Abstract: A method for fixing a fiber having a fiber Bragg grating sensor segment onto a component configured to undergo changes in strain and/or temperature. The method providing the steps of stretching at least a section of the fiber including the fiber Bragg grating sensor segment by a defined and calibrated preload into a preloaded condition, fixing the section of the fiber including the fiber Bragg grating sensor segment being in the preloaded condition on a carrier element, and fixing the carrier element onto the component, as well as a bearing device with such a fiber.

Abstract: Condition monitoring a cage to detect cage damage by detecting if a conducting material applied to a cage is unbroken or broken. The basic principle of the invention is to integrate a completely passive LC circuit, having the conductive material, on the cage. The LC circuit is magnetically activated and it is externally detectable when conducting material is unbroken or broken. The conducting material of the passive LC circuit is easily broken or worn, being weaker than the cage material. The cage material is non-metallic, such as a polymer material or other suitable synthetic materials.

Abstract: A bearing ring having an elongated sensor element that runs along at least a part of a surface of the bearing ring. The connection between the sensor element and the bearing ring is established by a metallic metal material connected by material bonding with the bearing ring as well as with the sensor element. To improve the life of the bearing a sensor element is arranged in a groove that is machined in the bearing ring. The groove extends from the surface of the bearing ring. The metallic material includes or is connected with a flat metallic strip. The flat metallic strip is arranged at or in the surface of the bearing ring and covers the groove.

Abstract: A sealing assembly including an elastic seal lip having a movable part is provided. The seal lip is configured to be attached to a first part of a machine and to be in contact with a second part of the machine. At least one acceleration sensor is fixed to the movable part of the seal lip, and that assembly further includes a data processing device for processing data obtained from the acceleration sensor. The data processing device is configured to determine the orientation of the acceleration sensor in relation to the direction of gravity.

Abstract: A bearing which includes a bearing ring and rolling elements. The bearing ring includes an outer surface, having a groove around a circumference of the outer surface, wherein the groove is adapted to accommodate a fiber sensor. The bearing further comprises a clamping element, wherein the clamping element retains the fiber sensor with a clamping force acting in a radial direction of the bearing ring such that the fiber sensor intimately engages the bearing ring. Due to the clamping force, relative movement of the fiber sensor can be reduced.

Abstract: The invention provides a sensor, which includes a sensing surface; a housing including a recess, the sensing surface is located at the bottom of the recess, and the recess includes at least one side wall and an opening circumferentially surrounding the sensing surface. A compressed fluid nozzle is provided in the at least one side wall to nozzle compressed fluid from the compressed fluid nozzle to force the substance on the sensing surface to leave from the opening. This design makes it possible to refresh in situ with good efficiency without involving additional mechanical parts, thus reducing the risk of sensing surface damage, such as scratch wear, in the presence of wear particles.

Abstract: The invention relates to a load measuring device including a deformable component configured to be deformed under a load to be measured and a sensor assembly attached to a first portion of the deformable component and to a method for determining load using such a sensor assembly. It is proposed that the sensor assembly includes at least one acceleration sensor configured to detect a change in an orientation of the first portion with regard to the direction of gravity and that the deformable component is formed as a seal configured to be in sliding contact with a component configured to rotate in relation to the seal.

Abstract: An assembly providing a bearing, a lubricant and a contamination sensor for determining a level of contamination in the lubricant. The sensor includes an EM wave generator for generating an EM signal, and an EM sensing element arranged in contact with the lubricant. The EM sensing element receives the generated EM signal and transmits an output signal whose properties are responsive to real and imaginary parts of a complex relative permittivity of the lubricant. The output signal is received by an EM measuring device that measures first and second parameters of the output signal, which are respectively representative of the real and imaginary parts of the complex relative permittivity. The EM measuring device determines a level of water contamination in the lubricant, based on the measured first parameter alone and determines a level of metal particle contamination in the grease, based on the measured first and second parameters.
