Detailed Product Description

The SBS ( Stimulated Brillouin Scattering) Strain Cable makes use of the inherent strain sensitivity of the Fibre. One single fibre can replace thousands of point sensors thanks to the distributed sensing concept. This concept refers to the use of a single optical fibre as a linear uninterrupted sensor providing multiple sensing points distributed over the whole fibre length.

The fibre is inserted into a stainless steel capillary with a diameter of 1,5 mm . The fibre is prestrained inside the capillary, which makes it possible to measure both extension and compression.

Features

The SBS Temperature sensor can measure distributed strain with a resolution of 2 µ e and an accuracy of 20 µ e . The sensor is also sensitive to temperature changes, 1°C corresponds to 20µ e. In order to compensate for these influences, the strain cable should be applied in combination with the SBS temperature cable.

Applications

Strain measurement of large structures such as pipelines, off-shore platforms, oil wells, dams, dykes, bridges, buildings, geostructures, tunnels, cables,
