The OFSCN® Fiber Bragg Grating Pipeline Pressure Sensor is a specialized application of FBG strain sensing technology, specifically designed for monitoring circumferential deformation and internal pressure in pipelines.
Technical Principles and Features
- Transduction Mechanism: This sensor functions by converting the pipeline’s circumferential strain (hoop stress) into a wavelength shift. As internal pressure changes, the pipeline expands or contracts, which is captured by the FBG element.
- Core Technology: It is built upon the OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor architecture. The use of a seamless metal tube for packaging ensures high reliability and eliminates the creep issues common with traditional adhesive-based sensors.
- Installation: The system typically utilizes the OFSCN® Installation Fixture to ensure a rigid and stable mechanical coupling between the sensor and the pipeline surface.

Application Scope
This sensing system is suitable for long-term monitoring of oil, gas, or water pipelines where electromagnetic interference (EMI) resistance and high durability are required.
If you are considering this for a specific project, could you please clarify the maximum operating temperature and the pipe material (e.g., steel, composite) involved? This will help in determining the optimal mounting method and sensor specifications.
