Wireless to automate tank storage level monitoring

"We don’t see any reason or benefit to using cables!" says storage site manager.

FH Tank Storage  is using Emerson Process Management’s Rosemount® wireless level and pressure transmitters to provide overspill protection at its Kalmar storage terminal on the east coast of Sweden. 
FH Tank Storage AB

They have installed a plant-wide Smart Wireless network, DeltaV digital automation system, and AMS Suite predictive maintenance software to automate tank storage level monitoring. This enables FH Tank Storage to meet the latest environmental and safety requirements, as well as improve the efficiency, accuracy and reliability of level monitoring and the safety of terminal personnel.
This Smart Wireless network has enabled measurement data to be processed without the need to install new cabling, a cost saving of between €50,000 - €100,000. New cabling would require extensive groundwork which would disrupt operations and fuel tanker traffic around the site.

The Rosemount transmitters are deployed on the storage tanks and transmit measurement data to Emerson’s DeltaV system installed in the main control room. AMS Suite helps operators monitor the health of both the wireless network and the individual transmitters, and improves the efficiency of maintenance staff by identifying any faults and reducing the number of trips into the field.

“Emerson’s Rosemount level, pressure and temperature transmitters, and the Smart Wireless network, have enabled us to implement a cost-effective automated measurement system,” said Lars Ferm, Site Manager, FH Tank Storage. “They have also improved the monitoring of tank levels and have provided a fully approved overspill protection solution.”

The FH Tank Storage terminal has a capacity of approximately 13,000m3. The 68 tanks, ranging in size from 10m3 up to 2100m3, are used to store solvents, petrol and a range of chemicals. Increasingly tight environmental regulations required overspill protection to be added to all existing tanks, with new level switches needed to trigger an alarm should levels rise above preset levels. 

Previously, tank level measurements were performed manually. This required operators to climb to the top of tanks in challenging winter conditions, putting them at risk of injury. The monthly checks took a whole day and involved the use of dipping ropes, calculating volumes, and updating a white board in the main control room. Although a rigid set of procedures was in place to ensure accuracy and reliability of measurements, FH Tank Storage wanted to automate these measurements to reduce risk and remove any potential human error when recording, calculating and listing tank levels.

Emerson proposed the implementation of a continuous automated measurement solution using the PlantWeb digital architecture and Smart Wireless technology to transmit accurate and up to date tank level measurements that could also be used to provide overspill protection. Rosemount devices deployed on 29 tanks transmit level and temperature data back to the latest versions of the DeltaV system and AMS Suite software installed in the main control room. A large screen provides operators with visualization of all the tanks, tank levels and any high level alarms or instrumentation failures. The solution was presented to and accepted by Länsstyrelsen, the Swedish local environment and safety authority. 

FH Tank Storage wanted to minimize the different types of devices installed, to enable easier maintenance and reduced inventory. For the smaller tanks, FH Tank Storage installed Emerson’s Rosemount 3051S wireless DP pressure transmitters. The pressure measurement of the liquid's mass and the media's density is used to derive level. The devices transmit data every minute.
A number of the larger tanks have floating roofs, making it more difficult to install DP pressure transmitters, so Emerson’s Rosemount 5402 non contacting radar level transmitters have been deployed on the larger sized tanks. Emerson’s Smart Wireless THUM Adapters are connected to each of the radar devices to transmit the data via the wireless network. The Rosemount 5402 was selected because it is suitable for almost all tank sizes, is unaffected by floating roofs, and is suitable for a broad range of liquids and gases. Measurement accuracy is not affected by dirty or corrosive liquids or by fluid properties such as density and viscosity. 

 “The Smart Wireless network was relatively simple to install and both the network and the transmitters have been extremely reliable since they were installed,” explained Ferm. We expect to continue to deploy wireless level devices in the near future as we don’t see any reason or benefit to using cables.”

There have been no overfill alarms at the site so far, and the historical information provided by the radar measurements has enabled quick and accurate answers to customer queries. Based on this success, FH Tank Storage has placed a further order for Rosemount radar level transmitters and THUM Adapters to automate 15 more tanks. In addition, 5 tanks are currently being constructed at the terminal and Rosemount radar devices are expected to provide the level measurements and overspill protection.

VOC emissions data may be invalid!

Keith Golding, MD of Quantitech, is urging stack testers and the managers of prescribed industrial processes to check the MCERTS certificates of their Flame Ionisation Detectors (FIDs). He says, “The FID fuel gas for which the certificate is valid is now specified so process operators should ensure, for example, that if the certificate specifies a Hydrogen/Helium mix, any compliance monitoring must also use this mixture or results will be invalid.

