In the paper a simple unsupervised monitoring method of rotary machines is proposed. The method consists of three stages – multi-reference preliminary analysis of the vibration signals, auto-reference preliminary analysis and probabilistic analysis of the signals. The method is tested by using signals from eight machines. The efficiency of the method has been positively verified.
