Condition Monitoring

Machine condition monitoring offers the potential for the safe and efficient operation of various forms of equipment.

 For example, by measuring acoustic or vibration signals from operating machinery one can determine whether a system contains faults and whether maintenance action is required. The presence of an incipient fault is often only betrayed by subtle changes in the signal's structure, so that powerful signal processing schemes are required to detect and characterise such faults. The observed signals are commonly highly non-stationary and frequently derive from non-linear processes, so the processing schemes adopted should be tailored to take into account this nature. Further the different modes of failure and different operating conditions mean that the signature of a fault is subject to considerable variability.
