Condition Monitoring vs Traditional maintenance strategies

The traditional maintenance strategies of “Run to Failure” and “Scheduled Maintenance” are increasingly unacceptable in many process and manufacturing operations. The alternative, to use Condition Monitoring systems (CMS) with predictive capabilities, provides early detection of machinery problems based on collection of machine data. Lower machine maintenance costs and higher availability result when systems are properly installed within a suitable maintenance regime.


Maintenance schedules are generally derived from a conservative viewpoint which often results in regular strip-down and component replacement, even though it may not be necessary. Unnecessary machine overhauls - intended to prevent future faults developing - often do more damage than allowing machines to run without overhaul. This “preventive maintenance” is costly in downtime and spares requirements. Since it does not prevent failures consistently the alternative title, Scheduled Maintenance, is a more apt description.


A more logical strategy would be to identify developing faults (including machine wear) by monitoring the condition of a machine in service. CM is the cornerstone of a predictive maintenance programme which complements scheduled maintenance, enabling longer intervals between routine overhauls. Suitable CM equipment minimises unnecessary maintenance activity and reduces the costs of repairs by detecting fault symptoms before serious damage occurs. However, CM does require investment in equipment and operational resources before returns on the investment are realised as bottom line savings on the maintenance budget.


Condition Monitoring is a generalised method of establishing a machine's health using measured parameters which reflect changes in the machine's mechanical state. Regular monitoring of the mechanical condition of machine trains and the operating efficiency of processes provides data to determine maximum safe operating intervals between overhauls.

CM+ real-time Monitoring

Real-time monitoring


In this mode the Narrow Band Monitoring (NBA) parameters can be monitored and analyzed in real-time, both color coded parameter status and values. Each single NBA object is a narrow band frequency parameter, where the frequency range, alarm limits, real-time values and trends are available in a single screen view. The monitored system and machines with all measuring points and NBA parameters are also available on the left side of the screen in a typical hierarchic windows structure.

Example of analysis software


Maintenance and service planning is always important and often crucial activities for all kind of industrial plants and technical installations in general. But to be able to prepare and make effective service and maintenance plans, forecast analysis is always an important part of any condition monitoring system to be able to predict when condition degradation and fault development will require service activities should take place. Forecast analysis is available for every single analysis parameter and can be used selectively for all kind of defined load conditions. Alarm limits for the parameter in question are also available together with alarm limit prognosis.
