2.) How do Wireless Vibration Sensors work and transmit data?

Wireless vibration sensors are easy to install and work by converting mechanical vibrations into electrical signals using an accelerometer sensor. They are a central component to the best condition monitoring systems. The accelerometer measures acceleration, which is then processed through signal processing techniques to monitor vibration, such as RMS velocity, frequency domain and time domain. The sensor typically contains an integrated triaxial accelerometer for capturing vibrations in three orthogonal axes (x, y and z). Wireless communication protocols, such as LTE or Wi-Fi, are used for data transfer to a remote monitoring system, IIoT platforms, or cloud-based data analytics solution. Advanced analytics, machine learning and AI algorithms are then applied to the collected data to identify anomalies, predict equipment failures and provide actionable information for maintenance activities.

6.) What are the three (3) Crucial Parameters for Measuring Vibration and how well do Wireless Vibration Sensors do this?

The three (3) crucial parameters for measuring vibration are:

  • Displacement: The change in position of a vibrating component over time. Wireless vibration sensors, particularly those with high-resolution accelerometers, can accurately measure displacement by integrating the acceleration data twice to obtain displacement values. Displacement measurement focuses on the movement of the vibrating object and is suitable for large, slower-speed equipment.

  • Velocity: The rate of change of displacement, which provides insight into the severity of vibrations. Velocity measurements are appropriate for overall vibration monitoring and detecting issues like unbalance and misalignment. Wireless vibration sensors can measure velocity by integrating acceleration data once, offering accurate velocity measurements for condition monitoring purposes.

  • Acceleration: The rate of change of velocity, which helps identify high-frequency vibrations and resonances. Wireless vibration sensors excel in measuring acceleration, as accelerometers are inherently designed to capture this parameter directly. Acceleration measurement is useful for detecting high-frequency vibrations, such as those caused by bearing faults.

The best Wireless vibration sensors offer seamless data aggregation and perform well in measuring these parameters due to their advanced sensing technologies, such as MEMS accelerometers and their ability to capture data in three (3) orthogonal axes. This enables comprehensive and precise vibration monitoring, making them highly suitable for condition monitoring applications.
