Condition Monitoring: An Overview

Condition Monitoring is the measuring of particular equipment parameters, noting signs of any significant modifications that might be indicative of an impending failure.

What Is Condition Monitoring?

Condition monitoring is defined because the measuring of particular equipment parameters, equivalent to vibrations in a machine, its temperature or the condition of its oil, taking note of any significant modifications that might be indicative of an impending failure. Repeatedly monitoring the condition of equipment and taking note of any irregularities that may normally shorten an asset’s lifespan permits maintenance or other preventive actions to be scheduled to address the difficulty(s) earlier than they become more critical failures.

Condition monitoring is a big component of predictive maintenance. The data collected from condition monitoring over time provides valuable details about the present and historical state of an asset. This evolution of a machine can be used to anticipate how the asset will perform over time and how it may degrade, permitting for the scheduling of upkeep based on these predictions. This is known as predictive upkeep – maintenance based mostly on what failures could happen and what upkeep ought to be scheduled to prevent such failures from occurring.

Condition monitoring methods are typically used on rotating equipment (gearboxes, reciprocating machines, centrifugal machines, etc.), backup or secondary systems, and different machinery similar to compressors, pumps, electrical motors, presses and inside combustion engines.

There are frequent methods used for condition monitoring:

Trend monitoring: Pattern monitoring is the continuous, common measurement and interpretation of data. It includes selecting a suitable and measurable indication of machine or element deterioration and learning this trend to determine when deterioration goes over a critical limit. For instance, pattern monitoring is used for routinely tracking airplane engine data to detect and diagnose irregularities in engine efficiency, hopefully preventing secondary, more pricey damage.

Condition checking: Condition checking includes taking a periodic check measurement with an appropriate indicator while a machine is running. The information from this methodology is then used to measure the condition of the machine at a given time. An example of condition checking could be utilizing an oil sight glass like a condition monitoring pod (CMP) to check the condition of a machine’s lubricant in real time.

Condition monitoring through these two strategies provides an inside look at how your machines and/or components are presently operating and, over time, provides a historical account of machine health.

Benefits of Condition Monitoring

Unsurprisingly, condition monitoring can lend itself to many benefits, together with decreased upkeep costs, reduced downtime, extended asset life and cost financial savings on prematurely changed resources. For example, your condition monitoring system measures the quantity of noise produced by a component. Over time, you discover a trend of machine failure quickly after the noise degree on the part reaches a certain level. Because you’ve a condition monitoring system in place, now you can set an alert on that component when it hits that noise level, which, in turn, lets upkeep personnel know they could wish to consider replacing the component.
