Investigation of the accuracy characteristics of magnetoelastic transducers by the method of power polynomials

This paper shows the results of a study of the accuracy characteristics, based on the obtained dependence of the specific magnetic resistance on magnetic induction by the method of power polynomials. A comparative assessment of the existing methods of approximation by power polynomials is made and their advantages and disadvantages are revealed. The approximation proposed by the author most accurately reflects the nature of the change in the magnetization curve. Convergence of experimental and calculated curves is established.
