Background. The stage of determining the performance of information and measuring system elements is an integral part of the design process, on the basis of this stage it is possible to obtain a transfer function and determine the error of the information and measuring system (IMS). The purpose of the presented calculation and analysis of the electrical equivalent circuit elements is to determine the effect of the sensor magnetic shunt on the parameters of the phase sensor electromagnetic system (EMS).
Materials and methods. As a research method the mathematical modeling was used, in which real physical processes were described by corresponding analytical dependences.
Results. During the research the analytical expressions for the calculation of the EMC windings electrical parameters are determined, it is proved that the phase sensor windings located on the information line do not have an inductive connection with each other, the values changing relations of the electrical circuit elements when moving the magnetic shunt along the information line of the sensor are established.
Conclusions. The put design solutions of the linear motion phase sensor provide the linear dependence of the equivalent circuit inductive parameters on the measured displacement, which is an obvious advantage of the investigated IMS.
