What is the typical strain transfer efficiency (coefficient) of your Fiber Bragg Grating (FBG) sensors?
The strain transfer efficiency (or coefficient) of a Fiber Bragg Grating (FBG) sensor refers to how effectively the strain from the structure being monitored is transferred to the FBG element within the sensor itself. Ideally, this coefficient is 1 (or 100%), meaning the FBG experiences the exact same strain as the host material. In practice, factors such as the packaging material, adhesive layers, and installation method can influence this transfer, leading to a coefficient slightly less than 1.
For OFSCN® FBG strain sensors, our products are designed and manufactured to maximize this efficiency, ensuring accurate and reliable strain measurements. Each OFSCN® FBG strain sensor undergoes factory calibration, providing a specific strain-wavelength calibration formula (typically in units of με/pm). This calibration inherently accounts for the sensor’s overall response to applied strain, which includes the effects of strain transfer.
We offer various types of FBG strain sensors tailored for different applications and environments, each optimized for efficient strain transfer:
- OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor: Designed for robust performance in various environments, including high temperatures.
- OFSCN® Polymer-encapsulated Fiber Bragg Grating Strain Sensor: Available in different diameters for specific installation requirements.
