Self-service analytics for non-data-scientists

Predicting and averting process and equipment problems takes tools to easily search, annotate and analyze existing historian data.

Analytics1

Though plant operations typically generate mind-boggling quantities of data—both structured and unstructured—plant engineers and operations personnel can only leverage a small percentage to make better process decisions. This is because most process data from plant systems is stored in online and off-line process historian archives, and process historian tools, although relatively simple to use, aren’t ideal for analyzing data or search queries. The archives are “write”-optimized and not “read/analytics”-optimized, so finding related historical events and building process context can be a time-consuming and laborious task. Improving process performance and…

Ask The Experts: Maximum rangeability of linear valves

A question about a pressure-independent balancing and control valve prompts an expert dissection of rangeability.

Q: I happened to read your article, “Rangeability of equal-percentage control valves” (Sept. 2013, p. 102). It was informative and crystal clear as to what rangeability for =% control valves means. This is the first time my mind was getting clear on this subject as I was reading sentence by…
