Accessories
This section introduces the accessories currently available for the Mag639 range of sensors.
Note: All the following units are optional items. To purchase, email [e-mail]

Bartington Instruments sales team on [phone].
PSU1 and Magmeter Power Supply Units
Performance of the Mag639 is limited when used with PSU1 and Magmeter.
• Bandwidth is restricted by low-pass filters fitted within these units. Refer to the relevant data
sheet for details of filter cut-off frequencies.
• Supply voltage from PSU1 and Magmeter is nominally ±12V, limiting the available output to
less than the specified ±10V; the Mag639 will therefore only work over 90% of the specified
field strength with these instruments.
These units supply power from an internal rechargeable battery. They produce a fully isolated ±12V supply
which provides 5 hours of continuous operation. The battery can be recharged in a few hours using the
mains adaptor provided. A high pass and a low pass filter are provided in each signal path to provide a.c. or
d.c. response and to remove high frequency noise.
The Magmeter also acts as a data acquisition unit with three displays providing readings of the magnetic
field values with a maximum resolution of 0.1µT.
Full specifications of the Magmeter and PSU1 are provided in the relevant brochures with further
information in the units’ Operating Manuals.
Spectramag-6 Data Acquisition System
The Spectramag-6 six-channel, 24-bit data acquisition and spectrum analysis system is very suitable for use
with the Mag639 range of 3-axis magnetometers and any accelerometers with an ICP interface. All six-
channels are sampled simultaneously making the Spectramag-6 ideal for recording and analysing the
magnetic field and vibration data in three axes.
The unit is supplied with Windows compatible software with real-time data display and full export
capability of data and graphics. Full details of Spectramag-6 are provided in its brochure and in the
Operating Manual.
SCU1 Signal Conditioning Unit
This mains powered signal conditioning unit supplies power to a three axis sensor and allows a filter to be
configured with separate controls for the low pass and high pass sections. The filter is applied to each
output channel of the sensor. Control of gain and offset is provided for each channel independently. Full
details are provided in its brochure and Operating Manual.
