device to determine achslager heißgelaufener cars

摘要

The temperatures of a plurality of journal bearings or boxes on a passing car are monitored. An average temperature value for each side of the passing car is derived. Comparisons are then effected between the temperatures of the individual journal boxes disposed on a given side of the car and the derived average temperature value for the given side, and deviations above or below predetermined limits are utilized to signify the presence of an alarm condition.
