Wireless Personal Area Networks Book Adds IEC 62591 WirelessHART
After a two-week hiatus and lots of time away from "the grid", let's get things going here on the blog again. I was speaking with Emerson's Dr. José A. Gutierrez. He was kind enough to send me the third edition of the book, Low-Rate Wireless Personal Area Networks:...
Increased Span and Reduced Complexity in Process Automation
Pipeline magazine has an interesting article, The evolution of automation, which describes some of the ways automation technologies are changing plant environments. The article provides perspectives from several automation suppliers, including Emerson's Phillip Bond....
Avoiding Flameout and Shutdown in Burner Management Applications
Furnaces, fired heaters, boilers and other process units requiring burners to manage are common across many process industries such as refining, chemicals, petrochemicals, and power. Recognizing and reacting to flame instability is critical since a flameout condition...
Hydraulic Partial Stroke and Diagnostics on Emergency Shutdown Valves
I've discussed partial stroke testing (PST) as a diagnostic for the health of a valve in many posts over the years. These posts describe flow applications found in most process manufacturing facilities. But what about high-pressure and hydraulic applications including...
Clarifications on Process Fieldbuses
As 2010 was winding down, I did a post Digital Busses Team Up for Successful Results in which I referenced a book Catching the Process Fieldbus--An Introduction to Profibus for Process Automation. Over the holidays, I received an email from Emerson's Jonas Berge, whom...
Staying on Schedule through Diagnostic Detection
Emerson's David Sheppard, a certified functional safety expert, passed along a great story of a recent refinery incinerator startup. Over the course of a week, the incinerator was taken down so that the emergency shutdown system (ESD) and process control-related...
Mobile Accessibility to Valve Diagnostics
We must be having fun because this week has absolutely flown by. I had the chance to visit Innotech Austin yesterday afternoon. It's a conference for business technology innovations for IT and marketing professionals. The advances of social media and mobile...
Digitally Connected Variable Speed Drives
Whether controlling pumps, fans, blowers, conveyors, compressors, extruders, mixers, agitators, chippers, etc., AC variable speed drives can be found in most plants and mills. Emerson's Jonas Berge, whom you may recall from earlier digital communications-related...
Adding Wireless Level Measurement Diagnostics
A colleague pointed me to a recent ConnectingIndustry.com article, Taking wireless level data acquisition to HART. Emerson's Catrine Bengtsson shared her expertise for this article. Many plants have legacy control systems with analog input (AI) and analog output (AO)...
Technology Trends in Process Safety
Emerson's Mike Boudreaux shared a Control Engineering Asia article written by the renowned process safety expert, Paul Gruhn. The article, Providing Process Safety, analyzes some of the latest trends in safety instrumented systems (SIS) designs for the process...
