A Characterization System for Bearing Condition Monitoring Sensors, a Case Study with a Low Power Wireless Triaxial MEMS Based Sensor

In this work the authors present an ad hoc characterization system able to emulate vibration signatures related to various typical rotating machinery failures. In particular, the proposed system is aimed at testing distributed condition monitoring systems based on vibration measurements with MEMS accelerometers. The system, fully programmable, embeds a reference triaxial piezoelectric transducer, which provides reference measurements. The system has been applied, as a case study, to the test of a developed standalone low power triaxial MEMS based accelerometer node sensor for IoT applications for bearing faults diagnosis.
