American economist to address conference

Economist Alan Beaulieu predicts the U.S. economy will recover, despite economic turbulence in the European Union, political unrest in the Middle East, and rising fuel prices and pre-election jitters at home.

“Escalating oil prices could indeed push consumers and businesses into a recession, but not this time,” Beaulieu predicts. “Should the worst case scenario happen and Iran stop the flow of oil exports, other regions are likely to pick up the slack in terms of supply. Oil prices will go up, but probably not to the point of bringing on a recession either here or in Europe.”

A well-known trend analyst and the president of the Institute for Trend Research, Beaulieu will dispel listeners’ uncertainty about the worldwide economy and set forth strategy and tactics for recovery in the keynote address at the 2012 Executive Conference of the Control System Integrators Association (CSIA) 25/28 April.

The conference will bring together more than 400 control system integrators and vendor partners from the United States, Canada, Latin America and abroad at the Talking Stick Resort, Scottsdale (AZ US). Program details, registration information and hotel reservations are on the website.

Control system integrators design sophisticated control systems for manufacturing and industrial facilities. Using their knowledge of engineering, information technology and business, control system integrators help their clients integrate equipment and automate processes to reduce cost, increase production, use less energy and lower environmental impact.

E & I project in South Africa

Automation and power equipment will help increase mill efficiency and lower fuel consumption

ABB has been awarded a large Electrification and Instrumentation (E&I) and Distributed Control System (DCS) order by Sappi Southern Africa.

ABB will engineer, procure and supply equipment for Sappi’s Ngodwana mill in Nelspruit (ZA). This scope forms part of Sappi’s Project Go Cell, which entails the expansion of the current mill for the production of chemical cellulose. This order follows ABB’s successful implementation of Sappi Saiccor’s Amakhulu project in 2007.

Among the products to be supplied are Medium Voltage switchgear, Low Voltage MCCs incorporating intelligent motor controls, Profibus intelligent instrumentation, Variable Speed Drives and ABB’s state of the art 800xA control system. These products will support the mill’s goals of increased efficiency and lower energy consumption.

Due to the size and complexity of the project and to meet Sappi’s project deadline, ABB will have an international team of Pulp and Paper composite plant experts from South Africa, Finland and Singapore work on this project. The project team will ensure the seamless installation and completion of the electrification and automation equipment in Sappi’s required timeframes (plant production is expected to begin in 2013).

Transducers for sea floor valve control are built for high reliability

Transducers embodied in valves used for controlling oil flow in undersea pipelines have been developed by RDP Electronics to operate with high accuracy and high reliability.

RDP’s LVDTs are supplied to several valve manufacturers for use with valves controlling the flow of oil from pipe networks on the bottom of the sea, close to the well head. The transducers are usually sealed within the valve and are required to withstand very high pressures of up to 5000 psi. One construction option is to ventilate the transducer, allowing the oil to flow freely through the transducer, providing fluids are non-conductive and non-corrosive.

Ventilated LVDT transducers are used in conjunction with sealed amplifiers and are also immersed in the oil. Alternatively sealed transducers can be provided that are manufactured with a fully welded construction. In all cases the transducers are subjected to a very high level of production testing, including pressure testing in both water and in helium, shock and vibration testing and repeated temperature cycles at many points in the production process to ensure minimal failure rates in the field. RDP’s onerous testing regime has achieved extremely high reliability rates for these LVDTs, with less than 1 failure in 2000 units per year.

Reliable level detection with innovative frequency sweep technology

Baumer’s LBFS level switch is a reliable alternative to widely used vibratory level switches. The LBFS sensor can also detect the levels of viscous or dry materials and can be fitted on tanks or pipes in any desired position. The sensor is insensitive to flow, turbulence, bubbles or foaming, and suspended solids. The compact, smooth sensor head resists media adhesion, even with sticky media. The sensor’s short response time enables rapid fill level detection and accurate, reliable fill level compliance.

