Description
The mountable strain sensor measures the deformation between its anchoring points. The fibre optic sensor is fixed inside a ruggedized housing that is connected to the anchors using nuts. The anchors are bolted in concrete or welded to metal constructions. The nuts are also used to apply pre-tension on the sensor to monitor compression and elongation. The distance between both the anchoring points can be chosen between 70 and 100 mm. The sensor has fibre optic cables at both ends in order to make series configurations possible.
Features
- Detection of displacements and strains with sub-micrometer precision
- Fibre with high breaking strength: ≥ 5% strain
- Monitoring of compression and tension
- Sensors can be placed in series and hereby reducing the cabling to a minimum
- Optional temperature compensation via optical fibre temperature sensor in series
- Watertight and ruggedized housing, applicable in harsh environments
