Two Axis Module

Product Code - A4051

The module comprises of a fluxgate, driver and signal processing circuitry.  The magnetometer includes additional, ‘balance' windings into which a current, derived from another magnetometer, can be injected. With the second one some 0.5m away, its output can be used to balance the earth's background field; the measuring fluxgate signal can then be highly amplified to detect minute disturbances in this field.

Using a fixed core fluxgate, the unit provides two analogue voltage (±2V) outputs for the magnetic field in two orthogonal axes. Three ranges of field level measurement are available - 50μT, 5μT and 0.5 μT (500nT) full scale. High resolution is achieved throughout the range with Autonnic's new front-end signal processing resulting in a noise level better than 1nT over the range.

APPLICATIONS

Geomagnetic surveying, gradiometry, presence and movement detection for safety and security applications.
