The SMARTprofile strain sensors are transducers that transform a strain variation into a change in reflected wavelength of a FBG encapsulated into a surface mountable patch. These sensors are compatible with SMARTEC MuST Reading Units. Small cross-section (width ~8 mm; thickness ~3 mm) and composite packaging properties make it ideal for its application in harsh on-site conditions. It features high mechanical, chemical and temperature resistance.
It can be effectively used in the following applications:

• Structural monitoring of naval structures
• Sub-sea applications; e.g. monitoring of shallow and deep-water risers, off-shore platforms, and other oil & gas structures
• Industrial and military structures etc.

The SMARTprofile can be simply bonded or clamped to any kind of surface such as steel, composite, concrete, etc.

The SMARTprofile sensor is composed of an active and a passive zone. The active zone contains the composite sensing profile with embedded one or two Fiber Bragg Gratings (the second for temperature measurement and compensation). The metallic tube containing the optional temperature sensing FBG is also embedded in the same profile. The active zone serves as a measurement basis of the sensor. The passive zone is composed of the interconnection cable and a connector. Up to 4 such sensors can be chained to form a single sensing array. The temperature sensor can only be installed in the terminal sensor of the chain. Standard E-2000 connectors with a built in protective cover are used to connect the sensor with the reading unit or extension cables.
