SENSORS FOR VECTOR MAGNETOMETERS

Jan Včelák – Petr Kašpar

   The advantages and disadvantages of using several types of magnetic sensors to design vector magnetometer will be discussed in this paper. Three developed versions of vector magnetometers with AMRs (anisotropic magnetoresistors), ring-core fluxgate (Aschenbrenner-Goubau type) and PCB fluxgate sensors will be presented as well as the calibration technique, achieved accuracy and performance of the magnetometer during calculation of scalar magnetic field. The individual requirements for power consumption are also discussed in this paper.

Keywords: magnetometers, vector, magnetic sensors
