Structure and Composition of OFSCN® Ultra-High-Range Fiber Bragg Grating Strain Sensor:
The OFSCN® ultra-high-range fiber bragg grating strain sensor consists of fiber connectors, all-metal stainless seamless steel tubes/high-polymer elastic materials, FBG, and other packaging components. When combined with a FBG demodulator, it can form an ultra-high-range FBG strain sensing system or a high range FBG displacement sensing system.
Deployment Methods of OFSCN® Ultra-High-Range Fiber Bragg Grating Strain Sensor:
The OFSCN® ultra-high-range fiber Bragg grating strain sensor can be directly installed with clamps at both ends, welded, bundled, surface-mounted with adhesives, encapsulated after being inserted into the tested object with adhesives, or directly embedded in concrete, etc. In some special applications, special fixtures can be designed to assist in sensor deployment.
Operating Environment and Application Industries of OFSCN® Ultra-High-Range Fiber Bragg Grating Strain Sensor:
OFSCN® ultra-high-range fiber Bragg grating strain sensors are commonly used in various environments, including dams, bridges, tunnels, large crane booms, surfaces inside and outside buildings, concrete surfaces and interiors, highway roadbeds, tunnels, and areas prone to landslides. They can be used in fields such as transportation, tunnels, large-scale machinery, giant antennas, environmental protection, and advanced scientific research.
Measurement Range and 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), and 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 other 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 and a wider range of environmental or object monitoring. This helps save on the number of sensors used and reduces costs.
OFSCN® ultra-high-range FBG strain sensors are digital, recordable, and network-enabled sensors. They are easy to deploy and 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, and across multiple targets, providing a wide spatial coverage range.
