What is condition monitoring?

Condition monitoring is a predictive maintenance method that relies on real-time data collection to monitor the health of equipment and systems. Its core objective is to detect problems and anomalies before they escalate into major breakdowns. Consequently, it reduces unexpected downtime and extends the lifespan of valuable assets.

When organizations adopt condition monitoring techniques, they regularly collect data from sensors and high-tech devices installed on the assets they want to track. These sensors monitor various parameters such as vibration, temperature, pressure, and sound. Subsequently, maintenance teams delve into this data, employing specialized techniques and software tools to analyze and interpret it effectively.

How does condition monitoring work?

Condition monitoring within facilities management involves gathering and analyzing data from a range of sensors and monitoring devices. This predictive maintenance method enables facility managers to anticipate and address potential issues by continuously evaluating the health and performance of critical systems and equipment.

Outlined below are the typical steps involved in the process of condition monitoring:

1. Data collection

Sensors, meters, and other monitoring devices are installed throughout the facility to gather data on key parameters such as temperature, pressure, vibration, electrical currents, and more. These sensors may be directly integrated into the equipment or connected to a central monitoring system.

2. Data analysis

The collected data is analyzed using advanced algorithms and software tools. This analysis aims to identify patterns, trends, anomalies, or deviations from normal operating conditions that could indicate potential issues or failures.

3. Fault detection

By continuously monitoring equipment performance, condition monitoring systems can detect early signs of deterioration, wear and tear, or impending failures. This allows facility managers to take proactive measures before the problem escalates into a costly breakdown.

4. Predictive maintenance

One of the key benefits of condition monitoring is its ability to enable predictive maintenance strategies. By analyzing equipment data and performance trends, facility managers can predict when maintenance or repairs are likely to be needed, allowing them to schedule maintenance activities during planned downtime, thereby minimizing disruption to operations.

5. Risk mitigation

Condition monitoring helps in mitigating risks associated with equipment failures, downtime, safety hazards, and environmental impacts. By identifying potential issues early on, facility managers can take corrective actions to prevent accidents, minimize downtime, and ensure compliance with regulations.

What are the benefits of condition monitoring?

Even with routine maintenance, mechanical failures can still occur. Condition monitoring techniques help to take control, proactively preventing breakdowns. It operates seamlessly, conserving resources by reducing unnecessary maintenance, secondary damages, and lost productivity. Integrating condition monitoring into routine maintenance programs enhances machine functionality and boosts long-term productivity.

There are several key benefits of condition monitoring for managing the health of machinery:

1. Monitor assets in real-time

Real-time asset monitoring involves continuously collecting data from sensors and equipment installed on critical assets. By doing so, organizations gain immediate insights into asset health, performance, and potential issues.

Benefits:

  • Early detection: Real-time monitoring allows prompt identification of anomalies, faults, or deviations from normal operations. This enables proactive intervention before problems escalate.
  • Improved decision-making: Access to real-time data enables maintenance teams to make informed decisions, allocate resources efficiently, and prioritize actions based on actual asset conditions.
2. Minimize maintenance costs

Condition monitoring helps minimize maintenance expenses by optimizing resource allocation and reducing unnecessary interventions.

Benefits:

  • Predictive maintenance method: Instead of following fixed schedules, maintenance activities are triggered based on actual asset conditions. This prevents over-maintenance and reduces costs.
  • Avoiding unnecessary repairs: Real-time data ensures that maintenance efforts are focused on assets that truly need attention, avoiding unnecessary repairs or replacements.
3. Extend asset life

Regular monitoring and timely interventions contribute to asset longevity.

Benefits:

  • Preventing premature failures: Addressing issues early prevents wear and tear, prolonging the life of critical components.
  • Optimized usage: By understanding asset behavior, organizations can optimize usage patterns, reducing stress on equipment and extending its operational life.
4. Prioritize maintenance activities

Condition monitoring provides insights to prioritize maintenance tasks effectively.

Benefits:

  • Risk-based approach: Assets with higher risk profiles receive more attention. Critical systems are monitored closely, while less critical ones follow a less intensive maintenance schedule.
  • Resource allocation: Maintenance efforts are allocated based on asset importance, safety implications, and operational impact.
5. Reduce unplanned downtime

Unplanned downtime disrupts operations and affects productivity.

Benefits:

  • Early warnings: Real-time monitoring alerts maintenance teams to potential failures, allowing them to take preventive measures.
  • Scheduled maintenance: By addressing issues proactively, organizations can schedule maintenance during planned downtime, minimizing disruptions.

Condition-based monitoring techniques

Condition monitoring begins with a basic inspection, where small changes such as abnormal temperatures or pressures, strange sounds, excessive vibrations, or unusual odors serve as early indicator of potential problems. However, condition monitoring methods range from the simplest checks to advanced technology.
