Monitoring and diagnosting technical installation using purely mechanically activated signalling means.

摘要

The problem to be solved is to enable a person carrying out a walk across a plant to detect faults like an unwanted change of magnetic flux in a pump, which normally would not be sensible by human perception. Electrical machinery produces well defined magnetic flux. A flux sensitive coating may change color when the flux differs from the expected flux. Such discrepancies indicate the type of fault inside the machine, i.e. faulty rotors in electrical engines.
