The embeddable strain sensor ES-01 makes use of the intrinsic strain sensitivity of the FBG in order to measure the displacement between its anchoring points. The FBG is fixed inside a ruggedized housing between two anchoring points and the entire sensor can be embedded directly inside a concrete structure. The sensor is connectorised at both ends to make series configurations possible. 

• Ruggedized housing that can be directly embedded into a concrete structure
• Direct measurement of the displacement between both anchoring points (tension, compression)
• The strain can be derived by dividing the displacement with the distance between the anchoring points.
• The FBG is an ORMOCER-coated Draw Tower Grating (DTG) which ensures high strength
• Temperature cross-sensitive: when large temperature variations are expected, a temperature sensor is recommended for compensation purposes.
