A new approach for maintenance assistance is Acoustic Expert from Primetals Technologies. During the uptime of hardware, different sounds occur, which can give information on the status of the equipment. Recording and analysis of these sounds lead to a wide field of applications for asset but also for process monitoring. This 24/7 acoustic monitoring system enables a new way in predictive maintenance. Applications at environmental plants, steelmaking facilities, casting & rolling and material handling show the universal usability of the described system. Using several example installations the method is described in detail. Achieved results are provided as well.
The main benefits and an outlook conclude the paper.
