MAINTENANCE INFORMATION DEVICE, CONDITION SENSOR FOR USE THEREIN AND METHOD WHICH CAN BE CARRIED OUT THEREWITH FOR ARRIVING AT A DECISION WHETHER OR NOT TO PERFORM SERVICING OR MAINTENANCE

摘要

A maintenance information device and method for performing condition-based maintenance by monitoring of the condition of a technical system using a sensor. In order to permit the use of relatively simple sensors with relatively simple evaluation logics, the method and device perform decision making processes on the basis of hyperordinal signals from imperfect hyperordinal condition sensors.
