A bearing monitoring system is provided including one or more bearings (308,310,312,314) within a flow passage (306) and a working fluid passing over at least one surface of the bearings. A first thermocouple (316) is located in the flow passage upstream relative to the one or more bearings (308,310,312,314) and configured to measure a first temperature of the working fluid and a second thermocouple (318) is located in the flow passage downstream relative to the one or more bearings (308,310,312,314) and configured to measure a second temperature of the working fluid. The system further includes a control device (328) in communication with the first thermocouple (316) and the second thermocouple (318), and configured to compute a temperature gradient across the one or more bearings (308,310,312,314) from the first temperature and the second temperature, compare the temperature gradient against a known value, and if the temperature gradient exceeds the known value, the control device is configured to provide an alert. |
