Condition Monitoring System for Industrial Drives
The detection of the resources condition and predictive maintenance in manufacturing requires sensors at critical points. Moving parts or bearings at production machines are monitored. Autarkic sensors allow a wireless installation also at positions where cable installation is difficult or impossible.
The developed condition monitoring system collects the required electrical energy from the vibrations of the drive. At very low vibrations from 0.07 g is enough power available to measure and send data in intervals less than 500 ms. Maximum distance using ZigBee or Bluetooth Low Energy (BLE) is up to 50 m.
