Fiber Bragg Grating (FBG) Sensors for Advanced Strain Monitoring

Optical fiber sensors designed for real-time, high-resolution strain and pressure
tracking across structural and geotechnical systems

Overview

Fiber Bragg Grating (FBG) Sensors represent a cutting-edge solution for distributed stress, strain, and pressure monitoring in concrete, steel, composites, and other structural materials. These sensors use optical fiber technology to detect wavelength shifts caused by strain or temperature changes. Their compact size, immunity to electromagnetic interference, and ability to support multi-point measurement on a single fiber make them ideal for complex and data-intensive applications. Pressure Stress Measure, a trusted North American B2B company based in Vancouver, BC, offers complete deployment and support for FBG sensor systems. We help customers implement scalable sensing networks that deliver precise, real-time data across long distances and harsh environments. With our focus on research, quality assurance, and end-to-end service, we ensure every solution aligns with your technical and operational goals—backed by field-proven performance and expert guidance.

Case Study 1 – U.S. | Offshore Wind Turbine Monitoring in New Jersey

Pressure Stress Measure deployed FBG sensors on foundation and tower components of an offshore wind turbine. The sensors delivered real-time strain feedback under wind load conditions and helped validate fatigue models. Integration with cloud dashboards provided operations teams with insights to schedule maintenance and reduce downtime.

Case Study 2 – U.S. | Smart Concrete Structure in Texas

FBG sensors were embedded into precast bridge girders during manufacturing. The system captured pre-stress losses, curing deformation, and in-service loading over time. The project team leveraged our analytics software to compare live data against predictive models, optimizing design for future builds.

Case Study 3 – Canada | Rail Tunnel Deformation Study in British Columbia

To monitor deformation across aging rail tunnel linings, a Canadian transportation agency embedded FBG strain sensors along the tunnel’s interior concrete segments. Our engineers provided custom-configured multiplexers and interrogators for real-time alerting. The system identified localized stress zones during thaw cycles, prompting targeted remediation.
