fTB 5020

Fiber-optic sensing for distributed strain and temperature monitoring

Uninterrupted monitoring is essential to manage risks and maintenance of large structures. Where kilometers of concrete, steel, or soil require monitoring for early signs of failure, distributed fiber optic sensing is a powerful and highly efficient tool.

With industry-leading accuracy, fibrisTerre’s unique patented Brillouin Optical Frequency Domain Analysis and Reflectometry (BOFDA and BOFDR) technology answers the demand for reliable, continuous, and long-term monitoring of civil and transport infrastructure.

Distributed strain and temperature sensing system (DTSS, DSTS)

Key features:

Loop configuration (BOFDA)

  • Spatial resolution: < 0.2 m
  • Measurement length > 80 km
  • Repeatability: < 0.1°C, 2 μm/m
fibrisTerre 5020 interrogator

Single-ended configuration (BOFDR)

  • Spatial resolution: 1.5 m
  • Measurement length: > 25 km
  • Repeatability: < 1°C, 20 μm/m

Measurement and performance parameters such as distance range, spatial resolution, measurement accuracy and acquisition time are interdependent. For available length/resolution settings, see instrument options below, the product brochure and of course, you may contact us.

fTView: Control – Display – Analyze

The fTB 5020 is controlled by a remote or local PC or workstation via Ethernet. fTView, fibrisTerre’s powerful software, enables the configuration, operation, display, and management of measurements.

  • Easy measurement setup
  • Automatic long-term monitoring
  • Automatic data management and export
  • Unique, powerful signal engine
  • Full access to raw data for detailed analysis, e.g., bad connector identification
  • API available for remote access as well as SNMP and Modbus for interfacing with SCADA systems.
