Leveraging the power of Profibus
Belgium is well-known for many of the good things in life: excellent cuisine, exquisite diamonds, sumptuous chocolates… and now the country can also boast about its superior networking solutions for infrastructure projects. So much becomes quite clear when talking to Kees Geldhof, who as Sales Engineer for AUMA in Belgium knows all about the benefits Profibus can bring....
Recent developments in process valve diagnostics
Most process valve manufacturers market 'smart' or 'intelligent' valves – typically a digital positioner plus a control valve. While this technology has been available for a long time for control valves, the situation in automated on/off valve development is totally different, argue Metso Automation Managers....
