Applications

Temperature sensing

B-SENS has a tight expertise in the development of multipoint temperature sensors installed in heavy industries.
3 prominent examples are briefly presented below:
  • Measurement over the wall of a glass oven (dimensions: L 2.90 m – l 1.64 m – H 0.60 m)
  • Temperatures up to 650 °C
  • Several tens of sensors distributed over 2 fibers
  • Stainless steel packaging around the optical fibers
  • Use of a BSI-108 data acquisition system (19 inch rack)
  • Temperature mapping implemented in BSOFT
  • Measurement around a chemical reactor (4.5 m of outer diameter)
  • Temperatures up to 425 °C
  • Several hundreds of sensors distributed over 36 fibers
  • Stainless steel packaging around the optical fibers
  • Use of a BSI-164 data acquisition system (19 inch rack) in an electrical cabinet located 55 meters from the reactor
  • Use of junction boxes for connecting fibers
  • Temperature mapping implemented in BSOFT
  • Measurement in a duct
  • Temperatures up to 1050 °C
  • Several tens of sensors distributed over 7 fibers
  • Bare fibers
  • Stainless steel capillary packaging around the optical fibers
  • Use of a BSI-108 data acquisition system

Strain sensing

B-SENS has developed unique skills in strain sensing and mapping, either with embedded sensors or with sensors glued on the surface of structures.
3 prominent examples are briefly presented below:
  • Strain sensing with cascaded sensors embedded into both glass-fiber-reinforced and carbon-fiber-reinforced composites
  • Embedding of the fibers during the fabrication process of the materials
  • Deployment compatible for use in autoclave systems
  • Measurement in/over concrete for structural health monitoring
  • Possibility to determine the shrinkage during the fabrication process (water release)
  • Strain mapping over large infrastructures
  • Railway traffic monitoring (axle counting)
  • FBG sensors glued on the foot of the rail
  • Connecting optical fibers towards an electrical cabinet localized a few tens of meters from the measurement site

Gas sensing

Hydrogen sensors have been deployed on field over a pipe line section.
  • Use of B-SENS patented technology
  • Extensive lab testing in controlled environments
  • Coated and packaged sensors buried in a field test over a pipe line section
