Dear Control Engineering: I was looking at Back to Basics in the August issue about closed loop control. What is the main concern about overshoot? 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.

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. Honeywell will now offer its VersaFlow line, which will be Krohne magnetic, Coriolis, ultrasonic and vortex flowmeters distributed, supported, and serviced though Honeywell’s existing sales channels.
Measuring the amount of a substance, either liquid or solid, in a container is one of the most basic elements of process instrumentation and goes back to time immemorial. While we generally talk about measuring the level in a tank, in most situations the actual information desired is volume. Situations where a level measurement is desired for itself are far less common.
Most pressure sensors, electronic and mechanical, express accuracy as a percent of total range rather than the reading. Consequently, users like to size devices so they operate near their upper limit for greatest accuracy. Crystal Engineering has a new digital gage line that expresses accuracy as a percent of reading.
Magnetic flowmeters have many advantages. They’re compact, don’t restrict flow, economical, and generally easy to deal with. However, the conventional wisdom is that if you need very high precision, another technology (for instance, Coriolis) is required.

August 2, 2005 A good interlock design is one of the most crucial parts of any project as it provides protection of a company's most valuable assets--personnel, product and plant equipment. There are a few rules that we follow to make the interlock implementation easy to design, implement, and troubleshoot. Rule 1 – Interlocks are implemented at the control module layer between control modules. Since interlocking logic is designed to prevent unsafe equipment operation, it makes sense to implement them on the software that performs equipment control. Rule 2 – Device I/O points are monitored and manipulated exclusively through control modules.

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 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.

When I left the press conference room, everywhere I turned people appeared stunned, dazed, and you could hear them saying to one another and at the same time to no one the same thing being shouted and whispered across our nation and around the world, 'How could this happen? Who would do such a horrific thing? What could we do?' Throughout the convention center people continued placing one foot in front of the other, but it was apparent most were doing so without real purpose or direction.

Archive April in Control Engineering Welcome to the new millennium! If the last century saw the rise of process control as we know it now; what does the 21stcentury have in store for the process engineer? Is 'smaller, smarter, faster, and cheaper' going to be the mantra of the next 100 years? Probably not! How about 'Internet-enabled' and wireless technologies that apply to process control? Even though we have heard enough about that over the past 15 years, I feel sure that there is more to come. As long as companies 'have it their way' process-wise, process-specific control will never die. Total flexibility in system connectivity may be what the process engineer of the future is looking for.

Heartening news -expansion in a shrinking economy Spring House, Alpharetta, Phoenix Archive Can systems be too open? The terrorist attacks on the World Trade Center and the Pentagon can be attributed to many factors. To my way of thinking, the determination of the perpetrators to carry out these outrageous acts was helped by their ability to leverage the 'openness' of the United States' telecommunication infrastructure and industry's wholehearted participation in Internet-based commerce. As we have seen, allowing the wrong parties easy access to a wide range of information, including security information and availability of flight training manuals, along with wireless communication can have disastrous results. Control Engineering has written a bit about security lately, before and after Sept.
The major challenge, when electrical sensors are mounted on rotating structures, is getting the signals off the rotor. Direct wire connection is not possible.

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.
