Description
The DiTeSt SMARTprofile combined strain and temperature sensors are designed for distributed deformation (average strain) and temperature monitoring over long distances, using BOTDR / BOTDA (Brillouin scattering) technologies.
The DiTeSt SMARTprofile sensor consists of two bonded and two free single mode optical fibers embedded in a polyethylene thermoplastic profile. The bonded fibers are used for strain monitoring, while the free fibers are used for temperature measurements (quantitative if sensor deformation <0.2%, qualitative if sensor deformation >0.2%) and to compensate temperature effects on the bonded fibers. For redundancy, two fibers are included for both strain and temperature monitoring. The profile itself provides good mechanical, chemical and temperature resistance. The small size of the profile makes the sensor easy to transport and install by embedding in concrete or mortars, gluing or clamping. The SMARTProfile sensor is designed for use in environmental conditions typically found in civil, geotechnical and oil & gas applications. However, this sensor cannot be used in extreme temperature environments, nor in environments with aggressive chemicals. It is not recommended for installation under permanent UV radiation (e.g. sunshine) without an additional cover or aluminum tape protection.
The SMARTprofile sensing cable is delivered on spools with all the necessary accessories such termination and connectors (E2000, FC-PC or other).
