Bartington Data Acquisition Module, Mag-03DAM
 |
| |
 The
Mag-03DAM is a 6 channel, 24 bit resolution module
for the collection of data from any two Mag-03 sensors
or a Grad-03-12 gradiometer. If used in conjunction with
one sensor only, other inputs may be used to record analog
signals from other sources. All inputs are protected against
voltage surges.
The unit incorporates a battery backed power supply for
the sensors. Power is provided via a mains adapter and
data is transmitted to the user's computer via an optically
isolated RS-232 serial interface. The analog signals from
the sensors are available for external use. The data acquisition
module can be located up to several hundred meters away
from the sensors. Software is provided for storing one
minute average or five second values to disk.
