Расширение функциональных возможностей электромагнитных преобразователей с пространственно-периодическими полями

Abstract

In this paper, the questions of the theory of electromagnetic converters for multiparameter measurements with fields that are spatially periodic structure are considered. It is shown how by means of the amplitude dependence of the spatial harmonics can be positioned section measuring windings in order to select the required transmitter signal from the harmonics. Plots of the normalized amplitudes and phases are shown.The algorithm for determining the electro-magnetic and geometrical parameters of cylindrical products is given. The conclusion that electromagnetic converters allow to exercise multiparameter control due to use of a certain number of separate spatial harmonics of the probing field is made.
