Device for sensing mechanical vibrations
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.
