In vibration analysis, the symbol g refers to the acceleration due to gravity, equal to 9.81 m/s². Expressing vibration levels in g makes it easier to compare and quantify oscillations in machines or structures.
The vibration range defines the interval of acceleration that a sensor can measure accurately. A low range, such as ±2 g, is ideal for subtle vibrations, while higher ranges, such as ±50 g or ±200 g, are needed for heavy machinery or shock events. It is important to keep in mind that the sensor noise increases with the vibration range. Choosing the right range is essential: if it is too low, the sensor saturates; if it is too high, small variations become less visible.
Micromega Dynamics provides sensors with ranges adapted to different use cases:
- The Recovib Tiny is a portable sensor available in three versions: ±2 g / ±6 g, ±15 g, and ±200 g. This flexibility makes it suitable for both delicate monitoring and high-impact industrial environments.
- The Recovib Feel is designed for practical use, to be connected directly on a PC or a smartphone, making it ideal for quick diagnostics, troubleshooting, and laboratory applications. It is available in ±2 g / ±6 g and ±15 g versions.
- The Recovib accelerometers are available in a wide range of options, from ±2  g to ±400  g, depending on the model. This broad flexibility makes it easy to select the optimal sensor range for any specific application.
By selecting the right g-range for each application, engineers ensure reliable data collection and avoid costly downtime or misinterpretation.
