Autrefois, nous étions perçus seulement comme fournisseurs de services, vendeurs de produits et employeurs. Aujourd'hui, nous partageons une grande partie de la responsabilité pour la qualité de la vie. Les entreprises gagnantes prendront en compte cette responsabilité croissante naturellement, sinon toujours immédiatement.

K-STR - Strain Sensors

The K-STR strain sensors are based on the principle of Bragg grating. Their specific design makes them preferentially sensitive to mechanical stresses to which they are submitted (variations of pressure, tension, torsion...). Their single string configuration allows the integration of several of these sensors, which simplifies the deployment of this type of cable for monitoring, in real time, structural deformations, vibrations recorded in the ground, on walls, quantifying elongations.


  • Standard sensitivity : ~ 1.5pm/µm

  • Compatible with an integration of several sensors (contact us)

  • 4 fibers queryable with a single query system as standard
    (more upon request)

  • High reactivity (instant response time)

  • Measurement distance (standard) : 0 - 50 km

  • High temperature sensitivity < 0.5°C
