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.
