FBGuard IN 4
Industrial Fibre Bragg Grating Interrogation Unit
The FBGuad IN 4 is first fully industrial
FBG interrogation unit for high accuracy
static and dynamic measurements of
Fibre Bragg Grating (FBG) sensors in
field applications. It can monitor up to 4
different optical lines containing each
multiple FBG-sensors. The device is
controlled by an internal embedded PC
and is independent on external devices
and control procedures. Easy access
via web, 3 direct relay for immediate
alarms and ruggedized construction.
The system contains a broadband light source and performs spectral analysis means of a
linear CCD-array and a spectrometer platform. The input channel to be monitored can be
selected by means of an optical switch. The FBGuard monitoring unit have Ethernet
interface, which allows their remote control from any standard PC through TCP/IP. The
configuration of alarms, frequency of measurements, data logging on the internal SSD etc. is
possible via SSH and web interface as FBGuard IN 4 is designed as web server
Fibre optic interrogation unit for up to 4 optical channels
Designed for 24/7 operation
High number of sensors
Static and dynamic measurements
Embedded processing board with all decision functions
Self data logging
Excellent wavelength precision and accuracy
Direct alarm relays
Web and SSH access
Ruggedized construction
