Products > Smart FBG Sensors
Fibre Bragg Grating sensors are recorded within the core of a single mode optical fibre, just 9 microns in diameter. Together with the outer cladding and a protective polymer coating, these fiber sensors are truly miniature, generally just 0.15 or 0.25 mm in diameter. For many strain-sensing applications it is practical and appropriate to simply embed or attach these unpackaged SmartFBG sensors within or to the structure under test.
For many other applications alternative sensor constructions are required, for instance to provide a more robust sensor, to provide a sensor with a more distributed strain response, or to offer measurement of other parameters such as temperature, pressure etc. Smart Fibres have developed a range of "Smart" FBG sensors to suit a multitude of applications.
