Monitoring & metering
violation, the bar changes colour to yellow (warning) or red (alarm). Pictures and other components can be added to create user-friendly and intuitive information. Moreover, data can be easily exchanged with other systems via digital protocols (for example, Modbus, OPC UA, and MQTT). Another useful feature is the ability to export data of interest to a file for deeper analysis (see Figure 7). Another first-tier plot is the event/alert view (Figure 5). Operators can check currently active threshold violations or inspect changes in the past. Certainly, several filtering options are available to save operators’ time.
The trend plot presents the history of selected vibration parameters (rms and velocity rms) (Figure 6). Users can quickly check the nature of changes in time, such as volatility, rising trend, or correlation with other measurements. Sometimes, a deeper insight is necessary. Most often, we need to know what has caused an increased vibration level. The ultimate source is the investigation of the raw vibration signal. Vibration experts can analyse these signals with the waveform and spectrum plots.
This data comes from a sieve screener where eight sensors were used (four HF and four LF). Figure 8 presents one of the sensors mounted on the bearing.
The installation proved the functionality of sensors and their ability to monitor industrial assets even in harsh environments.
CONCLUSION
The AVS 1001HF and AVS 1003LF accelerometers represent significant

advancements in the field of industrial asset health monitoring. By integrating high frequency and low frequency vibration measurement capabilities with real-time data processing and transmission, these sensors provide a comprehensive solution for predictive maintenance. Their ease of integration, versatility, and high precision make them invaluable tools for enhancing productivity, reducing downtime, and optimising maintenance strategies in industrial environments.
By redefining condition monitoring, the AVS sensor family not only improves the operational efficiency of machinery but also sets a new standard for industrial asset health management. As industries continue to adopt smart technologies, advanced sensors like the AVS series will become increasingly pivotal in driving the next generation of industrial automation and maintenance forward.
