SENSOR HUB COMPRISING A ROTATION ENCODER

摘要

A sensor hub for use in machine condition monitoring comprising a rotation sensor and a wireless communication module each operatively connected to a processing device. The rotation sensor and processing device are configured to receive power from a controller of the monitored machine. One or more additional sensors, which may be associated with the monitored machine or another machine, may also be operatively connected to the processing device. In an embodiment, the additional sensors may comprise any one or more of, or any combination of, an accelerometer, a temperature sensor, an acoustic sensor, an high frequency sensor, an humidity sensor, a barometric pressure sensor, a current sensor or a proximity sensor. The wireless communication module may support an ad hoc wireless communication protocol. Further, the wireless communication module may receive additional sensor data from one or more wireless sensor nodes associated with the monitored machine or another machine.
