Roller bearing rotating component sensor system uses SAW and BAW sensor with responses transmitted through shared antenna as frequency separated narrow band signals

摘要

A roller bearing rotating component sensor system uses SAW and BAW sensors (1, 2) and transmits their responses (6, 7) by radio from the rotating system to a stationary receiver (12) as narrowband signals with large centre frequency (19, 20) separation (22) using a single antenna pair (5, 10). Independent claims are included for the procedures used by the system.
