Predictive Maintenance

What is predictive maintenance?

Predictive maintenance combines asset data with predictive analytics to estimate when a machine is likely to fail, enabling maintenance teams to take action before unplanned downtime occurs.

Using a variety of hardware and software solutions, including vibration monitoring, early faults can be detected to alert maintenance leads before a catastrophic failure occurs. To be effective, this data must be properly preprocessed and analyzed.

When implemented correctly, a predictive maintenance program helps manufacturers optimize plant resources, reduce maintenance costs, and improve overall equipment effectiveness (OEE).

Predictive maintenance vs. preventive maintenance

Unlike predictive maintenance, preventive maintenance doesn’t rely on collected data about the real-time condition of the asset. Instead, machines are maintained and inspected at regular intervals. This approach depends on the ability of the inspector to identify machine health issues—often, small problems don’t become evident until they are large problems.

The goal of preventive maintenance is to prevent machine failure and avoid reactive maintenance. Actual results vary based on how closely the maintenance team is able to stick to the schedule and how good they are at identifying problems before machine failure is imminent.

Predictive maintenance vs. condition monitoring

The definition of condition monitoring has evolved since this practice was first widely implemented. Initially, condition monitoring alerts meant that a failure was already occurring and needed to be addressed immediately. Today, it means observing the overall condition of your assets via route-based or continuous monitoring, helping you prioritize and optimize your limited maintenance resources.

As technology and techniques advanced, predictive maintenance programs were able to make use of condition monitoring to help forecast machine failure and reallocate maintenance resources to that asset. Condition monitoring is just one necessary component of a larger predictive maintenance program.

When predictive maintenance falls short

One of the biggest challenges with predictive maintenance is the time and expertise required to implement it successfully. Many manufacturers invest in condition monitoring technology but struggle to interpret the data effectively—resulting in frequent false alarms and little actionable insight.

Maintenance teams must also be trained to operate the equipment and analyze the data, which takes time and resources. Without proper training and support, data may be misinterpreted, causing teams to waste time on unnecessary tasks while critical issues go undetected.

Smarter hardware makes real-time insight possible

Predictive maintenance is only as effective as the data behind it. Thanks to advancements in IIoT, condition monitoring hardware is now more affordable, accurate, and easier to deploy than ever. Wireless sensors and modular nodes can now monitor vibration, pressure, oil quality, ultrasonic frequencies, and more—on both continuously running and intermittent equipment—without disrupting operations.

Software transforms raw data into action

But collecting data isn’t enough. That data must be processed, contextualized, and delivered in a way that helps teams act quickly and confidently. Today’s IIoT-enabled platforms do just that, turning condition monitoring insights into predictive guidance for maintenance teams, allowing manufacturers to allocate resources efficiently and stay ahead of equipment failure.

Moving beyond predictive maintenance to machine health optimization

A successful predictive maintenance program can help manufacturers avoid costly unplanned downtime by assessing and projecting asset health. This will contribute to the overall optimization of your plant, but fails to address the root of machine health issues.

An optimization-focused approach to machine health goes beyond basic diagnostics and alarming. Predictive maintenance will tell you when a machine is likely to need repair; machine health optimization will diagnose the damaging conditions and eliminate them. With the right asset intelligence and analytics at your disposal, you can solve asset problems permanently.
