AB001-00E GMR Gradient Sensors (Gradiometers) offer unparalleled magnetic gradient
sensing. Two pairs of unshielded GMR bridge resistors provide directional sensing
of small gradients over a wide range of magnetic field strength. The devices
are sensitive only to gradients, and have low sensitivity to constant magnetic
noise.

ABH001-00E GMR Gradient Sensors (Gradiometers) offer unparalleled magnetic gradient sensing. Two pairs of unshielded GMR bridge resistors provide directional sensing of small gradients over a wide range of magnetic field strength. The devices are sensitive only to gradients with low sensitivity to constant external magnetic noise. This allows these sensors to operate in high noise environments, such as near electric motors or high-current wires.
