Wireless Sensor for Real-Time Bearing Condition Monitoring
Researchers at Purdue University have developed a unique wireless sensor capable of sensing both temperature and vibration of a bearing cage simultaneously using inductive coupling. The system uses only a temperature-sensitive capacitor, a sensor coil, and an interrogator coil. Both the temperature and vibration measurements are then detected through reactions between the bearing and the coils. The sensor was able to accurately detect temperatures up to 90 degrees Celsius and several vibration frequencies at various shaft speeds.
