Abstract :
Based on the finding that the temperature dependence of fluxgate sensors is proportional to the measured field, a temperature compensation circuit is described using the copper resistance of the fluxgate secondary winding as the thermosensitive part of a bridge. The bridge voltage is derived from the magnetometer output so the compensation is only active in high fields.
