"Practical Predictive Maintenance", Polydrive 2/19, (PDF in German) This article compares MEMS and piezo-based sensors and shows analytically, that MEMS are less suited for low RPM applications, i.e. below 500 RPM. It also shows the risk of using RMS data only, like most low-cost IoT systems do, to determine the health state of a bearing. Finally, that information lost early in the machine vibration data acquisition chain cannot be recovered later, also not with AI (e.g. deep neural networks), while appropriate data pre-processing can deliver significant performance gains. 1232kB
