The presentation will cover applications from the steel making industry which are normally difficult to monitor. In many cases the applications are slow rotating and have limited measuring windows. By using triggers and parallel processing you can achieve very good results, which will be presented using real cases from our customers! The presentation will cover how to set up the system, measurement strategy and interpretation of the results. The cases included come from the steel industry, but the experiences gained in these cases are highly applicable for other industries with challenging applications as well.
