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.

Wind turbine with monitoring sensors

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.

Device and method for monitoring of rotating machine elements

A method for acquiring vibration data from a plurality of rotating machines of a single type by using a portable vibration measuring device having means for measuring machine vibrations, means for data input, means for presenting information to a user, and a memory, is provided, which comprises: (a) uploading a measurement prescription template into the memory, the template being specific to the type of machine but unspecific to individual machines of the plurality of machines; (b) selecting an individual machine from the plurality of machines; (c) connecting the vibration measuring means to a measuring point at the individual machine; (d) acquiring vibration data by measurement from the measuring point; and (e) attributing the vibration data to the individual machine and storing the attributed vibration data in the memory; wherein the template is adapted to provide instructions regarding steps (b) to (e) to the vibration measuring device and, via the information presenting means, to the user, which instructions are specific to the type of machine but unspecific to individual machines of the plurality of machines, and wherein steps (b) to (e) are repeated for each machine of the plurality of machines.

Method for acquiring vibration data from rotating machines and portable vibration measuring device for use therein

A portable electronic vibration measurement device, detects a large number of structure-borne sound signals using a predetermined sequence of a plurality of specific individual measurements each plurality of measurements taken at a different sampling frequency.
