MEMS Accelerometers – Technology Review and Implications for CBM

Ed Spence
Ed Spence | Managing Director, The Machine Instrumentation Group

WEBINAR DESCRIPTION:

Wireless condition monitoring systems, also known as IIoT, promises easily deployed ‘continuous’ condition monitoring, with the potential to save some of that most precious commodity – your time. MEMS accelerometers have been instrumental in enabling the proliferation of these systems, but lingering concerns about MEMS performance add uncertainty to an already complex solution landscape.

In this session we will compare and contrast MEMS accelerometer technology with legacy PZT, discussing the implications for IIoT and CBM applications in general. We will demonstrate how MEMS performance improvements made over the last 5 years not only supports overalls trending but also enables bearing fault detection and diagnostics. With a better understanding of the underlying sensor technology strengths and limitations, we will also show how MEMS accelerometer performance positioning data suggests using caution when selecting wireless IIoT solutions for your assets.

Learning Takeaways:

  1. A better understanding of sensor technology performance and feature trade-offs, with implications for vibration measurement and asset condition monitoring.
  2. An analysis and comparison of accelerometer technology performance for commonly used monitoring and diagnostic algorithms, in particular velocity calculations and enveloping for bearing fault detection and diagnostics.
  3. Better understanding of the implications of MEMS accelerometer technology performance on IIoT solution positioning will help inform wireless system choices for the maintenance specialist.
  4. See how chip-scale MEMS sensors help enable embedded ‘digital’ sensors, supporting an emerging trend among OEMs.
