3. Introduction
These compact, high performance sensors with integral electronics provide measurements
of static and alternating magnetic fields in three axes. The sensors, also described as
magnetometers, convert magnetic flux density, measured in three axes, into a bipolar analogue
voltage. Analogue output voltages Vx, Vy and Vz vary linearly with magnetic flux density.
The Mag-13 series are an evolution of the Mag-03 range of sensors and feature a number of
improvements. These include improved orthogonality error of the sensing coils, and an inbuilt test
coil and temperature sensor. There have also been other refinements in the design.
The analogue output is positive for conventional flux direction, South to North, in the direction of the
arrow shown on the label for each axis; i.e. the maximum positive output will be obtained from any axis
