1. A system for monitoring a plurality of processes which are identical with respect to at least one process parameter, employing a plurality of sensors each connected for monitoring the at least one process parameter of a respective process, each sensor having a response and the sensors all having identical responses to the at least one process parameter, comprising:

  • sampling means connected to the sensors for deriving a succession of sensor response samples, each successive sample being associated with a respective sensor;

    monitoring means connected to said sampling means for receiving each sample in succession and for evaluating a predetermined characteristic of the sensor response represented by each sample to produce an evaluating result, said monitoring means defining a processing path having an input to which all samples are applied in series and having an output for providing an indication of the evaluating result for each sample; and

    diagnosing means connected for receiving and interpreting the indication of the evaluating result of each sample in order to provide an indication of status of each process.
