How is the fiber fixed onto an ultra-thin metal sheet to enable spot-welding installation?
For patch-type fiber Bragg grating (FBG) strain gauges designed for spot-welding installation, the optical fiber is precisely secured onto an ultra-thin metal sheet during the manufacturing process. This metal sheet acts as the base for the sensor, providing a stable platform for the FBG and an interface for direct spot welding onto the target structure. This method ensures robust mechanical coupling and accurate strain transfer from the host material to the FBG.
OFSCN® offers OFSCN® Fiber Bragg Grating strain sensor (patch type), which is suitable for both adhesive bonding and spot-welding installation methods.