“Users of the Sick Bernath 3006 need not be concerned because the MCERTS field test was conducted with both fuel gas options – Hydrogen and Hydrogen/Helium mix. However, Hydrogen is by far the more preferable option.”

The fuel gas for FIDs is an important issue because H2/He gas is at least three times the cost of Hydrogen gas, so one might assume that all FIDs would run on Hydrogen. However, some FID manufacturers are unable to achieve the MCERTS performance requirements whilst running on Hydrogen and have to resort to the more expensive H2/He mixture.

This situation is exacerbated by the high fuel gas flow rates (up to 180cc/min) that are required by some FIDs. In contrast, the market leading Sick Bernath 3006 portable FID has an MCERTS certificate to confirm high performance levels using Hydrogen gas at very low flow rates (20cc/min).

Explaining the significance of the fuel gas, Keith Golding says, “The use of this expensive gas mixture at high flow rates means that fuel costs can be an astonishing 27 times greater. However, the cost of the fuel gas is not the only significant issue; high flow rates necessitate a large supply of gas which can create logistical problems and health and safety issues when transporting large bottles in the field.

“Typically the 3006 is able to operate for a full working week from one small 1 litre bottle of Hydrogen, so the MCERTS approved ability of this instrument to run on Hydrogen at very low flow rates is a major advantage to process operators and stack testers.”

Software improves production efficiency and quality

EETechnologies recently completed a full implementation of Aegis’ Manufacturing Operations Software (MOS). This was effective in fulfilling their strategy to improve efficiencies and quality by streamlining and controlling process planning and launch, process tracking and control, and quality and test management. “Speed, control and visibility are core to competitiveness. We utilize technology to connect data to all of our factory processes for our customers’ benefit”, commented Sonny Newman, President of EE Technologies.<

Aegis MOS provides the tools needed by production staff to translate engineering designs into manufacturing documentation. Aegis provides support for virtually every CAD type and simplifies programming of the machines that use the CAD data. It allows EET to automate their revision control processes; it also automates the distribution of information to operator workstations in sufficient detail for quality product building. All of this is achieved with a system which, being paperless, achieves an EET environmental corporate objective.

During manufacturing, materials are related to individual machines and stations at the point-of-use and are electronically validated against job parameters. As units travel through each station, their correct, validated material setup is guaranteed, and each unit then automatically inherits the currently loaded material set. This ensures that the right product is at the right station at the right time for the right job, and provides EET’s customers with total traceability.

Users can now determine where any work order is located throughout the factory in real-time. Customer service often depends on delivering the information they need when they need it. Aegis allows EET to track WIP status and provide predictive job completion times. This is important to EET’s customers.

Quality has to be built into any manufacturing process. The Aegis software collects data in real time, providing EET with the information necessary to build the product correctly, verify its quality during production and facilitate corrective actions. This data is also available for reports, visualizations, and real-time dashboards that can be configured and used by EET to constantly improve quality and efficiency. Traceability of every product is also achieved; this allows failures and rejections to be tracked down and eliminated before they become an issue for the customer.

EET’s Director of Operations, Clay McElhany, summarizes Aegis MOS’s benefits: “Investing in technology is just one of the ways we provide world class service to our customers. With Aegis, we have instant visibility of the process and product. We continually improve our processes to be more efficient and provide our customers with the best quality, delivery, and costs.”

Safe 2 wire Coriolis flowmeter - a first!

Coriolis flowmeter achieves superior performance and safety without the need for external adapters or barriers

The Promass E 200 Coriolis flowmeter, from Endress+Hauser, is the world’s first Coriolis flowmeter with true two-wire 4-20mA HART technology. The Promass E 200 is the only two-wire Coriolis meter with a full 16 mA of measurement span without the need for excess adapters, power supplies or barriers.

This advanced meter design results in simplified integration into existing control systems, and allows the flowmeter to be used with DCS, PAS, PLC and other remotely operated controller systems. The 4-20mA interface makes it easy to replace legacy flow sensors without any change in field wiring. In many cases, the Promass E 200 can simply be “dropped in” to replace an existing flowmeter, without the need for additional hardware or rescaling of control systems.

