Condition monitoring plays a vital role in predictive maintenance. By continuously monitoring the health and performance of equipment, condition monitoring systems identify early warning signs of potential issues
The 21st-century industrial space is characterized by smart manufacturing, ever-growing efficiency, and data-driven decision-making. One of the key tools in achieving these is condition monitoring, a crucial aspect of predictive maintenance that enables businesses such as manufacturing plants and logistics companies to optimize their operations. In this blog post, we will go over the concept of condition monitoring, explore its various applications, and understand the benefits it offers. I will also touch on the role of the Industrial Internet of Things (IIoT) in revolutionizing the way condition monitoring is implemented, and highlight how IO-Link Wireless technology enables a huge leap forward in implementing and gaining the best results from these.
What is Condition Monitoring?
Condition monitoring is a systematic process that involves the continuous assessment of the health and performance of machines, equipment, and systems in an industrial setting. The primary objective of condition monitoring is to detect any deviations from normal operation and identify potential issues before they result in downtime or failures. This is a proactive method of maintenance that allows organizations to make educated decisions regarding repairs and replacements, optimizing various maintenance efforts and reducing overall operational costs.
At the core of any effective condition monitoring system are specialized condition monitoring solutions and condition monitoring equipment. These tools collect and analyze data from various sensors and devices strategically placed throughout the factory or production facility. Unlike in the past, when not all places were accessible with these sensors, IO-Link Wireless devices allow deployment even in the hardest-to-reach places, assuring full coverage of virtually any facility, and extracting data from it. This data provides valuable insights into the condition of equipment and enables predictive maintenance practices.
Predictive Maintenance & Condition Monitoring
Predictive maintenance is a maintenance strategy that aims to predict when equipment is likely to fail so that maintenance can be performed in due time to prevent the failure. It contrasts with traditional reactive maintenance, which involves fixing equipment after it has already failed, and preventive maintenance, which follows a fixed schedule regardless of the actual condition of the equipment. Both these methods result in high costs, either due to failure-derived downtime, or unnecessary replacement of costly components and equipment.
Condition monitoring plays a vital role in predictive maintenance. By continuously monitoring the health and performance of equipment, condition monitoring systems identify early warning signs of potential issues. Such signs may be abnormal vibrations, temperature fluctuations, clamping force, or changes in fluid flow patterns. These can be indicative of looming problems. The ability to detect these precautionary signs in real-time allows maintenance professionals to act on them before actual issues occur.
Benefits of Condition Monitoring
Implementing a robust condition monitoring system offers several key advantages for businesses in various industries. Here are a couple to serve as examples:
- Decreased Downtime
Downtime in industrial settings is a significant concern as it might result in lost production, missed deadlines, increased costs, and more. With the extended abilities of IO-Link Wireless, condition monitoring enables the decreasing of downtime by detecting issues early and allowing for planned maintenance, minimizing unexpected equipment and machine failures.
In a case study of a USA-based pharmaceutical manufacturer, the addition of wireless counting devices at designated areas along the production line provided real-time performance feedback. This led to faster cycling of machines, simplified workstation relocation, and reduced downtime, ultimately increasing productivity and reducing downtime-related losses. - Reduced Maintenance Costs
Traditional maintenance practices, whether reactive or preventive, can be costly. Reactive maintenance often involves emergency repairs and the replacement of expensive components. Preventive maintenance, while necessary, in most cases is inefficient and leads to unnecessary part replacements. Condition monitoring allows for more targeted and justified maintenance efforts, reducing the overall maintenance cost.
For example, in the airflow monitoring case study of a global bearing manufacturer, the implementation of an IO-Link Wireless solution for air leakage detection led to optimized maintenance. By detecting leakages in real-time, maintenance efforts became more efficient, eliminating time-consuming manual processes and reducing downtime-related expenses.
Types of Condition Monitoring
Condition monitoring can take two primary forms: offline condition monitoring and online condition monitoring. Each approach has its own characteristics and varies widely from the other, as we’ll see.
- Offline Condition Monitoring
Offline condition monitoring involves periodic inspections and data collection. During these inspections, maintenance personnel assess the condition of equipment and collect data that provides insights into the equipment’s health. This data can be analyzed to identify trends and anomalies.
Offline condition monitoring is suitable for equipment that can be taken offline for inspections without causing significant disruptions to operations. Traditionally, it is used for critical machinery and equipment that require in-depth assessments. However, it may not provide real-time insights into equipment performance. Additionally, this form was used while retrieving data from all parts of the machine was impossible, due to the difficult conditions involved in obtaining it. Yet, IO-Link Wireless proved to be competent even in the most complex and difficult conditions, such as in the case of CNC clamping. This required being able to gather the information from the CNC’s clamping jaws, while machining. As it was shown that this application became possible thanks to IO-Link Wireless, it put things in a new perspective throughout the industrial world. - Online Condition Monitoring
Online condition monitoring (which now proves to be available in most cases), on the other hand, involves continuous, real-time data collection and analysis. IO-Link Wireless connected sensors and monitoring equipment are installed on the equipment, and data is continuously transmitted to a central system for analysis. This real-time data allows for immediate detection of anomalies and potential issues.
Online condition monitoring is ideal, as it provides constant vigilance over the equipment’s condition. It is particularly useful for critical equipment where even short periods of downtime can be costly, making the ongoing machine condition monitoring essential.
Condition Monitoring and IIoT
The Industrial Internet of Things (IIoT) is a transformative force in the field of condition monitoring. It leverages the power of interconnected devices and sensors, to provide a comprehensive view of an industrial operation. IIoT enhances condition monitoring by enabling data collection from anywhere in the factory, without the limitations of traditional wired systems.
