Solutions Oil & Gas, Energy, Mining Pipeline Strain Monitoring
Fibre Bragg Gratings along single-mode fibres are packaged into discrete weldable strain gauges. FBG gauges of differing nominal frequencies and types are joined in series to allow for 10’s of gauges to be monitored on 1 channel which creates a “Station.” An optical interrogator completes sensor identification, interrogation and temperature compensation of distances of up to a few kilometres.
