摘要
A fluxgate magnetometer having wide temperature range accuracy, without adding temperature compensating components, is obtained by: (1) a fluxgate adjusted by aligning a permeable magnetic tape core relative to the secondary winding of the fluxgate so as to substantially equalize each of the pulses induced in the secondary winding by the transition from core saturation to unsaturation in both directions, and (2) increasing the fluxgate magnetometer primary drive current above what is normally considered saturation current to reduce sensitivity of the output to temperature and primary drive changes.
