Resonance Sensors of Motion Parameters

The article studies the design features of known and developed electromagnetic resonant sensors of motion parameters and develops their mathematical models, which make it possible to study the main technical characteristics of these sensors. A comparative analysis of the obtained expressions of the output signals and the sensitivity of the known and proposed electromagnetic resonant sensors of motion parameters shows that the sensitivity of the proposed sensor due to the implementation of each magnetic field source in the form of a multi-turn magnetic circuit with an excitation winding section, the turns of which cover all turns of the multi-turn magnetic circuit, in  (where - the number of turns of a multi-turn magnetic circuit) is times greater than the sensitivity of a known sensor, and the accuracy of measuring the speed of movement of the moving winding of the controlled object is higher due to the reduction to a minimum of the level of the alternating component of the output signal, which is not proportional to the speed of movement, which is achieved by picking up a signal proportional to the linear speed of movement of the moving measuring winding, from the load terminals to a moving measuring winding tuned to voltage resonance.
