FBGuard – Advanced monitoring system

FBGuard - advanced monitoring system

The FBGuard 1550 FAST is a complete field proven, industrial grade FBG monitoring system designed for reliable, long term field operation (24/7) for a broad field of applications.

System is designed for high accurate static and dynamic measurements of FBG sensors, monitored at up to 16 optical channels.  This provides a cost-effective solution for many different applications.

The FBGuard is a fully autonomous system with an embedded PC and a web server running on Linux. The system configuration, sensors and alarms, frequency of measurements, data logging is possible by SSH and the web interface. An Ethernet interface allows remote connection to any standard PC through the TCP/IP protocol. Additional two USB ports are available for data exchange. The system is equipped with direct relays for immediate alarms indication. Notifications can be sent via email and SMS.

The system is equipped with a configuration and basic analysis software, platform independent.
