EDAS (ENHANCED DATA ACQUSITION SYSTEM)
EDAS
DAS 8 CH
eDAS is a versatile multi-channel data logger
mostly used for structural monitoring, particularly
for the continuous control of the evolution of cracks
and any displacement of buildings and monuments.
Yet it is also suitable to record data from different
kind of sensors (including vibrating wire type) in
hydrogeological, environmental and many other
field applications.
The basic version of the logger is available with 8 or
16 channels, which can be easily increased:
• either connecting a number of units among them
via a RS485 us in order to make a larger network
with up to 255 loggers distant up to 2 km
• or expanding one basic unit with as many
additional multiplexing modules as requested
(all contained in the same box).
The system is run locally through a Pc with a USB
port or remotely via GSM / GPRS modems. It is also
possible to have a wireless version with relevant
interface accessories.
eDAS is powered by replaceable lithium batteries or
by a 12 Vcc source derived from a photovoltaic
panel or 220V mains.
The SGA control software, supplied with the unit,
allows the user to set the different acquisition
strategies, by programming the time, modes and
alarm tresholds most suitable to the specific
application, as well as to export the recorded data
in CSV format. Logged readings can be retrieved
directly on site or, if wished and implemented, from
a remote office. One more extraordinary opportunity
not requesting any interrogation of the logger to
obtain data stored in eDAS memory, is the web-
monitoring service, where measurements are
automatically transmitted to an FTP area, which
can accessed at any time from any internet
computer only through a user id and a password.
