Characteristics
  • SWS-02 is improved sensor, developed to replace our SWS-01 sensor
  • Upgraded and more compact version of SWS-01 sensor.
  • SWS-02 short gauge spot-weldable strain sensor measures strain changes in μɛ or extensions (elongation) in μm.
  • With integrated temperature compensation.
  • SWS-02 can be connected in series configuration.
Applications
  • Strain changes detection.
  • Steel deformations, etc…
  • Can be mounted on different surfaces including pipelines, walls, etc.
