Senowell Uptech UTS-BB1000 Distributed Temperature & Strain Monitoring System

Distributed Temperature & Strain Monitoring

The Senowell Uptech UTS-BB1000 is a high-performance Distributed Fiber Optic Sensing (DFOS) system designed for temperature and strain measurement along the length of a fiber optic cable.

The system provides distributed temperature and strain monitoring for long-distance infrastructure, allowing engineers to obtain spatially resolved measurements across extensive assets rather than relying solely on conventional point sensors.

The UTS-BB1000 incorporates noise-reduction techniques designed to support high-precision measurements over long monitoring distances while maintaining relatively short measurement times. This makes the system suitable for applications where engineers need detailed information about structural and thermal behaviour across large areas.

Long-Distance Distributed Fiber Optic Monitoring

The UTS-BB1000 is designed for monitoring applications where temperature and strain need to be measured over significant distances.

The system's multichannel architecture allows multiple fiber optic cables to be monitored. The manufacturer states that the system can support monitoring distances of up to 160 km in linear infrastructure and up to 960 km when all channels are used. The stated individual measurement range is up to 80 km.

This makes the UTS-BB1000 particularly relevant for large-scale infrastructure such as pipelines, power cables, railways, civil structures, geotechnical assets and industrial installations.

High-Resolution Temperature & Strain Measurement

The UTS-BB1000 provides distributed measurements along the sensing fiber with a stated 20 cm spatial resolution.

The system's published precision is 0.1 °C for temperature and 2 µε for strain, with a stated measurement time of approximately 3 minutes.

This combination of spatial resolution, measurement precision and long-distance coverage enables engineers to identify where changes in temperature or deformation are occurring along the monitored asset.

Distributed Sensing Without Conventional Point Sensors

Traditional monitoring systems often rely on sensors installed at predefined locations.

Distributed fiber optic sensing takes a different approach: the fiber itself becomes the sensing medium.

This allows engineers to obtain temperature and strain information continuously along the monitored fiber, helping identify changes that may occur between conventional sensor locations.

For large infrastructure assets, this can significantly increase the spatial coverage of a monitoring system.

Structural Health Monitoring

The UTS-BB1000 can be used as part of a Structural Health Monitoring (SHM) system to observe changes in structural behaviour over time.

Distributed strain measurements can provide engineers with information about deformation and structural response across bridges, tunnels, dams, transportation infrastructure and other civil assets.

The technology is also applicable to geotechnical monitoring, where distributed fiber optic sensing can be used to monitor deformation and ground movement across extended areas.

Pipeline & Asset Integrity Monitoring

For pipelines, distributed temperature and strain measurements can provide information about conditions developing along the pipeline route.

Distributed sensing can complement other technologies such as Distributed Acoustic Sensing (DAS) for applications involving pipeline integrity, leak detection, third-party intrusion and ground movement.

Power Cable Monitoring

Distributed fiber optic sensing can also be deployed alongside power infrastructure to provide information about temperature and strain.

Temperature monitoring can support assessment of cable operating conditions, while distributed measurements can provide additional information about the physical behaviour of the monitored cable route.

Control Unit & Monitoring Software

The UTS-BB1000 solution can be integrated with the UTS-CU1000 Control Unit, which operates the UTS-nerVision software environment.

The CU1000 provides configuration, management and visualization capabilities for compatible 1000-series distributed fiber optic sensing equipment. It can also communicate with central servers and SCADA systems, enabling remote monitoring and integration with wider infrastructure management systems.

Designed for Industrial Deployment

The monitoring solution is available in rack-mounted and wall-mounted configurations, allowing it to be integrated into industrial monitoring environments and infrastructure control facilities.
