  • SWA-00 is a spot-weldable strain sensor with a single strain FBG attached to a flexible body made from a 0,2mm thin metal sheet simply adaptable to any surface curvature.
  • [Optional] Integrated temperature compensation.
  • One-body design for both strain and temperature measurement.
  • Surface-mountable using spot-welding or direct gluing to the surface.
  • No need for adjusting pre-strain during installation.
  • Strain changes detection
  • Steel deformations, etc…
  • Can be mounted on different surfaces including pipelines, walls, etc.
  • Any curved objects.
