Fiber Optic Strain

FBG Strain Sensor EST-01

Embedded FBG temperature compensation strain sensor EST-01 is mainly used for internal strain measurement of concrete, reinforced concrete or plastic materials such as foundations, pile foundations, bridges, tunnels, linings, etc, so as to facilitate long-term observation of structural stress and strain changes and state analysis. The sensor has a built-in temperature compensated FBG, adopts a unique elastic beam structure, and has high measurement resolution and measurement accuracy. The signal can be transmitted over long distances through optical fibers.

Features of EST-01

  • High Resolution

  • Immune to EMI/RFI/Lightning

  • Robust and High Reliability

  • Monitoring of Compression As Well As Tension Possible

  • Watertight and Capable of Service in Harsh Environment

  • Long-term Stability

Application of EST-01

  • Bridges

  • Tunnel Linings

  • Nuclear Power Plants

  • Buildings

  • High Performance and Reactive Powder Concrete

  • Corrosive Environment