The level switch is able to detect media levels in tanks, vessels and pipes. It can also be used for overflow prevention, pump protection against dry running, and media separation with oil/water mixtures. It is suitable for an extremely broad range of application areas, including domestic water, wastewater, HVAC filters, hydraulic systems, oil and gas, bio-energy, wood pellets, grain mills, rail transport and pump systems.

The sensor is housed in a compact, extremely sturdy and corrosion resistant stainless steel enclosure. It can be installed easily and using Teflon tape sealing. Convenient configuration is facilitated by the PC-based FlexProgrammer 9701. Thanks to a short response time of just 0.2 s, the level switch operates very reliably even with fast filling processes. The device has a wide rated operating temperature range of -40 to +115 °C.

The LBFS operates on the frequency sweep principle using a high-frequency signal emitted by the sensor, which experiences a phase shift in the sensed medium. When this sensor encounters a medium having a dielectric constant outside the defined range, an electronic signal is triggered. The sensor’s high sensitivity over a large measuring range for dielectric constants from 1.5 to over 100 enables limit detection with all types of powders, granulates and liquids. Even difficult substances, such as polyamide granulates and paper, can be detected reliably. This technology has additional decisive advantages over other measuring methods, such as vibrating fork sensors, ultrasonic sensors and optical sensors: it has no moving parts and is insensitive to the effects of variations in conductivity, temperature and pressure. The sensor is additionally suitable for all types of applications that previously required different types of devices.

Tested but untouched..

TorqSense, a non-contact digital torque monitoring system that could guarantee an infinite lightness of touch has proven to be the only way to test the seals of super high performance vacuum systems. This is a sensor system developed by Sensor Technologies.

The ultimate fields of precision manufacture, such as electronics, biophysics and thin film deposition where tolerances are measured in atoms, are often conducted in hard vacuum to remove airborne contaminants and avoid the performance reducing effects of tiny air movements.

However the vast majority of vacuum chamber designs require seals for rotary drive shafts (called rotary feedthroughs) and ‘feedthroughs’ for the passage of materials, components, tools and finished products. In high vacuum applications conventional seals are unlikely to be able to achieve the performance specifications required, so magnetic fluid seals are used.

A ferrofluid is a stable colloidal suspension of sub-domain magnetic nano particles in a liquid carrier. The particles, which have an average size of about 100Å (10 nm), are coated with a stabilising dispersing agent (surfactant), which prevents particle agglomeration even when a strong magnetic field gradient is applied to the ferrofluid.

With over thirty years of experience producing seals for the world's most demanding applications, Ferrotec of Woolwich (GB) is able to optimise ferrofluid materials for the most extreme performance requirements and incorporate them into bespoke vacuum system designs.

“About half of our work is to bespoke design,” says Jeff Lewcock of Ferrotec, “and we have to test every seal to the nth degree to meet out customers specifications. To test the feedthrough it is mounted onto a vacuum chamber that is connected to a helium leak detector. Helium is then spayed onto the feedthrough and the leak rate observed during static and dynamic running."

As part of the test the starting and running torque of the seal are measured and the power loss through the seal is calculated. These readings allow Ferrotec to troubleshoot the individual seal, analyse the design’s performance and add to Ferrotec’s knowledge base.

“With the sort of tolerances we work to we needed a torque sensor that didn’t add any extra drag to the whole seal mechanism, so we were delighted to discover Sensor Technology’s non-contact TorqSense,” says Jeff.

Inside TorqSense torque sensors two tiny piezo frequency resonating combs are fixed to the shaft and supplied with power via a radio signal. The combs ‘opens up’ as torque is applied to the shaft changing their resonating frequency. Thus, the resonant frequency of the returning radio signal is an indication of the torque within the seal.

A wireless radio frequency non contact radio frequency coupling is used to supply power and interrogate the combs. Because it is non-contact the TorqSense torque sensor exerts no drag on the test piece whatsoever, and as it is fundamentally a digital system it has a broader signal bandwidth than other analogue based technologies and electromagnetic interference is eliminated making it an ideal solution for Ferrotec’s needs.

