DISTRIBUTED SENSING SYSTEM
(Model DSS 4300)
The Luna DSS 4300 is ideal for sensing
applications that require high resolution, broad
strain or temperature range and rugged and
cost-effective fiber sensors.
MEASUREMENT PERFORMANCE HIGHLIGHTS
• ±1 µStrain resolution
• ±0.1 c resolution
• 1 cm spatial resolution up to 70 meters
• Measure thousands of sensors in a single fiber
APPLICATIONS
• Structural health monitoring for naval, aerospace and civil
structures
• Conformal deformation and shape sensing
• Composite damage assessment
• Temperature profile characterization
• Industrial chemical process monitoring
Luna’s
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 on 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.
Luna’s revolutionary sensing technique uses fiber
sensors with drastically reduced cost compared to
competitive solutions, minimizing both the time and cost
to market for your sensing application.
