Sentea - Model SR-1080, DM-4120 and DM-8120 -Structural Health Monitoring Mini-Interrogator

Edge computing

Sentea interrogators feature standard data interfaces and an open platform for seamless system integration.

Reliable measurements

Thanks to their patented polarization scrambler and temperature control features, Sentea interrogators offer remarkable short and long-term acquisition stability.

Cost-effective

Sentea leverages the benefit of silicon photonics to make fiber optic sensing affordable, and deployable at large scale.

Embedded fibers
Use them to measure load, torque, temperature, shape or pressure. These fibers come pre-installed on steel or composite subsystems such as bearings, blades, storage vessels and tanks.

Sensing patches
Suitable for measuring strain or temperature. They are easy to install and can be glued to flat or curved surfaces.

Fiber sensors
These sensors measure strain, temperature, acceleration as well as tilt and displacement. They can be welded, glued or secured with screws and magnets, ensuring easy installation.

Continuous sensing along large structures with a single fiber
Our interrogators are available with 1, 4 or 8 channels. Each channel can be used to monitor an optic fiber or several serially connected sensors. Optic fibers can be deployed over several kilometers, enabling you to reliably monitor the health and condition of your remote assets.

High speed and high volume data acquisition

• Our interrogators send light into the fiber, read out the reflected light, and correlate it to strain, temperature, and other parameters.
• They owe their exceptional compactness to silicon photonics, a technology that allows us to integrate all optical functions onto a single chip.
• Silicon photonics has been used in telecom and datacom applications for more than a decade now and is gradually replacing older bulk optics in all photonics applications thanks to its scalability and low cost, using the same fabrication processes as electronic chips.

The right data, wherever you want it

• The interrogator can send data to your control system or monitoring room via a variety of hardware interfaces and communication protocols for seamless integration with your structural integrity and predictive maintenance monitoring application.
• Moreover, thanks to edge computing, our interrogators can already independently pre-process part of the massive amount of data that is gathered.
