  • Patent number: 10302501
    Abstract: A measuring device is provided which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured. The surface supports the measuring device. The measuring device comprises at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle. The projecting contact surfaces, when the measuring device is placed on the surface of an object being measured, lie against the surface and are supported by the surface. A first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.

  • Patent number: 9324037
    Abstract: Method for monitoring of a wind power plant operated in variable operating states. Start sensor data is obtained in at least one basic operating state of the machine; based on the start sensor data, a starting model with a rule set for conducting the monitoring is set up, the rule set determining which parameters are to be monitored, in which manner and with which weighting and which sensor data are to be obtained and used for this purpose; a reference SOM is prepared using the rule set with sensor data selected using the rule set and obtained in a reference operating phase of the machine; during a monitoring operating phase, time characteristics of a quantization error of the sensor data selected using the rule set being tracked with respect to the reference SOM, troubleshooting being started if the quantization error meets a criterion which is dictated by the rule set.

  • Patent number: 8672625
    Abstract: A vibration-resistant wind turbine and process for operation is provided. The wind turbine has a rotor with at least two blades, each of which includes an inclinometer arrangement with at least two axes, and an evaluating unit. The evaluating unit determines the bending and/or twisting of the blade relative to the longitudinal axis of the blade on the basis of signals from the inclinometer arrangement for each blade during operation. Each rotor blade further has at least one liquid tank which is capable of receiving or transferring liquid from or to a liquid reservoir via a transfer mechanism in response to the determined bending and/or twisting of the rotor blades to reduce vibration caused by imbalances, thereby extending the service life of the wind turbine.

  • Patent number: 8578772
    Abstract: A rotating machine element is monitored for displacements using co-rotating sensors for acceleration, rotation or the direction of gravitation. In doing so, the sensor data are received by a, likewise, co-rotating electronic unit. The data can also be stored and further processed in this electronic unit.

  • Publication number: 20110049886
    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.
