Distributed Sensing System: Model DSS 4300

Source: Luna Technologies, a Division of Luna Innovations Incorporated

Luna Technologies’ Distributed Sensing System™ (DSS) 4300 is a fiber optic sensing tool for making distributed measurements of temperature and strain. The DSS uses swept-wavelength interferometry to simultaneously interrogate thousands of sensors integrated in a single fiber. These sensors consist of discrete Fiber Bragg Grating (FBG) point sensors which can each reflect the same nominal wavelength. As such, the sensors can be fabricated on the draw tower, eliminating the need for individual grating fabrication. The Distributed Sensing System combined with Luna’s sensing fiber provides a tool for distributed sensing with up to 1 cm spatial resolution along the length of the fiber.

  • Highly distributed fiber sensing for strain and temperature
  • Centimeter resolution up to 70 meters
  • +/- 0.1°C , +/- 1µ strain resolution at 1 cm
  • High speed – 5 second acquisition times at high resolution
  • High temperature capabilities – up to 300°C


Structural monitoring for naval, aerospace and civil structures:

  • Conformal deformation and shape sensing
  • Composite damage assessment
  • Bonded joint integrity monitoring

Temperature profile monitoring in extreme environments:

  • Cryogenic fuel tanks
  • Fuel cells
  • Concrete cure temperature monitoring in large structures
  • Industrial chemical process monitoring
  • High temperature capabilities - up to 300°C

Pipeline shift and leak detection
Electrical power line sag and temperature monitoring
Health monitoring of wind turbine blades and power generators
And more...
