Abstract: The invention relates to a method for the calibration of at least one sensor (11-14) of a wind power plant (10). The invention also relates to a wind power plant (10). The calibration process according to the invention is captured by the at least one sensor (11-14). The measurement value (30, 31), which is a measure for the load of a component (15-17), is evaluated, wherein the wind power plant has at least the moveable component (15, 15?, 15?, 16, 17), wherein the component (15-17) is pivoted or rotated around a predeterminable axis (19, 20). The wind power plant according to the invention is provided with a calibration module for the automatic calibration of at least one sensor (11-14), which measures the load of a movable component (15-17) of the wind power plant.

Abstract: A device for producing an aerosol, comprising a liquid line for a liquid flow and a transport gas line for a transport gas flow, comprising at least one injector unit wherein the liquid flow and transport gas flow can be mixed to form an aerosol, also comprising an aerosol line leading to an aerosol discharge arranged in the region of a tool, is known per se. According to the invention, the injector unit comprises flow guiding means for the transport gas flow which define a pressure loss for the transport gas flow, which is lower than the minimum possible pressure loss at the aerosol discharge, by increasing the flow speed and reducing the volume flow. The invention can be used to supply lubricating agents to machine tools.
