Description
This device is a special tangential field difference sensor with two AMR (Anisotropic Magneto-Resistive) bridges for field movement measurements or field comparative measurements.
Features
- Output voltage proportional to magnetic field Hy
across each chip.
- Both chips are in the same orientation and chip
centres are 3mm apart in Y direction.
- Magnetic fields vertical to the chip level Hz are not
effective.
- Disturbing fields Hx up to 30 kA/m are allowed.
- Extremely small chip distance from the top side of
package for accurate measurement
When the two peaks are the same amplitude, the magnet must be mid-way between the two chips. Therefore.
