OFSCN® ultra-high-range fiber Bragg grating strain sensors are commonly used in various environments, including dams, bridges, tunnels, large crane booms, surfaces inside e outside buildings, concrete surfaces e interiors, highway roadbeds, tunnels, e areas prone to landslides. They can be used in fields such as transportation, tunnels, large-scale machinery, giant antennas, environmental protection, e advanced scientific research.

Measurement Range e Product Details of OFSCN® Ultra-High-Range Fiber Bragg Grating Strain Sensor:

The measurement range of OFSCN® ultra-high-range fiber bragg grating strain sensors can be customized, with a minimum range greater than 30,000 με (3% strain), typical ranges of 100,000 με (10% strain), 200,000 με (20% strain), e 300,000 με (30% strain). The structure of the product varies depending on the customized range.

Advantages of OFSCN® Ultra-High-Range Fiber Bragg Grating Strain Sensor:

Compared to traditional resistive strain gauges, OFSCN® ultra-high-range FBG strain sensors enable continuous real-time online strain measurement. They are not affected by environmental conditions such as air quality (haze, rain, snow, obstruction), ensuring accurate measurements with rapid response (millisecond-level response).

Compared to various electric signal strain sensors based on current, resistance, voltage, capacitance, and Outro technologies, OFSCN® ultra-high-range FBG strain sensors are based on fiber optic communication and fiber optic sensing. Therefore, they are not affected by electromagnetic interference and can work in various strong and weak electromagnetic environments.

Compared to traditional resistive strain gauges, OFSCN® ultra-high-range FBG strain sensors have a longer length, allowing for the measurement of large displacements e a wider range of environmental or object monitoring. This helps save on the number of sensors used e reduces costs.

OFSCN® ultra-high-range FBG strain sensors are digital, recordable, e network-enabled sensors. They are easy to deploy e have flexible lengths. The strain information can be monitored without the need for visual observation. The FBG strain sensing system formed by these sensors can monitor strain information in large spaces, over long distances, e across multiple targets, providing a wide spatial coverage range.
