pH control can be extremely challenging due to exceptional nonlinearity and sensitivity particularly when strong acids and strong bases are used. Advances in electrode design and signal selection can greatly help. The need to reduce oscillations from valve resolution limit and backlash can be addressed by valve design and use of a PID feature.
Just a quick post to let you know about two ISA web seminars being conducted by Control Talk blog's Greg McMillan. The first is on pH Control Solutions and will be February 13 from 2:00-3:30pm EST. You can find the webinar price here. These webinars are designed for...
I know from listening to some of Control Talk blog's Greg McMillan's presentations on pH control what a difficult control challenge this can be. Chemical Processing magazine has a great article, Forestall pHrustrations, by Emerson's Dave Joseph that shares ways to...
Controlling your process based on pH is usually a tricky matter. Control Talk blog's Greg McMillan and Emerson's Dave Joseph presented a short course, Adventures in pH Control, at last week's Emerson Exchange conference in Anaheim. It was a best in conference winner...
The ever-prolific Greg McMillan will be doing two February ISA webinars--one on temperature control and the other on pH control. The pH Control Solutions web seminar is on Wednesday, February 15 at 2-3:30pm EST. Greg's description is that it:...covers the root causes...
This Wednesday, November 9, 2011 at 2-3:30pm EST (19:00-20:30 UTC), ModelingAndControl.com's Greg McMillan will be a pH Control Solutions web seminar. Greg is also the author of the book, Advanced pH Measurement and Control, 3rd Edition. Here's the seminar abstract:...
In conjunction with the International Society of Automation (ISA), Greg McMillan will be conducting an online seminar on pH control solutions. It will be held on-line tomorrow, Wednesday, 2/16 from 1-2:30pm Central North American time (19:00-20:30 UTC). Here's a...
Greg McMillan will be conducting his 8th demo/seminar (a.k.a. deminar) tomorrow, August 25. The topic will be PID Control of Runaway Processes. It will be on-line and live across the internet at 10:00 am CDT / 15:00 UTC. Runaway processes are found in highly...
Let's close this week with a few important announcements. The first is that abstracts for the September 27 - October 1, 2010 Emerson Exchange meeting in San Antonio, Texas are due this coming Monday, March 15. In spite of my last-minute ways, I have two workshops...
ModelingAndControl.com's Greg McMillan was giving his pH Control Solutions webcast a dry run yesterday and it was an opportunity I didn't want miss. I always learn something when I'm around Greg. Greg will be conducting this live ISA web seminar on pH Control...
Update and bump: Greg's article is now live on the ISA.org InTech website. Below is the original Dec. 15, 2009 post. I received an advanced copy of an article ModelingAndControl.com's Greg McMillan has recently completed, Exceptional Opportunities for Smart Wireless...
ModelingAndControl.com's and Emerson technologist, Greg McMillan, will be presenting tomorrow at the ISA's Boston section. His presentation, Exceptional Process Control Opportunities describes how advances in measurements, valves, and control can make a dramatic...
