Data acquisition system
BSI suite
Our spectrometer-based BSI-1XX interrogators have independent optical channels to measure up to 40 wavelength-division-multiplexed fiber Bragg gratings (FBGs) cascaded per optical channel at high speed.
Standard BSI-108, BSI-116, BSI-132 and BSI-164 units feature 8, 16, 32 and 64 independent channels, respectively. Several hundreds of sensors can then be interrogated with a single device!
BSI-108 and BSI-116 units can be assembled in a benchtop frame or in a 19-inch rack. Other units are exclusively provided in a 19-inch rack. In terms of optical connectors, FC/APC or SC/APC are standard.
This suite of interrogators is suitable for static and dynamic applications like temperature sensing, structural health monitoring or condition monitoring.
Such devices are provided with a fully customizable interface that can be optimized depending on customer’ specifications.
FBG
B-SENS has accessed to up-to-date facilities to manufacture Bragg gratings in different single-mode fiber types.
Uniform and tilted Bragg gratings can be produced by the phase mask technique or the Lloyd mirror configuration.
Uniform gratings can be used as filters in telecom applications or for temperature and strain sensing.
Tilted gratings enable refractometric and multiparameter sensing.
The following specifications can be reached:
These gratings can be supplied bare or packaged and/or connected (FC/APC or SC/APC).
FBG sensors
(High) Temperature
FBG temperature sensors are suited for a large range of applications where quasi-distributed static or dynamic measurements are essential. They are provided with PTFE or stainless steel capillary tubing, depending on the target temperature range.
For high temperature sensing, a safe & continuous use is ensured up to 650 °C. Sensing up to 1050 °C can be achieved depending on the actual conditions.
These temperature sensors ensure intrinsic immunity to electric sparks and electromagnetic and radio-frequency interferences. They combine compact size, high resistance to corrosion and harsh environments, and a long-term reliability.
A single optical fiber can replace tens of temperature probes!
Strain Monitoring
FBG axial strain sensors are suited for a large range of applications ranging from structural health monitoring to condition monitoring.
They are either embedded in the structures (concrete, composite, …) to monitor or glued in their surface.
These sensors ensure quasi-distributed static or dynamic strain measurements. They are intrinsically immune to electric sparks and electromagnetic and radio-frequency interferences. They combine compact size, high resistance to corrosion and harsh environments, and a long-term reliability.
A single optical fiber can replace tens of strain gauges!
Hydrogen detection
Patent : Gas Sensor UK0707303.4
Hydrogen sensors are based on a fiber Bragg grating (FBG) coated with a specific sensitive layer that undergoes an exothermic reaction in the presence of hydrogen in air.
Theses sensors are provided in a metal case packaging also comprising a bare FBG to get a temperature-compensated response.
The technology is patented (EP2140249) and is designed to detect low concentration molecular hydrogen leakages (limit of detection: 0.1 % of H2 in wet air at ambient temperature).
Other advantages of this solution are its small dimensions, multiplexing capabilities and numerous customization options.

Early flame detector
Patent : Infrared Sensor GB10042150.8
Early flame detectors are based on a fiber Bragg grating (FBG) coated with a specific sensitive layer that is sensitive to the infrared radiation. Theses sensors are provided in a metal case packaging also comprising a bare FBG to get a temperature-compensated response.
The technology is patented (EP2547993) and has been extensively tested according to the EN 54-1 norm. The IR sensor can detect a ~1 dm 3 fire at a 6-meter distance within a few tens of seconds, which is optimal for use in wide infrastructures including parkings and tunnels.
Other advantages of this solution are its small dimensions, multiplexing capabilities and numerous customization options.
