Practical Case

In a large petrochemical plant, the BENTLY 3500/25 is used in the rotating equipment monitoring system. It monitors the vibration and shaft position of a key compressor. Once, during operation, it detected abnormal vibration signals in advance. Through trend analysis and accurate measurement, maintenance personnel were able to quickly identify loosening of some internal components. Thanks to the 3500/25’s reliable performance, timely maintenance was carried out, avoiding a potential breakdown that could have led to production shutdowns and huge economic losses.
