The product is a high-range fiber bragg grating strain sensor (FBG strain gauge) used for strain measurement. It is a single-ended structure that can be inserted into the test object for strain measurement, fixed using fixtures, or adhered with adhesive tape for strain measurement. The maximum range is approximately 25000 to 30000 microstrains (30000με).

Regarding the OFSCN® Seamless Steel Tube Packaged FBG Strain Sensor mentioned in this topic, it is a high-durability solution designed for demanding engineering environments. Unlike traditional foil strain gauges, this sensor utilizes a specialized mechanical structure that allows for a significantly higher measurement range.
Technical Overview
Fiber Bragg Grating (FBG) strain sensors operate based on the shift of the reflected wavelength caused by mechanical deformation. This specific seamless steel tube model offers several technical advantages:
Extended Range: While standard FBG strain sensors often handle up to 3,000 or 5,000 με, this seamless steel tube package supports a maximum range of 25,000 to 30,000 microstrains (με).
Protection & Durability: The seamless steel tube provides high mechanical strength, protecting the fragile fiber inside from lateral pressure and environmental damage.
Versatile Installation: The design supports insertion (immersion) into materials like concrete or soil, surface mounting via fixtures, or adhesive bonding.

Application Guidance
To ensure the correct technical configuration for your project, please consider the following:
Installation Method: Do you intend to embed this sensor into a material (e.g., concrete/composite) or mount it onto the surface of a metal structure?
Temperature Compensation: Strain measurements are sensitive to temperature fluctuations. Do you require an integrated temperature compensation FBG within the same housing, or will you be using a separate OFSCN® FBG Temperature Sensor?
