Abstract

This article analyzes the transducers of mechanical quantities developed by various authors, invariant to destabilizing factors and ways to reduce the sources of errors affecting the main characteristics. At the same time, special attention is paid to the causes of various errors associated with the properties of the magnetic material, such as magneto elastic hysteresis and the nonlinearity of the transformation function. Additional errors caused by temperature changes and their studies have shown the possibility of reducing the temperature error by selecting the material of the magnetic circuit and choosing the optimal power supply modes. Fluctuations in the frequency and amplitude of the supply voltage are factors that significantly affect the sensitivity, while causing additional error, and the use of the classic Royer multivibrator scheme increases sensitivity.
