Two Tone Excitation for Fundamental Mode Orthogonal Fluxgate Gradiometer
Original language description
This proceedings paper presents a novel method of excitation for fundamental mode orthogonal axial gradiometer based on single core magnetic microwire. The standard excitation of DC biased fundamental mode fluxgate is modifided to utilize two-tone sine wave excitation and two pick-up coils tuned to resonance at different frequencies. This method brings new ways for individual adjustment of gradiometer pick-up coil sensitivities, lowers the effect of spatial cross-sensitivity due to coils LC circuit mutual coupling and adds the possibility to use the two pick-up coils in series with a single preamplifier while keeping the axial gradiometer output, which further simplifies the design of the electronics.
