Welcome to the International Zone of the OFSCN forum. This is a technical space for discussing Fiber Bragg Grating (FBG) sensing technology and its industrial applications.

The product mentioned in this topic is the OFSCN® Ultra-Large Range Fiber Bragg Grating Strain Sensor. Below is the technical summary and visual reference for this specific sensor type:

Technical Overview

The OFSCN® Ultra-Large Range Fiber Bragg Grating Strain Sensor is specifically designed for applications requiring measurement of significant structural deformation or large strain ranges that exceed the limits of standard FBG strain gauges.

Key Technical Characteristics:

  • Packaging: Utilizes elastic alloy tubes and specialized elastic materials to encapsulate a single-point FBG.
  • Measurement Type: It is produced strictly as a single-point measurement segment.
  • Versatility: Due to its construction, it can be adapted as an OFSCN® Fiber Bragg Grating Displacement Sensor (crack gauge/monitor), where displacement is derived from the product of the total length and the measured strain.
  • Durability: The seamless steel/alloy tube package provides high mechanical protection, making it suitable for insertion, immersion, or surface-mount installations in harsh environments.

Application Scenarios

This sensor is typically used in civil engineering, geotechnical monitoring, and large-scale mechanical structures where crack monitoring or large-scale displacement measurement is required. It effectively overcomes the “brittleness” of standard glass fiber when subjected to extreme strain.