Transducers for paper!

Transducers developed for paper production measurement

RDP Electronics has developed transducers designed to withstand the corrosive environment encountered in pulp and paper manufacturing processes.

Their transducers have been widely used in paper machines for many years and the company has developed a special transducer version in response to the requirement for resistance to the effects of paper stock. Particularly around the slice indication application, where LVDTs measure the gap through which the paper pulp is extruded on to the webbing, there is a high tendency of the transducer to be splashed and wetted with paper stock which contains corrosive chemicals. These chemicals are corrosive, even to some steels so transducers for this application are designed to provide protection against the chemicals in the paper stock, as well as protection against the cleaning functions that are undertaken using high pressure hoses. The transducers typically have a built in 4-20mA amplifier for easy interface into the paper machine control system.

RIO embedded devices with multifunction I/O for custom applications!

National Instruments has four new NI Single-Board RIO board-level embedded devices featuring a real-time processor, Spartan-6 field-programmable gate array (FPGA), analog and digital I/O and more built-in peripherals for custom embedded control and monitoring applications. The new devices provide engineers with off-the-shelf FPGA and real-time processor technology through NI LabVIEW while maintaining the custom I/O often required for high-volume deployments through the option of a RIO Mezzanine Card connector. The connector provides direct access to FPGA digital input/output (DIO) lines and certain processor-specific functions for mating custom daughter cards. NI Single-Board RIO alleviates the effort of designing an entire system from scratch so designers can focus on the custom parts of their applications, such as the I/O. 

With the new devices, engineers can achieve the shorter time to market of an off-the-shelf system along with the I/O customization offered by in-house designs, providing the best of both worlds. The devices also feature built-in analog I/O so engineers can take advantage of the company’s industry-leading analog expertise in addition to their application-specific circuitry. The devices’ low-cost, small form factor; built-in I/O; real-time processor; and FPGA provide an ideal platform for embedded monitoring and control applications in industries such as medical and energy.

Planning & verifying switchgear

Rittal’s latest Power Engineering planning software v6.0 provide comprehensive support in planning and verifying standardised Ri4Power switchgear, as required by the new IEC 61439-1/-2 standard for low voltage switchgear. Main features of the new standard include extensive verification of the design of switchgear created by original switchgear manufacturer, as well as exact details of the rated currents of switching devices. The new standard offers major benefits, both for the manufacturers of switchgear, as well as for customers and users.

With the extension of design certifications, features are defined that increase the quality of low-voltage switchgear. Their interfaces to external peripherals are specified and defined in more detail. Design of low-voltage becomes easier and safer because the influence of the enclosure and protection category on the switching equipment is given greater consideration than before.

Using Rittal Power Engineering a suitable switching device can be selected as early as the low-voltage switchgear preparation stage that bears the current needed by the circuit. The protection category and the mounting location within the unit are also taken into account. Similarly, the software provides the appropriate design verification at the push of a button. The engineering tool offers check-lists with which the switchgear manufacturer can check all the requirements that have to be considered during the planning and performance of the switchgear.

Loop powered indicator is explosion proof

New loop powered indicator for explosion proof applications

Yokogawa has announced the the release of another high quality and well engineered product, the MLX loop powered indicator. The MLX is the latest addition to Yokogawa’s family of loop powered indicators operating from a 4-20 mA DC input. This model incorporates the LCD from the Yokogawa EJX pressure transmitter into a NEMA 4X aluminum housing. The MLX currently meets Factory Mutual or FM Explosion Proof requirements and will meet INMETRO, CSA, ATEX, IEC and Russian GOST in the near future.

Typical applications for FM approved loop powered indicators are located in potentially hazardous environments. They have been specified mostly by the chemical industry for the past 25-30 years. However, these indicators can be used in many other industries where a rugged, weatherproof enclosure is needed. Loop powered indicators provide an additional view of the measured value between a field instrument and the control room. This local indication of flow, pressure, liquid level or temperature can also be an invaluable aid during maintenance or when troubleshooting a malfunction.

