Method and Apparatus for a Structural Monitoring Device Adapted To Be Locatable Within a Tubular Structure

摘要

A structural monitoring device adapted to be locatable within a tubular structure, the monitoring device comprises a plurality of supporting arms for supporting a plurality of fibre optic strain sensors; whereby each said supporting arm is arranged to support each said fibre optic strain sensor adjacent to an inner surface of the circumference of a monitored tubular structure to provide information indicative of strain sensed along a first axis and information indicative of strain sensed along a second axis.
