The magnetic field sensor and the electric current sensor which measure the magnetic field direction inside plane surface

摘要

As for the magnetic field sensor in order to measure the magnetic field direction inside plane surface, two detection structures which can operate as a rotary hall device (1A; 1B) it includes. Two hall devices to opposite direction turn with discrete step. Can this kind of magnetic field sensor, use in the conductor (15) as the electric current sensor in order to measure the primary current which flows. Selective figure Figure 4
