Abstract
A method and a device for measuring the loading on rotor blades, especially of wind power plants with swiveling rotor blades, the loading of the rotor blades being determined by way of deformation of a bearing ring of the swiveling rotor blade takes place economically with proximity sensors, but can also take place advantageously with fiber optic sensors. With an electronic evaluation device, the deformation of the bearing ring is referenced to the loading of the rotor blade. In one advantageous embodiment, an inclinometer is also provided.
