Three directional (BC-T4) fiber Bragg grating strain sensor

Product Introduction: Fiber Bragg Grating sensors have many advantages in ship structural monitoring. Fiber Bragg Grating sensors are increasingly widely used in engineering structure sensing due to their technical advantages such as anti electromagnetic interference, high sensitivity, small size, light weight, good stability, and long signal transmission distance. Sensors detect temperature, stress-strain, vibration, acceleration, and fuel conditions, and require higher weight and smaller size for the sensors. This is precisely the advantage of fiber Bragg grating sensors. Contact us for information download

1. Small size: The packaged size of the three-way strain sensor is only 112 × 112 × 34mm. The small size of the sensor means that it has little impact on the monitored object and is less likely to be accidentally damaged.
2. Large range: The strain range that can be utilized by the fiber Bragg grating itself is only ± 2000 μ ε, while the designed three-way (BC-T4) fiber Bragg grating strain sensor, due to its special desensitization structure and the use of materials with low elastic modulus and high yield stress, has a range of ± 4000 μ ε, greatly improving the range and application range of the fiber Bragg grating sensor.
3. High precision: The desensitization structure design of the three-way (BC-T4) strain sensor adopts a special three ring structure with an appropriate desensitization coefficient, which improves the accuracy of the sensor.
4. Temperature compensation: A temperature compensation substrate is added above the three-way (BC-T4) sensor to achieve temperature compensation, improving the accuracy of engineering applications.
5. Long term stability and high lifespan: Due to the use of laser welding for the connection between the sensor desensitization structure and the base, there is no long-term creep or aging problem that occurred with organic bonding methods before. It is relatively stable and reliable during long-term operation, and its service life is greatly improved.
6. Simple installation process and high reliability: Due to the use of argon arc welding, the installation process is simple and does not require complex treatment of the welding surface, thus avoiding installation problems caused by inadequate surface treatment. And the welding equipment is relatively small, even small spaces can be welded.
7. Low cost: Due to the reduction of fiber Bragg gratings and the simplification of their structure, their cost is reduced, making them easier to apply on a large scale.
