vibration and temperature can help identify possible causes. For example, vibration patterns can help identify the root cause. ■ Planning preventive maintenance can be aided by monitoring both temperature and vibration. A gradual temperature rise is not necessarily as much of a problem as increasing vibrations that can demand more immediate correction. ■ Learn how to improve longer-term asset selection and utilization using sensor data to identify potential operating limitations before they become problems. When temperature and vibration need to be monitored, EHM
■ Uses data for trend analysis as well as real-time monitoring to identify conditions like: ■ Misaligned or imbalanced systems ■ Worn or loose components ■ Excessive bearing wear ■ Improperly mounted or driven motors ■ Over temperature conditions ■ Proactively sends alerts to the host controller or the Cloud Vibration and temperature Vibration is not the only clue that a machine might need preventative maintenance. A rising temperature
trend can also alert the EHM system of potential problems, especially if the rising temperature is correlated with increasing vibrations. Combining the two parameters gives a more complete picture of the equipment’s condition. They can alert operators to different sets of conditions and provide multiple benefits: ■ Vibration can identify mechanical issues like misalignments, imbalances, bearing wear, etc. ■ Temperature increases can identify electrical problems like overheating windings or lubrication problems. ■ When detecting anomalous operation, correlating out-of-band
