Characteristics
  • SSR-01 is a spot-weldable strain rosette consisting of three strain gauges available in a delta configuration that features a 60° angle oriented configuration.
  • SSR-01 is installed using spot-welding or direct gluing to the surface.
  • Integrated temperature compensation.
  • [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.
Applications
  • Strain changes detection
  • Steel deformations, etc…
  • Can be mounted on different surfaces including pipelines, walls, etc.

Quality Statement SSR-01 sensor is compliant with IEC 61757-1-1:2020, IEC 61757:2018, and IEC 61757-2-1:2021 All sensors are 100% tested and calibrated at SYLEX. The sensor is manufactured according to ISO 9001:2015 and ISO 14001:2015.

Notes:

  • 1) Accuracy is established for each sensor under laboratory conditions and it includes hysteresis, non-linearity, and repeatability of the sensor. The guaranteed value is determined based on the largest absolute error found in this sample. The typical value is determined based on the average absolute error found in this sample.
  • 2) Precision is established on a batch basis and it includes hysteresis, non-linearity, repeatability, and reproducibility of the sensor. The guaranteed value is determined based on the largest absolute error found in this sample. The typical value is determined based on the average absolute error found in this sample.
  • 3) FS: full-scale calibration range.
  • 4) Optional feature. The temperature sensor will be embedded into the rosette body.
  • 5) Thickness with the primary protective layer. Further dimensions details see the product drawing
  • 6) Cable length is extendable on request
  • 7) Other connector types available on request
