摘要： A method for determining a rotational speed of a rotatably mounted component of a machine is disclosed, wherein image data of a marked region of the machine component are obtained in the form of a plurality of frames via a video camera, and the image data are evaluated, in order to determine the periodicity of the rotation of the machine component from the change over time of the image data in the frames of the machine component. The video camera is configured by selecting an active region for obtaining the image data from the total number of pixels of the video camera, in which an observation area is imaged, which is passed through by the marked region during the rotation of the machine component, wherein the active region comprises only a portion of the total number of pixels of the video camera, to increase the frame rate correspondingly.

摘要： A probe device for a rotating head has at least one support arm that is mounted so as to rotate around an axis of rotation, at least one probe that is joined to the support arm, and at least one spring element that can be supported on the rotating head and engages at the support arm and that is provided for exerting a force on the support arm, which, as a result of this force, experiences a torque with respect to the axis of rotation. The support arm has at least one mount, which is concentric with the axis of rotation, for the spring element, which, when arranged on the mount, is bent at least in part around the axis of rotation. As a consequence, centrifugal forces that act on the spring element when the rotating head is in operation have no influence on the tension of the spring element.

摘要： Disclosed herein is a differential probe, a testing device having at least one such differential probe, and a method for producing the same. The differential probe has a first half-probe and a second half-probe, at least one conductor loop pair having a conductor loop of each half-probe being shaped mirror-inverted relative to each other and, in respect of a mirror-inverted arrangement thereof on respective sides of a mirror plane. The conductor loops are oriented parallel to the mirror plane, are arranged offset relative to each other in an offset direction, also parallel to the mirror plane, wherein the conductor loops overlap in part in the direction normal to the mirror plane.

摘要： A device for sensing mechanical vibrations of measurement objects that can be attached to measurement objects for this purpose comprises a housing, at least one vibration sensing element and at least two current sources. Here, the vibration sensing element and current sources are arranged inside housing, and current sources are arranged along at least one circle around the vibration sensing element, wherein identical angular distances are provided each time between adjacent current sources of the same circle. Based on this symmetric construction, the vibration behavior of the device is improved, which favorably affects the linear measurement behavior of the device.