The MLX contains a 6 digit numerical display with a range of +/- 999999, a 6 digit alphanumeric display for engineering units and a 20 segment bar graph indicating 0 to 100% of full scale. Most LCDs used in loop powered indicators are typically 3.5, 4.5 or 5 digit displays. With a 6 digit numerical display, additional resolution is provided to the end user. The numerical and alphanumeric displays are configurable to show the desired number and engineering units.

Another MLX feature is root extraction to aid in flow measurement. The MLX will extract the square root from the 4-20 mA signal sent by the differential flow/pressure transmitter displaying the actual flow reading.
Like Yokogawa’s MLA, MLD, and MLD1 loop powered indicators, the MLX shares the following characteristics:
• 4-20 mA DC input
• Same NEMA 4X aluminum housing
• Horizontal or Vertical Mount on 2” Pipe
• FM approval
• Epoxy Resin or Polyurethane-Epoxy Paint Options
• Calibration Range and Scale Option
• Stainless Steel Tag Option

Ranges of airflow sensors increased!

High sensitivity at very low flows allow detection of the low pressure drops that often occur in medical applications.

Honeywell has added new flow ranges to its Zephyr™ Analog and Digital Airflow Sensor portfolio to provide high sensitivity at very low flows – making the sensor portfolio ideal for use in a variety of medical equipment and industrial applications.

The company has added four standard flow ranges between ±50 SCCM and ±750 SCCM to its existing flow range of ±200 SCCM. In addition to the flow ranges, a new port/housing style, the short port fastener mount, has also been added to the portfolio. The extended flow ranges give the Honeywell Zephyr™ the ability to detect low-pressure drops that often occur in medical applications and which can impact patient comfort, and can reduce noise and system wear on components, such as motors and pumps. In industrial applications, lower flow range detection can optimize performance in gas leak detection and clogged HVAC air filter detection.

“With the addition of the new airflow ranges, Honeywell provides its customers with more options to integrate the sensor into their application,” said AJ Smith, director of global product marketing for Honeywell Sensing and Control. “Customers will also benefit from the portfolio’s industry-leading accuracy and the ability to customize the sensor to meet their specific application needs.”

Customers who have already designed a bypass that extends the flow range above the normal range of the existing airflow sensor can now use the Honeywell Zephyr™ airflow sensor to optimize overall performance and reduce manufacturing costs.

Additional industry-leading features of the Honeywell Zephyr™ airflow portfolio include:

• Total Error Band as low as ±2.25 %FSS (full scale span) allow for very accurate airflow measurement

• Stability reduces errors due to thermal effects and null shift, providing accurate readings over time and often eliminating system calibration after PC board mount

Digital process terminal and line attendant

Aegis Software is to unveil a unique touch-screen device to ensure a controlled process and provide a powerful and yet simplified interface to factory information systems. Visitors to the Aegis booth at APEX (San Diego CA USA, 28 Feb-1 Apl 2012) will see first-hand how inForce monitors and controls the process, informs operators, saves energy and workspace, and reduces the infrastructure cost and complexity of best-in-class factories.

inForce is a multi-function bridge connecting your Aegis software system to operators and equipment throughout the factory. It provides a turn-key touch screen operator interface, an intuitive user information center, a scanning and tracking terminal, and the means for an Aegis MOS system to physically control the process.

