Condition Monitoring: An Overview

Condition Monitoring is the measuring of specific equipment parameters, noting signs of any significant adjustments that may very well be indicative of an impending failure.

What Is Condition Monitoring?
Condition monitoring is defined as the measuring of particular equipment parameters, similar to vibrations in a machine, its temperature or the condition of its oil, taking note of any significant modifications that could possibly be indicative of an impending failure. Constantly monitoring the condition of equipment and taking note of any irregularities that will usually shorten an asset’s lifespan permits upkeep or other preventive actions to be scheduled to address the problem(s) earlier than they become more serious failures.

Condition monitoring is a big component of predictive maintenance. The data collected from condition monitoring over time provides valuable information about the current and historical state of an asset. This evolution of a machine can be utilized to anticipate how the asset will carry out over time and the way it may degrade, permitting for the scheduling of maintenance primarily based on these predictions. This is known as predictive maintenance – upkeep primarily based on what failures might happen and what upkeep must be scheduled to stop such failures from occurring.

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

There are two frequent strategies used for condition monitoring:

Development monitoring: Development monitoring is the continual, common measurement and interpretation of data. It entails selecting a suitable and measurable indication of machine or part deterioration and learning this development to determine when deterioration goes over a critical limit. For example, trend monitoring is used for routinely tracking airplane engine data to detect and diagnose irregularities in engine performance, hopefully stopping secondary, more pricey damage.
Condition checking: Condition checking involves 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 might be using 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 methods provides an inside look at how your machines and/or parts are at the moment working and, over time, presents a historical account of machine health.

Benefits of Condition Monitoring
Unsurprisingly, condition monitoring can lend itself to many benefits, including decreased maintenance costs, reduced downtime, prolonged asset life and value savings on prematurely modified resources. For instance, your condition monitoring system measures the quantity of noise produced by a component. Over time, you discover a pattern of machine failure quickly after the noise degree on the element reaches a sure level. Because you’ve got a condition monitoring system in place, you can now set an alert on that element when it hits that noise degree, which, in flip, lets upkeep personnel know they might wish to consider replacing the component.
