SOFO VII MuST Reading Unit Datasheet

TECHNICAL DESCRIPTION The SOFO VII reading unit allows to measure 4 or 8 channels. On each channel it is possible to connect up to 5 SOFO sensors (external 1x5 splitter needed) and up to 25 MuST FBG sensors (depending on sensor type, see sensor datasheets for details). The unit contains a field PC that provides data logging and remote interfacing functionalities. The main features of SOFO VII are: flexibility in the choice of the options allowing the customer to configure a system tailored to his needs in terms of sensing technology, data logging capability, communication and temperature range. The SOFO VII has been designed for surface installation and for specific project requirements. The housing (IP 66, housing and door: e-coat primer, powder painted, RAL 7032 pebble grey) grants protection from water, rodents, accidental crashes and a key lock grants protection against vandalism. Options ? 8 channels option ? SOFO sensor 1x5 splitters ? Heating and thermal isolation for use in rigid climates FEATURES ? Permanent instrumentation ? Compatible with SOFO sensors ? Compatible with all MuST FBG sensors ? Mix-and-match SOFO and MuST technologies in a single project ? High resolution and precision ? No calibration required ? Integrated PC with SDB measurement engine software ? Compact size and modular design ? Automatic and remote control ? Ethernet interface for easy networking GENERAL DESCRIPTION The SOFO VII reading unit is a universal reading unit able to measure both SOFO (Interferometric) and MuST (Fiber Bragg Grating) sensors. The system is designed for static, long-term measurements. Each channel can be software configured for one of the two technologies. The SOFO VII is integrated in a compact steel housing designed for permanent installation in any structure that requires continuous monitoring. 10.2011 SOFO VII SOFO / MUST UNIVERSAL READING UNIT SMARTEC SA a Nova Metrix company PRELIMINA SPECIFICATIONS AC power supply 230 V 50 Hz / 110 V 60 Hz Auto detect External connections Ethernet connection, 8 optical ports, power supply, display and screen (optional) Data logger capacity Typical 5 year of data with measurements every 1h.
