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!

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.

The µBSI is a smart and lightweight device that can be battery-operated. Based on a tunable laser source, it is specifically developed to provide a cost-effective solution for up to 4 wavelength-division-multiplexed FBGs sensors cascaded along a single optical fiber. It is the most competitive solution for a low amount of sensing points!

This interrogator is suitable for static and dynamic applications like temperature sensing, structural health monitoring or condition monitoring.

It is provided with a dedicated interface and can communicate through Bluetooth with a smartphone/tablet.

FBG temperature sensors are suited for a large range of applications where quasi-distributed static or dynamic measurements are essential. They are provided with PFTE 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.

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.

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 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.
