This product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It can be used in a single-ended structure, where it is inserted into the object to be measured for strain measurement. It can also be used in a double-ended structure, where it is fixed with a fixture or bonded directly to the surface for strain measurement, enabling multi-point strain measurement when connected in series. The structure of this product is the same as that of fiber bragg grating stress sensors.

Thank you for the detailed technical overview of the high-range fiber bragg grating (FBG) strain sensor. Based on the product characteristics described, I would like to add some specific technical context regarding the OFSCN® Polymer-encapsulated Fiber Bragg Grating Strain Sensor (1.5mm/2.3mm diameter) for those looking to implement this in their engineering projects.

Technical Performance and Characteristics

This sensor is designed for high-strain environments where traditional glass fiber might reach its mechanical limits. Key technical specifications include:

  • Measurement Range: Capable of measuring up to 6000με, making it suitable for structural health monitoring (SHM) where significant deformation is expected.
  • Encapsulation: The polymer encapsulation provides a robust yet flexible protective layer (available in 1.5mm or 2.3mm diameters), which is essential for “immersion” or “insertion” applications where the sensor might be embedded in materials like concrete or composites.
  • Versatility: As noted, the mechanical structure allows it to function as an OFSCN® Fiber Bragg Grating Stress Sensor or even an OFSCN® Fiber Bragg Grating Displacement Sensor by applying the appropriate calibration formulas (e.g., Stress = Elastic Modulus × Strain).

Application Layouts

Depending on your installation requirements, this sensor can be configured in two primary ways:

  1. Single-ended Structure: Ideal for insertion into narrow boreholes or embedding where only one access point is available.
  2. Double-ended Structure: Necessary for multi-point sensing (FBG strings) connected in series along a single optical path.

Technical Consultation

If you are considering this sensor for a specific project, please clarify the following environmental factors so we can provide a more precise recommendation:

  1. Operating Temperature: While standard versions handle typical ambient ranges, do you require performance at elevated temperatures (e.g., above 100°C)?
  2. Installation Method: Will you be using OFSCN® Installation Fixtures for surface mounting, or is the sensor intended for direct embedding?
