Temperature Measurement Installation Best Practices

Let’s conclude our Temperature Insights educational video blog post series with a look at Temperature Measurement Installation Best Practices. In this 4:42 YouTube video, Emerson’s team managing the Rosemount temperature sensors and transmitters explains how to gain accuracy and reliability in temperature measurement through proper installation techniques.

For Foundation Fieldbus Segment Design-Use Typicals Approach

Last week I highlighted an updated tool for designing Foundation fieldbus segments. Emerson’s Jonas Berge left a great comment with links for additional resources to which I wanted to bring visibility in this post. I’ve also inserted some hyperlinks where you can find additional information.

In my personal opinion this software is a great design tool but should be used correctly because the usability of fieldbus has improved also with respect to easier design. Fieldbus has become more powerful and therefore more flexible than it was years ago. Some history: in the early days of fieldbus, the fieldbus power supplies (“conditioners”) had a low output voltage (less than 24 V) and, in particular, intrinsic safety barriers used the ‘entity’ concept which severely limited voltage (11 V) and current (60 mA). Back then fieldbus segments had to be designed one by one, each bus segment calculated to cram in as many devices as the low voltage would permit based on the exact cable length and current draw of each device. Due to the limitations, that design principle was required. Since a large plant has many bus segments, the tool came in very handy to make all these calculations. Because fieldbus power supplies and safety barriers have evolved, that same design principle need not be applied. It is now much simpler. Continue Reading

Renewables and the Cost of Electricity in the EU

Germany has established itself as a leader in developing renewable power and has accelerated its efforts since the Fukushima nuclear accident in 2011.

To date, the share of renewable generation in Germany exceeds 25 percent.

To spur development, the country has in place a tariff system that provides incentive to build solar and wind. This system did just that, but it also raised the prices of German electricity to some of the highest in the world. Not only is the cost high, but the renewable surcharge per kilowatt hour grew considerably. Continue Reading

What to Do When the DeltaV Calc Block Is Not Enough

The process control domain continues to get more and more sophisticated as Emerson’s customers use process models and increasingly sophisticated calculations to optimize process control. Once case in point is an example I saw at last year’s Emerson Exchange conference where one of Emerson’s customers presented how they using advanced mathematics to detect the peak UV absorbance during chromatography elution. While this seems like a simple enough, this required solving partial differential equations, Linear algebra, and vector based mathematics.

Solving Partial Differential Equations

The mathematical function used to represent the chromatography peak was the Extreme Value Function which was referenced for this purpose by the Journal of Chromatography. This function is easy to solve using applications such as Matlab. But very difficult to solve using DeltaV controller modules and Calc Blocks! Continue Reading

Foundation Fieldbus Segment Design Tool

If you use Foundation fieldbus technology with your smart instrumentation in your plant or perhaps may in the future, I want to share that an updated Segment Design Tool is now available for you to download.

This tool is specifically designed to verify physical and electrical parameters of a Foundation™ fieldbus (FF) segment, operating under Emerson Process Management host system interfaces, such as DeltaV distributed control systems, AMS Device Manager software, and Ovation expert control systems.

This release has added support for the Windows 7 operating system, improved FF devices library management and support for both Simplex and Redundant H1 cards of DeltaV S series with Integrated Power Supply, and numerous field devices from a variety of manufacturers listed on Device Install kit of website of Emerson. The Segment Design Tool is compatible with the Windows XP / Windows 7 operating systems.

Once you download and install the tool, you’ll want to register it to get full access to all the embedded features within the tool. Also, here is an email link to the support team should you experience any issues.

To connect and interact with other Foundation fieldbus host system users, join the DeltaV, Ovation and/or Asset Optimization, Maintenance & Reliability tracks of the Emerson Exchange 365 community.
