摘要：Device for measuring bending in mechanical constructions, comprising threesensors in a cylindrical housing (150) provided with three inner cavities (102, 104, 106) andfour anchoring points (110, 111, 112, 113) which carry and fix an optical fibre (120)extending through the device. The optical fibre (120) comprises three Bragg gratingslocated in first, second and third cavities (102, 104, 106), respectively. The dimensions ofthe cavities and prestressing of the gratings (121, 122, 123) gives different wave lengthshift for the three gratings as a function of bending, tension and temperature,respectively, thus the bending load can be measured accurately.
