measurement axes are designated X, Y and Z in the Cartesian co-ordinate system, when viewed
from the top or non-connector end of the sensor.
In designing the Mag-03 series, the policy has been to provide a high performance sensor having
a flat amplitude response and a small, predictable phase lag over a wide bandwidth. The analogue
outputs may require external filters if not used with a Bartington Instruments data acquisition unit
to achieve the noise specification of the sensor . See
Section 13 on Signal Processing
.
4. General Description
This section describes the features common to the Mag-03 range of sensors. Exceptions are
described in the product brochure.
Three fluxgate sensing elements are mounted orthogonally at one end of an enclosure, which also
contains the electronic circuitry. The connector is mounted at the opposite end of the enclosure.
The position and direction of each sensing element is shown on the outside of the sensor, together
with the product code, measuring range and serial number. The sensor elements are precisely
aligned along the centre lines of the package, directly beneath the diagram on the label.
Details of the enclosures, mounting, connector dimensions, connector pin allocation and the
position of the sensing elements relative to the enclosure are given in outline drawings on the
Mag-03 product page.
The sensors provide three high precision analogue outputs, proportional to the magnetic field
along each axis. The relationship between the magnetic field and the analogue output is extremely
linear.
The low output impedance of the sensor ensures it can be operated over long cables and permits
it to be interfaced to high impedance data acquisition systems. The zero field offset error, scale
factor, orthogonality and frequency response are individually calibrated.
5. Enclosures
A variety of enclosures and measuring ranges are available. A full list of sensors with
specifications is provided in the product brochure.
Note:
Several Mag-03 enclosures are awarded IP (Ingress Protection) ratings as determined
by the IEC 60529 standard. These ratings are shown in the product brochure. Users are
advised to consult this standard, available from the IEC website at
www.iec.ch
, for the
precise definitions and limitations of each IP rating.
Caution:
Using your sensor in an environment that exceeds its rating may result in the need
for repair at the customer’s expense.
