A high-precision triaxial fluxgate sensor for space applications: Layout and choice of materials

Abstract The construction of a triaxial fluxgate sensor with very high axis stability and low temperature coefficients is described. The axis orthogonalities change less than 2.1 s of are in the whole testing temperature range +20 to −10°C. The temperature coefficients for the sensitivities of the three axes are 6.7, 10.1 and 13.3 ppm K −1 , respectively. This high stability is achieved by using a newly developed ceramic, CSiC, as the supporting construction material.
