4. Installing the Mag690
4.1. Positioning the Magnetometer (Environmental Recommendations)
It is recommended to keep the sensor away from strong sources of AC and/or DC magnetic fields
which may saturate the sensor. Due consideration should also be given in the position of the
sensor in respect of ferromagnetic objects (application dependent).
Note:
Avoid placing the sensor in contact with electrically conductive material in order to
prevent the generation of eddy currents. These may create additional offsets.
4.2. Mounting Recommendations
Each magnetometer has a set of mounting holes to allow attachment to a stable base or fixture.
Refer to the mechanical drawings on the product page for details.
The sensor can also be mounted on the Bartington Instruments Mag-TA Universal Tripod
Adaptor.
4.3. Connection Recommendations
4.2.1. Connector Pin Allocation
Connector pin-out or cable wiring schedule for each sensor variant can be found on the outline
drawing available on the website product page.
Caution:
When fitting your choice of connector to the Mag690FL, refer to the product
brochure for wire gauge and carefully follow any instructions and recommendations issued
by the connector manufacturer.
Do not use a Mag648 cable (Black Binder connector) to connect a Mag690 (Blue Binder
connector) as this can damage the device. Always match the colours of the Binder
connectors; Blue to Blue, Black to Black.
4.2.2. Interface
Diodes protect against reverse connection of power voltages of up to 40V. X, Y and Z outputs are
protected against short circuit to 0V.
Caution:
Short circuits from output to either power rail may result in permanent damage to
the sensor. Limit the power supply current to 100mA to minimise risk of damage caused by
incorrect connection.
The low impedance of the three analogue outputs enables the unit to be operated over long
cables and interfaced to high impedance data acquisition systems.