“inForce radically improves the simplicity, economics, and functionality of a factory information solution. Implementing a factory information system normally involves PC hardware costs, IT maintenance costs for those PCs, high energy consumption, and sizable workstation real estate. Our vision was to provide scanning on lines in an assured manner and to provide and interactive operator terminal without having to place PCs at every single process station”, commented Jason Spera, Aegis CEO. “inForce does this by providing a plug-and-play, auto-maintaining, compact and simple interface that provides many of the features where normally a PC would be required. As well, it functions as a bridge for the MOS system to physically reach into the process and control conveyors. ”

The inForce full-colour touchscreen display delivers operators useful alarm and production status information without the need for a PC. Wherever an interface to an Aegis MOS system is required, its compact console can be mounted using standardized VESA arms, under shelves, or even on a tabletop like a self-standing picture frame. The interface also supports audio to further enhance operator information. inForce enables your Aegis system to physically control conveyor flow, acquire barcode scans, and ensure accurate and complete WIP data transactions even on conveyorized lines. An optional light tower is available to extend the range of inForce’s visibility to operators where required.

Capabilities and Options
Operator Interface, Barcode Tracking & Conveyor Control
Ensure every unit is scanned accurately on a conveyorized line, stop the line automatically when Aegis alarm conditions occur, and inform operators about line status at each station. In this configuration, the inForce console is mounted where visible at the conveyor point of use, connected to your scanners and the Interface Module. The interface module is placed on the floor and electronically connected to your conveyors via SMEMA, the factory Ethernet, and power.

Conveyor WIP Monitoring Only
Track the counts of units moving through conveyorized lines for WIP quantity monitoring without specific barcode identifier capture. In this configuration, only the inForce Digital Line Attendant Module is integrated to power, the conveyor, and Ethernet. (Coming soon via automatic firmware update)

Workstation MES Interface
Most processes include workstations that require only unit scanning and ‘pass/fail’ entry at a given point. More advanced functions requiring a full PC user interface are not required at these stations. For such situations, inForce eliminates the need for a costly, bulky PC and provides the operator a simplified and compact interface at their workstation. (Coming soon via automatic firmware update)

Light Tower Option
Where broader visibility to the status of an inForce-controlled station is required, an optional light tower integrates directly to the inForce Line Attendant Module.

Unique Benefits
Interactive and Informative
With a full-color touchscreen display that responds even to gloved hands or a stylus, inForce does not simply control the process, it informs the operator as to status and the ‘why’ behind the control decisions enforces. An interactive, informative solution for your operators to keep lines running efficiently.
Vivid LED alarm lighting, audio prompts, and even optional light towers ensure operators are instantly made aware of problems.

Low Energy Consumption
inForce consumes a fraction of the electricity required to support a PC or even a thin client or all-in-one shop floor PC.

Simple, Automated, and Central IT Management
From a central server application, all inForce settings can be adjusted and immediately all endpoints update automatically. The simple act of placing new firmware on the server automatically updates each endpoint.

Visually Announces Your Lines are State of the Art
Every manufacturer takes pride in their lines. inForce’s elegant custom housing and its vivid and dynamic display announces to visitors or customers that your factory is at the pinnacle of information management and process control.

Easy Setup and Maintenance
With a full touch screen display, configuring the initial setup and ongoing IT maintenance is simplified.

Assured Barcode Acquisition
Since inForce is actually a mini Windows-based computer, it is capable of implementing continuous barcode scanning for a moving conveyor. As failsafe, if a barcode is not acquired, the system stops conveyor movement and informs the operator why.

Flexible Mounting Options
The inForce console design accommodates a vast array of mounting options to make installation easy. It’s articulating and locking rear bracket can swing out to act as an integrated desktop stand. If you wish to use any VESA arm or mount, such as used with all PC monitors and TVs, it is VESA compliant. Or, pass the provided ballistic strap through the bracket slots to fasten it to a surface. And of course, the provided mount holes enable direct-attachment when desired. It even mounts under-shelf.

CE Certified
CE certification ensures safety and reliability in factory environments that are often particularly hostile in terms of EM interference.

Future Proof & Expandable
inForce is more than a single-use device. It is a true miniaturized computer incorporating a compact Windows operating system. As a true computer, inForce may be a conveyor control and MES portal today, but can evolve to deliver richer and broader functionality in the future through updates.
