3. Introduction to the Mag690
The Mag690 is a magnetic field sensor consisting of three fluxgate sensing elements in an
orthogonal configuration along X, Y and Z axes. This low cost, general purpose sensor is suitable
for use in the field as well as in a laboratory environment.
The sensor include fluxgate elements and associated drive electronics and will require an
external power supply and acquisition unit. Bartington Instruments offers a range of suitable
units. For further information please refer to our website or contact us at [email protected].
3.1. Vector Measurements and Conventions
The three axes of the sensor are concurrent and arranged following a ‘right-hand rule’ (Figure
1). Details of the axes position and orientation can be found in the outline drawing and on the
sensor’s label. The arrow indicates the direction for which a positive field will provide a positive
output.
