SYSMALOG
SUPPORTED INVESTIGATION
Passive seismic acquisition
Seismological studies
Territorial seismic monitoring
Seismic acquisition device of standalone
type, particularly suitable for
seismologic and monitoring studies of
local seismic events.
The unit has been designed to record
and automatically save each seismic
event on internal hard disk, according
to the set methods. It can be completely
managed with PC, through LAN
network interface. The recovery of the
data stored in the unit can take place
through USB connection or through
integrated GSM/GPRS module.
The high technological content and
high level of flexibility of Sysmalog offer
utmost accuracy in acquiring data,
combined to the extreme simplicity
and promptness in configuration operations.
Sysmalog is an acquisition
unit that can be managed remotely,
equipped with high resolution (24 bit)
acquisition card, with specific sampler
for each inlet channel. The particular
architecture of the software allows to
install almost any software onboard
the instrumentation, for specific seismology
and seismic monitoring studies
or studies on the dynamics of the
structures, therefore this device is
particularly suitable for all applications
that require utmost adaptability
of the instrumentation to the specific
needs of the survey that must be
carried out. MAE suggests the use of
SEISLOG software, developed by the
University of Bergen. Bergen, Norway,
