6. Compatible Power Supply and Data Acquisition Units
A number of Bartington Instruments products will work with the Mag-03 as power supply and/
or data acquisition units. These are listed in the product brochure, and can be found at
www.
bartington.com/data-acquisition-and-conditioning-units.html
.
For further information on power supplies see
Section 11.3: Power Supplies
.
For information on using your own power supply or data acquisition unit see AN0042: ‘Connecting
your own Power Supply to a Bartington Magnetic Field Sensor’, available from Bartington
Instruments.
7. Cables and Connectors
7.1. Cables
Cables are available to connect the range of Mag-03 sensors to the range of suitable Bartington
Instruments power supply and data acquisition units. Specifications for each of the cables are
given in the product brochure.
Note:
Cables must be ordered separately.
Note:
Customers manufacturing their own cables must ensure the cables are shielded to
prevent them picking up EM (electromagnetic) interference.
Note:
The connecting cable to the sensor should be an eight-core screened cable. Two cores
will be used for positive and negative power supply lines, three cores for output signals, one
core for signal common and one for power supply ground. The screen should be connected
to supply ground at the supply end only. The capacitance between cores should be less than
200pF per metre. A cable with individually shielded cores should be considered for long
cable applications.
Note:
The length of the cable is limited by the voltage drop in the power supply lines and the
capacitance between the cores. For this reason it is recommended that the cable is limited
to a maximum length of 600 metres.
7.2. Mating Connectors
All sensors, except for the Mag-03MSS, are supplied with a non-magnetic mating connector if no
cable for connection to a power supply or data acquisition module is purchased.
Note:
The Mag-03MSS mating connector must be purchased separately.
