Characteristics
  • SB-01 is a directly embeddable strain sensor possible to be implemented inside an existing rebar cage. The sensor can be tied or welded to the existing structure.
  • SB-01 offers measuring of strain changes in µɛ within the length of the sensor.
  • SB-01 can be manufactured for different rebar sizes and lengths. Individual sensors can be connected in a series configuration.
  • Directly embeddable strain sensor without requiring any further supportive elements.
  • No pre-strain adjustment is required during installation and setup.
Applications
  • Strain measurement inside concrete structures.
  • Combined with the TP-03 temperature sensor the SB-01 offers temperature compensated strain monitoring.
