Anchor Strain Chain ASC-01

The fiber optic Anchor Strain Chain ASC-01 contains different strain segments in series. The sensor chain has a small diameter and is designed to become embedded inside structures (e.g. concrete, grout, plaster, …).

Each strain segment contains a single strain sensor in between two anchoring points. A relative displacement between the two anchor points is transferred into a change in the strain of the segment. The Anchor Strain Chain ASC-01 can be customized to the needs of the application i.e. the number of segments and the segment length can be chosen. The standard length of a segment ranges from 0.5 m to 5 meters. The sensor has a connector at both ends in order to make series configurations possible.

Features

Chain of strain sensors that can be directly embedded in grout or concrete.
Measurement of complex strain distributions with a single optical cable.
Detection of strain changes over base lengths up to 5 meters.
Monitoring compression as well as tension.
The displacement can be derived from the distance between the anchoring points.
