Reduced analysis time using ULB

As the response times governing cast iron production are growing ever shorter and at the same time more and more analyses need to be performed, reducing analysis time has become a major objective.

The question is: Does there exist any way to reduce the analysis time? The following shows an innovative technique, called Use of Light Breaks (ULB), a combination of a new styled spark stand and an intelligent integration system.

Given a spark frequency of 800 Hz, there is a time slot of 1.25 ms for each spark. However, a spark discharge and the resulting emission only takes about 0.25 ms, which means that signals only have to be actually measured and processed in a fifth of the integration time leaving the measuring system "idle” for four fifths of the time. ULB uses these "idle” times of the integration system to supply it with information from the second electrode.
