  • FiberSensing BraggSCOPE measurement unit for FBG sensors combines high-power broadband optical source with proven thinfilm optical filtering technology in an intelligent approach to perform dynamic measurement of the Bragg wavelength.

    BraggSCOPE
    The proprietary BraggSCOPE technology is based on wellestablished integrated add/drop WDM components, which enable a cost-effective filtering solution for Bragg wavelength measurement within predefined bands. Up to four sensors can be connected in series, which in combination with embedded optical multiplexing makes this measurement unit suitable for medium scale dynamic sensing networks.

    Configuring sensors is easy and straightforward. Each FiberSensing sensor is provided with a configuration file, allowing its characteristics to be automatically inserted, so measurements can start immediately after plugging the sensor.

    PORTABILITY
    Autonomous battery operation and high level of integration offer true portability over extended time. The Portable unit is supplied with a rugged carrying case optimized for field operation.

    DATALOGGER
    The intuitive and easy-to-use touchscreen graphical user interface provides the user with datalogging functions for automated sampling, archiving and transmission. A highperformance local database manages both multiple sensor network configurations and large datasets. Acquired data can also be exported to analysis tools through Excel™ compatible files.
