forte® 3RX Displacement DFOS Shape Sensor

Sensor Advantages

• Vertical and horizontal displacement measurements along the entire length of the sensor
• Laboratory and in situ version
• Adjustable geometry to optimise the sensitivity for a specific project
• No sensor influence on the monitored medium (negligible stiffness)
• Resistant to environmental conditions, including electromagnetic fields and lightning strikes
• Easy installation – lightweight sensor, ready to use when unrolled from the drum

Applications

• Structural health monitoring of engineering structures
• Geo- and hydro-technical engineering (e.g. slurry and retaining walls, piles, concrete columns, dams, embankments)
• Line structures: roads and bridges, tunnels, railway lines, pipelines and others
• Landslide and mining areas

Description

3RX enables to measure displacements over its entire length in three-dimensional space. It is designed to be directly embedded into the monitored structure, for example in soil or concrete, or to be installed on the surface of the existing structure. It has adjustable dimensions to fulfil the requirements of the specific project. 3RX is most applicable to monitor pipelines, landslide areas, roads, bridges, embankments and other linear structures. It provides quantitative information on displacements, movements or deflections, expressed directly in mm.

Application of DFOS shape Sensors for the structural health monitoring of real engineering structures allows for displacement measurements over entire length with a spatial resolution starting from 5 mm. The key thing is to use sensors which are accurate and reliable. Due to its negligible stiffness, Displacement Sensor allows the determination of the slip plane without impacting the soil structure which may affect the analysis and result in misinterpretation of the data.
