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

摘要

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 arc in the whole testing temperature range + 20 to - 10℃. 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. # 1997 Elsevier Science S.A.
