Why is it a problem, and can’t a controller prevent it? An ideal controller should be able to move a process variable quickly to the desired setpoint without shooting past. Sometimes controllers will push the variable aggressively toward the setpoint knowing that it may go past, or overshoot the desired value and have to turn around and come back.

Among the thousands of varieties of potatoes, certain ones are prized for their ability to make specific products like potato chips or French fries. When a new breed is developed for specific characteristics, it can easily take five to seven years to generate enough seed to support commercial demand. Turck BL67 I/O system controls solenoid valves for CO2, humidity, and adding liquids used in the spray system.

Some ambient environments can be hard on instrumentation transmitters, causing more problems than difficult process conditions. If moisture gets inside the electronic elements of a transmitter, the signal can be corrupted or might fail altogether. Turck has introduced its new PT 510 pressure transmitter family, featuring a stainless steel diaphragm and fully welded construction that eliminates the need for an O-ring seal.

Tutorial: Rotameters (variable area) for compressed air flow metering

Measuring flow when the fluid is compressed air or other gas presents a different set of challenges than liquid, due to the fact that volume changes with pressure. To avoid that issue, air and gas flow is typically measured in SCFM (standard cubic feet per minute) rather than ACFM (actual cubic feet minute). Flowmeters that measure the mass of gas solve this issue easily, but they are generally expensive instruments.

How many more pressure sensor designs does the world need? I’ve asked myself this question recently in the context of news coming out from well known control system suppliers that are either partnering with specialized instrumentation vendors or buying them outright. You might think that companies like Rockwell, Honeywell, and Siemens might want to create their own product lines from scratch, but do they really need to? Partnering and acquisition prevents re-inventing the wheel, or in this case, re-inventing the flowmeter. The latest news of a new partnership is between Honeywell Process Solutions and Krohne for the former to offer the latter’s products under a private label agreement.

Hungarian tank-farm goes digital

Austin, TX — Emerson Process Management recently completed a $500,000 digital plant-architecture project at the Gedeon Richter Pharmaceutical Co.’s tank farm in Budapest, Hungary. The project is an extension to the company’s central tank farm installation, which supplies four plants with solvents. In planning the automation, Emerson determined that its PlantWeb had the technologies best suited to optimize start-up time and maximize operations and maintenance efficiencies—a key element was the company’s Fisher Design-GX control valve. Work on the expansion started in October 2004 and included: a Delta V digital automation system; AMS Suite: Intelligent Device Manager software; HART-based communications; 59 GX control-valves, with Fisher Fieldvue-DVC6000 digital valve-controllers; 52 Rosemount-2088 pressure transmitters; and services that included engineering and installation. Designed in accordance with European standards, GX is a globe-style valve system that can control a wide range of process liquids, gases and vapors.

Open-loop control continues to find relevance in industrial, military, and aerospace applications despite its simplistic and less-than-perfect performance as a control mechanism. But what is open-loop control? Examples can be found in the night-light that comes on when the sky darkens or the oil vapor valve in a military jet engine that modulates with altitude.

AutomationDirect presents – Motor efficiency improvement

A custom advertising newsletter from Control Engineering & AutomationDirect| September 29, 2004 Motor efficiency improvement Making sure the motors operating on your plant floor or in end products are extremely dependable is the name of the game for mechanical engineers. Here's a look at why the connection of variable frequency drives is often the optimal choice for motor operation enhancement. To some degree, a motor operates more efficiently—certainly with greater dependability—when teamed with a variable frequency drive (VFD). One of the primary reasons for this is that motors operated by VFDs are not adversely affected by "inrush" current, as are their line-started counterparts. An "inrush" is a high current, typically six to seven times full load, which causes more stress on the end turns of the motor than the program-controlled ramp-up of a VFD.

Inside Process Flint Ink Steps Its Way to Success

Inside Process Flint Ink Steps Its Way to Success By adopting a pay-as-you-go automation philosophy, Flint Ink’s New Albany production center is about to become an integrated, paperless operation. Dave Harrold, CONTROL ENGINEERING Committed to increasing productivity, lowering costs, and reducing product variability at its New Albany, Indiana facility, Flint Ink began an automation journey that, like most journeys, included a number of unexpected bumps, twists, turns, and thrills along the way. Though the journey isn’t complete, all the participants are positive the hardest parts are behind them and the rewards have already made the trip worth the effort. Ink is not just ink Most ink is used in high-speed printing of newspapers and magazines, but just looking at it, ink doesn’t seem that complex.Formulas of inks differ widely to suit the variety of printing presses, methods of drying, varia-tions in print substrates, and end-user considerations. Because press type, drying methods, and paper stock offer few adjustable parameters, Flint Ink employs more than 500 PhDs, chemists, physicists, chemical engineers, ink formulators, and technical service representatives to work with customers to create just the right ink formulation for an application. From a control viewpoint, ink manufacturing isn’t nearly as complex as other batch processes, such as biotechnology. Yes, there are many discrete valves and mass flowmeters; some temperature, level, and speed controls; and a definite need for coordinated unit transfers, but the basic process is relatively simple.

This approach offers the advantage of buying from an existing manufacturer and not having to learn a new technology. However, suppose it's a new flowmeter application? What are the important criteria in choosing one flowmeter ...

Analyze This!

Continuous process manufacturing cannot exist on pressure, temperature, level, and flow measurements alone. In fact, very few areas of industrial operations exist where chemical composition variables do not need to be measured as part of the control process. In many areas, laboratory measurements still prevail.

Quick tip for speedier prox switch setups

C lose examination of sensor housing specs can help speed setup of tubular inductive proxes. A typical prox sensor housing spec reads 'M12 x 1.' The '12' indicates housing diameter (12mm), the 'M' indicates that the housing is threaded, and the 'x 1' means the thread pitch is 1mm. The last spec means that one sensor revolution creates 1mm of linear travel, which is very handy setup information when installing both shielded and unshielded sensors. Let's say the maximum sensing distance of the sensor is 4mm.

Applying Flow Conditioning

Process industries are required to measure flow accurately to meet both plant operation and cost accounting objectives. However, these objectives can be difficult to achieve because the accuracy of many flow meter technologies can be adversely affected by flow disturbances. These are often caused by inadequate straight runs of pipe or other disturbances upstream of the flowmeter's location.

Analog Transmitters Lead the Pack

When working on a PC, you've probably come to appreciate that antivirus protection icon at the bottom right-hand corner of your screen. As that software works to protect your work and your investment, so do process variable transmitters (PVTs) work to protect your in-plant work and investment. In fact, they may be the savior of every engineer who uses them.
