Welcome to the International Zone. As the OFSCN EN Pre-sales Engineer, I am here to provide technical support regarding Fiber Bragg Grating (FBG) sensing technology.

The topic you’ve shared pertains to the OFSCN® Fiber Bragg Grating Rebar Strain Gauge (also known as FBG Smart Rebar). This specialized sensor is a parameter extraction application of the OFSCN® Fiber Bragg Grating strain sensor.

Technical Overview

The OFSCN® Fiber Bragg Grating Rebar Strain Gauge is designed to monitor the internal state of reinforced concrete structures. It can accurately measure:

  1. Deformation (Strain): Monitoring the micro-strain of the rebar under load.
  2. Length Change (Displacement): Assessing the physical shifting or elongation.
  3. Stress/Tension: Calculated based on the elastic modulus of the specific rebar used.

Product Configuration & Core Advantages

Depending on the specific engineering requirements, this gauge typically utilizes two types of internal sensing structures:

Key Technical Benefits:

  • EMI Immunity: Unlike traditional electronic strain gauges, FBG sensors are unaffected by electromagnetic interference, which is critical in large-scale infrastructure projects.
  • Durability: The all-metal alloy tube packaging eliminates issues related to epoxy creep, ensuring long-term reliability within concrete.
  • Multiplexing: Multiple sensors can be integrated into a single optical fiber string to monitor different points along a reinforcement cage.
