Description

The 3D Magnetic Sensor Calibrator is an innovative device for calibrating magnetic field with high resolution.
This calibration sensor device measures all three axes of the magnetic field, by performing a scan over the full unit sphere, independent of its orientation relative to the magnetic field. The calibration device rotates continuously around two orthogonal axes and the full range of polar and azimuthal angles is covered by a respective rotation. The parts of the device to be rotated are made very compact to fit in between pole pieces of a magnet.
