New from HBM, the OptiMet system of fibre-optic components includes optical sensor gratings in addition to a comprehensive product range.
The OptiMet system comprises mono- mode optical fibres with integrated functional gratings, fibres without gratings, interrogators that evaluate the signals from optical strain gauges (SG) and the recently developed X120 adhesive, which comes with a special mixing nozzle and applicator. The range provides users with all the components available for successful optical SG applications.
HBM developed its fibre-optic SG, based on Bragg grating technology, as an alternative to the proven standard electric SG that have been used for decades in mechanical stress analysis. Strain is measured with light in optical SG so that an electric signal is not needed. This gives an SG with higher insensitivity to electro- magnetic interference, high voltage, potential differences and humidity.
