Abstract

The article investigated the static, dynamic and metrological characteristics of new magnetoelastic force sensors taking into account the distribution of parameters of electrical and magnetic circuits. It is shown that taking into account the distribution of circuit parameters during calculations significantly reduces the error in calculating the characteristics of magnetoelastic sensors.

Highlights

  • All over the world, research work is underway aimed at developing new power measuring elements and devices for monitoring and control systems with high sensitivity, accuracy and linearity of conversion characteristics, high reliability and stability of characteristics under extreme operating conditions

  • Magnetoelastic force sensors (MFS) are the most fully meeting the requirements of monitoring and control systems

  • It is shown that in a magnetoelastic force sensors (MFS) containing coaxially located annular magnetic circuits with sections of measuring windings and through slots made along the circumference, dividing each annular magnetic circuit into two rods, elastic conical bushings located coaxially with the annular magnetic circuits and interacting with the bases with the surfaces of the annular magnetic circuits, performing ring magnetic cores are identical and the introduction of additional, concentrically and mutually mirrored elastic conical bushings, lips Installed with the possibility of simultaneous interaction with the inner and outer surfaces of the annular magnetic cores, as well as the inclusion of the measuring windings of the annular magnetic cores with each other in series, increases the sensitivity, accuracy and linearity of the sensor conversion characteristics
