RTS250+ DFOS System

Sensuron's fastest distributed fiber optic sensing interrogator, producing real-time distributed strain and temperature profiles at acquisition rates up to 200 Hz. Supplied as a compact, ruggedized, portable unit.

RTS250+ DFOS System

Technical overview

The RTS250+ is a distributed fiber optic sensing (DFOS) interrogator that reads thousands of equally spaced sensing points along a standard optical fibre rather than at discrete points. It operates in two modes: eight simultaneously monitored fibres at 100 Hz, or four fibres at 200 Hz, with over 2,000 sensors per fibre. Spatial resolution is software-selectable down to 1.6 mm as a custom order, with 6.3 mm the highest stock resolution, and maximum sensing length is offered at either 52 m or 104 m. Sensuron states the platform also derives 2D shape, deflection, pressure, stiffness (bending and torsion), liquid level and operational load in addition to strain and temperature.

Features

  • Acquisition rate up to 200 Hz
  • Dense data acquisition: up to eight fibres simultaneously in 100 Hz mode, over 2,000 sensors per fibre
  • Scalable sensing range: 52 m or 104 m maximum sensing length
  • Software-selectable spatial resolution down to 1.6 mm (custom order option)
  • Structural deflection and 2D shape measurement beyond strain and temperature
  • Immune to electromagnetic interference (EMI/RFI) and radiation
  • Ruggedized design for harsh industrial and outdoor conditions
  • Multiple dedicated high-speed channels
  • Network API for integration with external measurement systems and automation platforms
  • Compact and portable: described as about the size of a loaf of bread, 13 lb
  • LabVIEW and MATLAB example applications and stubs
  • IRIG-106 Chapter 10 data stream converter (Telspan)
  • Interface with Moog load control systems for structural testing
  • Pacific Instruments Series 6000 signal conditioning DAQ interface
