FBGuard – interrogation unit

FBGuard - interrogační jednotka

FBGuad  is FBG interrogation unit designed for measurement and data processing of measured values from FBG sensors. In this moment we can offer fast version ofFBGuard, which can be used for measurement of static or dynamic events with high accuracy in industrial conditions. FBGuard 1550 Fast unit, working in 1550 nm wavelength range, with maximum scan 11kHz in single channel version. It can be built as multi channel unit,with  2, 4 or 8 channels. How many FBG sensors can be connected to one channel is dependent on the parameter and on the measuring range, but usual amount 5-40 sensors.

FBGuard is fully autonomous unit, with inbuilt PC and hard disc inside.  Configuration of unit is possible via SSH or  web interface, unit has relays outputs, what means that in case that any value is over limit, unit can provide immediate action.


  • Up to 8 parallel optical channels (1,2,4,8)
  • Maximum scan frequency (up to 11 kHz)
  • 40 FBG sensors per channel (with the measuring range 1nm/FBG sensor)
  • Static and dynamic measurements
  • Use different types of sensors at once
  • Compact and robust design for 24/7 operation
  • Self data logging
  • Event detection (direct alarm relays, notification via email and SMS)
  • Embedded processing board with all decision functions
  • Excellent wavelength precision and accuracy
  • Ethernet or RS-485 interface (for communication)
  • User friendly web based interface
  • Large distance between the object and the measurement unit
