EDAS (ENHANCED DATA ACQUSITION SYSTEM) 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 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 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. * Specifications and standards subject to changes without prior notice. sistemi integrati per la diagnostica e il monitoraggio Boviars.r.L www.boviar.biz
