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.
