Part 1, “How to Choose the Best MEMS Sensor for a Wireless Condition-Based Monitoring System—Part 1,” of this article series introduced the Voyager wireless CbM module as well as some key features to look out for when measuring vibration wirelessly with MEMS accelerometers. Part 2 will focus on describing common AC induction motor (ACIM) faults and will detail how to identify and diagnose specific fault types as well as the advantages triaxial MEMS accelerometers can offer over other vibration sensors.
