Beschreibung
Zusammenfassung:	The invention relates to a method for monitoring the dynamic behavior, in particular of the oscillating behavior of a rotating shaft, the oscillation being detected by at least two sensors at defined different spatial position, the oscillating behavior in at least one preferred direction being determined from the oscillation. The invention also relates to a device for monitoring oscillating behavior in a rotary machine with rotatable parts, having at least two sensors, a shaft and a computing unit, characterized in that the at least two sensors are positioned in a defined spatial position outside the shaft, detect measurement variables which characterize the oscillations and are connected to a computing unit for the transfer of data. The invention also relates to a gas turbine and a steam turbine that use a method and a device as per the invention.
