Strain Sensor EFO

The EFO is a fi ber optic strain sensor especially designed to be embedded in concrete, ideal for composite material engineering research and civilengineering applications such as monitoring stresses in structural members of buildings, bridges, tunnel linings and supports during and after construction.

Specifi cations:
1) Strain range: ±1000με, ±1500με, ±2000με, ±3000με
2) Resolution: 0.01% of full scale
3) Transverse sensitivity: <0.1% of full scale
4) Connector type: ST connector
5) Operating temperature: - 40°C to 85°C (- 40°F to 185°F)

Features:
1) Immune to EMI/RFI/Lightning
2) Intrinsically safe; Static/dynamic response
3) High sensitivity and resolution of 0.01% of full scale
4) Signal transmitted over long distances
5) No interference due to fiber bending
6) Absolute measurements in engineering units

Applications:
Dams; Bridges; Tunnel linings
Nuclear power plants; Buildings
High performance and reactive powder concrete
Corrosive environments
High EMI/RFI environments
