Process control
PID has been the mainstay of process control for more than 60 years, but technology and the ever-expanding role of plant engineers merit a new, closer look, advises Brian Tinham
PC versus PLC controls
PC-based automation, in various forms, has been around for decades, but PLCs and related systems remain as popular as ever. Brian Tinham examines the differences and establishes which approach makes most sense where
Instruments for control
Help is at hand for plant engineers facing up to the challenge of handling instrumentation and control. Brian Tinham reports on recent developments
So much more
Intelligent instruments have been with us for years, but although many more plants are installing them, they're still missing some important tricks, says Brian Tinham
Automatic for the people
REM probably didn't have plant automation on their minds when they released that album in 1992, but computing for the masses is reinvigorating control, writes Brian Tinham
Automation upgrade
With computing technology not known for standing still, it should come as no surprise that the control systems it underpins are getting cleverer and cheaper. Brian Tinham reports
Boiler breakthrough
While innovative energy- and emissions-saving add-ons are gaining in popularity for steam-raising plant, technology trialled on marine boilers is tackling water treatment. Brian Tinham examines the final piece of the jigsaw
