Temperature Compensated Steel Sheet Type Fiber Bragg Grating Strain Sensor︱OSC3155

Description:

osc3155A strain sensor featuring built-in temperature compensation and fiber Bragg grating technology.

osc3155Sensors are suitable for strain measurement on outdoor steel structural surfaces.osc3155Sensor substrate made of stainless steel, serving as a protective layer for the optical fiber during installation. The grating is mounted on the stainless steel substrate material, in a pre-stretched condition.osc3155Strain sensors utilize a glueless encapsulation technique, ensuring long-term reliability.

osc3155Design of grating strain sensorsosc3150Similar to sensors, butosc3155An additional temperature compensation grating has been added. The benefits of this design include: one is the higher precision of temperature compensation due to the closer proximity of the strain grating and the temperature compensation grating; the other benefit is the saving of installation time and cost, as an additional temperature compensation grating sensor does not need to be spliced.

osc3155The grating strain sensor is easy to install.It takes just a few minutes. Due to the spot welding installation, the sensor is ready for use immediately after installation, unlike adhesive sensors that require waiting for the adhesive to cure. The sensor's two ends are equipped with armored fiber optic cables, simplifying both installation and tail fiber protection. For long-term monitoring, it is recommended to cover the sensor with a protective material after installation to ensure its long-term monitoring performance.

The comparative test results with the resistive strain gauge show that:osc3155Grating strain sensors have the same sensitivity and accuracy as strain gauges, butosc3155The range of the grating strain sensor is greater, and its fatigue life is longer than that of the resistive strain gauge.100Multiple.osc3155The grating strain sensor is suitable for use in various harsh environments, boasting the inherent advantages of fiber Bragg grating sensors.
