration algorithm has been developed. It is shown that the application of the proposed algorithm makes it possible to increase the sensitivity of the facilities for the magnetite ores operative control by automatic signal processing and to provide a measurement error less than 1.5% in the extended range of distances from the probe to the medium in question, which is approximately 10 times larger than the measuring range of similar devices.
