Mag-03®
Three-Axis
Magnetic Field Sensors
These compact, high performance fluxgate sensors
with integral electronics provide precision measurements of static and alternating magnetic fields in three
axes. They are available in a variety of enclosures.
Powered from any ±12V supply, outputs are in the form
of three analogue voltages from 0 to ±10V, proportional
to Bx, By and Bz.
The sensors have a very wide range of applications in
physics, bioelectromagnetics and geophysical exploration
A range of power supply and data acquisition units are
available.

Calibration Units
These units provide a fast and convenient facility to test the functionality of a
Mag‑03 sensor. They consist of a battery powered single axis Helmholtz coil
generating an alternating magnetic field, with guides to align each of the sensor
axes in turn.
Note that these units are not intended as a full calibration facility. It is recommended that sensors are returned to Bartington Instruments for full calibration.

Sensors have threaded holes tapped in
the base which is also the datum face.
The sensors can be mounted on any flat,
non-magnetic surface, including the top
of the mounting bracket, using the two
brass screws supplied. A thin gasket
or a suitable sealant should be used to
seal the base of the units against water
penetration.
