  • MONITORING DEVICE, MONITORING ARRANGEMENT AND MONITORING METHOD FOR MONITORING A SCREW JOINT OF AN OBJECT
    Publication number: 20230314184
    Abstract: A monitoring device for monitoring a screw joint of an object includes a base plate to be attached to the object and a top plate to be attached to one part of the screw joint, wherein the base plate and the top plate are positioned parallel to and on top of each other and wherein both plates each includes at least one electrode that capacitively interact with each other. The monitoring device is characterized in that the electrodes are shaped and positioned such that at least one electrode of one of the plates interacts with at least two different electrodes of the other one of the plates depending on the rotational position of the plates relative to each other. A monitoring arrangement having at least one monitoring device of this kind and a monitoring method are also provided.

  • Nut integrity monitoring device and method
    Patent number: 11053971
    Abstract: An attachment for monitoring a nut of a screw connection for crack formation, deformation, and/or breakage includes a socket portion which is attached to the outer circumference of the nut and has a conductor which is interrupted in the case of a deformation, crack, or breakage of the nut. The conductor is embedded in at least one material. The attachment is produced by injection molding with the conductor embedded within the socket portion. The monitoring attachment is particularly useful for operating a shutoff device for a wind generator in the event of failure of a nut which secures a turbine blade to the generator hub.
