Abstract:
This paper presents results of investigation of the stress sensitivity of the fluxgate sensor with amorphous alloy (CoFe)89(MnMoSiB)11 (Vitrovac 6150F) ring core. Stress was applied in two directions: perpendicularly to the flux density in the ring core or in the direction of diameter of the ring. The influence of mechanical stress from the external forces on magnetic properties of this ring core was measured. Then results of this testing were used in computer simulation of the influence of the stress on the output signal of the fluxgate sensor.
