Each of these sensors provides valuable information on a specific condition of the machine. These sensor data are fused, processed, and analyzed to build knowledge of the overall condition of the machine to make critical decisions on machine maintenance. Figure 2 illustrates some of the major applications of vibration monitoring in various markets. The breakdown in this figure highlights the importance of vibration data collection and analysis as part of a comprehensive solution for CM. Additional sensors can be used to collect data that will be fused together for a reliable and effective outcome. In the latest solutions offered in the industry,
Compared to the existing vibration sensor, the operating temperature range is extended to +105°C to meet the requirement of a demanding operating environment. The device can be operated either in a 3-axis mode or a single-axis mode which can be selected through dedicated registers. In the 3-axis mode, all three axes (x, y, z) are simultaneously active. In the single-axis mode only one axis is active. In single-axis mode, the resolution (noise density) of the active axis significantly improves.
Vibration monitoring applications
Vibration monitoring usually refers to the analysis of the vibration of a machine, equipment, or an appliance as part of a comprehensive application that is known as Condition Monitoring (CM) or Condition-based Monitoring (CbM). The vibration analysis plays a significant role in monitoring the health of the machine over time. However, in addition to the vibration data collection, a complete condition monitoring solution incorporates multiple sensors to collect vital equipment parameters including temperature, noise, pressure, smoke, and humidity.
