Welcome to the OFSCN® Technical Inquiry forum.

The OFSCN® Fiber Bragg Grating Displacement Sensor mentioned in this topic is a specialized application of our FBG strain sensing technology. It extracts displacement parameters based on the physical relationship: Displacement = Total Length × Strain.

Technical Overview

This sensor is primarily designed for monitoring structural health, such as crack expansion in civil engineering or relative displacement in geological monitoring.

  • Standard Implementation: Most of our displacement sensors are based on the OFSCN® Ultra-Large Range Fiber Bragg Grating Strain Sensor.
  • Calibration: Each unit undergoes factory displacement-wavelength calibration. The calibration formula is typically linear, provided in units of μm/pm or mm/pm.
  • Configurations: Unlike standard strain strings, displacement sensors are generally produced as single-measurement segments to ensure accuracy over the displacement range.

Consultation for Application

To provide a precise technical recommendation for your project, could you please clarify the following:

  1. Measurement Range: What is the maximum expected displacement or crack width change you need to monitor (e.g., 5mm, 50mm, or larger)?
  2. Installation Environment: Will this be installed on a concrete surface, steel structure, or in a soil/rock environment?
