The strain of the tensioner may be detected by an optical device having a Fiber Bragg Grating (FBG) that is attached to the tensioner.

The calculated load may be stored and analyzed, along with previously-stored values for the load, to determine the condition of the tensioner system, and whether the tensioner system requires maintenance.
