IFFERENTIAL TRANSFORMER SENSORS WITH SIMPLE STRUCTURE OF MAGNETIC CIRCUITS METHODS FOR INCREASING THE DISTRIBUTION LINEARITY OF MAGNETIC CURRENTS

In the article differential transformer sensors measuring shifts the magnetic capacitance of the air gap between two long ferromagnetic cores, which allows the linear distribution of magnetic currents in ordinary structural scattered parameter differential magnetic circuits along the length of the chain, the expressions of the change of the magnetic circuit length of the compare values of the magnetic driving forces located longitudinal. Based on the analysis of differential magnetic chains with the proposed simple structure according to these analytical expressions, it was determined that the construction of a magnetic chain is technologically relatively simple and does not require an excess of non-ferrous metal (copper) due to the fact that the air gap between two long ferromagnetic cores changes the compare value of the magnetic.
