Abstract:
This paper presents results of investigation on influence of stress from the external forces on the sensitivity of the fluxgate sensor with 80% Ni-Permalloy P-80M ring core. Stress was applied in two directions: in the direction of diameter of the ring or in perpendicular direction to the magnetising field in the ring core. The influence of mechanical stress from the external forces on the magnetic properties of this ring core was measured. Then results of this testing were used in computer simulation of the influence of stress on the output signal of the fluxgate. The results confirmed, that stress sensitivity of the fluxgate sensor’s core material must be taken into consideration during the development of such device.
