Abstract: A device for detecting vibrations on a machine (12) with at least one machine element (11) which rotates around an axis of rotation, with a measurement head (1) for detachable coupling to at least one measuring point (13, 61, 62, 63) of the machine, with a sensor arrangement (2) for measuring vibrations in at least one sensor measurement direction which is fixed with respect to the measurement head, and an arrangement (42, 43, 44, 45) for detecting the current three-dimensional orientation of the sensor measurement direction, with at least one gyroscope (42, 43, 44), and an arrangement (46) for assignment of vibration measurement and the corresponding orientation of the sensor measurement direction during the respective vibration measurement.
