Fibre Optic Strain Gauges are designed based on Fibre Bragg Grating (FBG) technology. They are used in structural health monitoring applications, where foil-type strain gauges could not perform well. These strain sensors exhibit an intrinsically high multiplexing capability which minimizes the noise generated from longer cables and reduces installation complexity. They do not require electrical power supply to operate, but instead they rely on light that propagates through a fibre.
Fibre Optic Strain Gauges are ideal for huge projects such as a tunnel or pipeline monitoring, structural health monitoring of bridges, buildings and even infrastructure monitoring in mining site and condition monitoring of machinery in industrial processing plants. The ease of installation reduces the plant complexity and installation costs.
