As wireless communications technology continues to mature, applications have expanded from monitor only to monitor and control. In an earlier post, Event-Based Control in a Wireless World, I mentioned that presentations given by Emerson’s Terry Blevins and Willy...
IEC 62591
Controlling with Wireless Devices and MPC
Wireless standards for instrumentation go back to September 2007 when the HART Communications Foundation (now FieldComm Group) announced the official release of the HART 7 specification. This specification included the WirelessHART protocol. As we have chronicled in...
Avoiding the Impact of Steam Trap Failures
According to the U.S. Energy Information Administration, industrial manufacturers are larger energy consumers than the transportation, residential and commercial sectors. The industrial sector accounts for around 30 trillion BTUs of energy consumed annually....
Narrated Wireless and Event-Based Control Advancements Presentations
Yesterday, we highlighted presentations on wireless and event-based control technology advancements by Emerson's Terry Blevins, Willy Wojsznis and Mark Nixon. Terry and Willy presented these advancements at the First International Conference on Event-Based Control,...
Event-Based Control in a Wireless World
The First International Conference on Event-Based Control, Communication, and Signal Processing was held June 17-19, 2015 in Krakow, Poland and took place on the campus of AGH University of Science and Technology. Some of the world leaders in Event-Based Control...
Instrumenting for Increased Performance
Yesteryear, energy and water were relatively inexpensive, waste disposal carried little cost, emissions did not incur fines and people willing to work in harsh manufacturing plant and production facility environments were abundant. Today, energy and water costs are...
Internet of Things in Process Instrumentation and Automation
If you subscribe or follow many of the process instrumentation and automation publications, web sites, and/or social channels, you know that the Internet of Things (IoT), also known as the Industrial Internet of Things (IIoT) is a frequent topic of conversation....
Measurements to Improve Process Operations
Process measurement devices are installed where required to monitor, control, and safely shutdown the process. But often, additional measurements combined with the existing ones can help to improve several areas of process operations performance. I saw a chart from...
Reducing Relief Valve Emissions via Continuous Monitoring
There are many ways to manage pressure in production processes. A common way for handling over-pressure conditions is through the use of relief valves. Wikipedia defines a relief valve as: …a type of valve used to control or limit the pressure in a system or vessel...
Answering Common Questions about Wireless Instrumentation
As technologies advance through the adoption phases and into mainstream use, a common set of questions usually emerges. For example, as the IEC 62591 WirelessHART communications standard has moved from its introduction to the market in 2007 to present day, its use has...
Simplifying Hazardous Area Instrumentation Inspections
If your process includes hazardous locations, you can appreciate the extra care that must be taken with the wiring to instrumentation located in these areas. And ongoing testing of these transmitters and final control elements poses challenges as well. In a Control...
Foundation Fieldbus and WirelessHART for New Plant Construction
In an earlier post, Considerations for Wired versus Wireless Instrumentation, we provided some guidance on when to consider digital communications-enabled technologies such as Foundation fieldbus and when to consider wireless technologies such as WirelessHART....