"The Promass E 200 is the world’s safest Coriolis meter because its two-wire technology enables it to be used in intrinsically safe applications for Class 1 Division 1 locations. The Promass E200 has been submitted for a SIL-2 rating for critical applications and complies with NE43 (NAMUR) safety standards, including operating down to 3.6 mA in a fail-safe condition. Self-monitoring and error diagnostics are standard features that are designed in strict accordance with the specifications of NE107 (NAMUR)."

It has built-in diagnostics, and displays clear text errors and root causes on its local display in case of a fault. The flowmeter can also be commissioned and diagnosed with Endress+Hauser’s FieldCare software.  If servicing is needed, the HistoROM function automatic data backup function ensures automatic reconfiguration of a repaired or new meter without the need for recalibration.

This unit simultaneously measures mass flow, fluid density and temperature. In addition to liquids such as acids, alkalis, and solvents, it also measures most gases. It measures mass flow and volume flow with 0.25% accuracy, and measures density with accuracy of 0.0005 g/cm3. It operates in process pressures of Classes 150 to 600, and process temperatures up to  284 °F.

The Promass sensor is highly immune to external disturbances such as pipeline vibration, and is stable under changing process conditions such as pressure, density, temperature or viscosity.

They can supply this instrument in line sizes of 3/8 to 2 inches (DIN 8 to 50) with 904L Stainless Steel as a standard wetted material. Transmitter options include aluminium and stainless steels to meet various chemical, oil, gas, process, food, beverage and life sciences applications.

Commissioning and Diagnostics
Operator, maintenance and expert menus can be called up immediately at the touch of a button. “Make-it-run” wizards guide the user through flowmeter configuration, and “Tool tips” allow setting of additional parameter information. In the event of an error, remedy information is immediately displayed.

• Promass E 200 flowmeters produced for the Americas are calibrated on the ISO/IEC 17025 Certified Gravimetric Primary Calibration Rig at the E+H factory in Greenwood (IND US), and shipped to the customer with a NIST traceable calibration certificate. The calibration is fully traceable to national and international standards.

The Editors
The late Jim Williams, who worked for Linear Technology for nearly three decades, started as an applications engineer in the early years of the company. His contributions were many-fold. He was a legendary analog circuit designer, problem solver, writer and mentor to many engineers over the years. He died last June after suffering a stroke.
He developed an early curiosity and interest in all things electronic. He would talk about working at a TV repair shop during his early years, so he could poke around inside to find out how they worked. His passion for electronics took him to Boston, where his intellect and drive helped him find a technician’s job working on the Apollo program. Although self-taught in electronics, Jim taught and did research at Massachusetts Institute of Technology from 1968 to 1979, concentrating exclusively on analog circuit design. During this time, he began his legendary writing career—finding clear, elegant ways to describe complex and seemingly indescribable design challenges and solutions.
Before joining Linear Technology in 1982, he worked in National Semiconductor’s Linear Integrated Circuits Group for three years. In nearly 30 years with Linear, Jim had the unique role of staff scientist, with interests spanning product definition, development and support. He was consumed with developing analog circuits, helping set up instruments in the company’s labs, mentoring junior engineers in-house and customers outside, even answering his own phone. Jim maintained a lab at his home and worked there, in a lab at least as well outfitted as the one at work.
Jim Williams was named Innovator of the Year by EDN magazine in 1992 and elected to Electronic Design Hall of Fame in 2002. His outside interests spanned sports cars, collecting antique scientific instruments, art, and restoring (and using) old Tektronix oscilloscopes.

Bob Dobkin is a founder and Chief Technical Officer of Linear Technology Corporation. Prior to 1999, he was responsible for all new product development at Linear. Before founding Linear Technology in 1981, Mr. Dobkin was Director of Advanced Circuit Development at National Semiconductor for eleven years. He has been intimately involved in the development of high performance linear integrated circuits for over 30 years and has generated many industry standard circuits. Mr. Dobkin holds over 100 patents pertaining to linear ICs and has authored over 50 articles and papers. He attended the Massachusetts Institute of Technology.

The NSG 3040-DDV is also available in an ERC (Exclusive Remote Control) version, which is controlled exclusively by a PC running Teseq’s WIN 3000 software.

When used with automatic accessories such as the VAR 3005 or INA 6502, the NSG 3040-DDV features manual, automatic and programmable control of EUT power ON/OFF switching. EUT power can be switched off automatically in the event of an EUT failure or overload.

Reducing cost for semiconductor characterisation and test

Digital Per-Pin Parametric Measurement and High-Density Source Measure Unit Modules Ideal for Semiconductor

The capabilities of National Instruments' PXI platform for semiconductor characterization and production test have been extended with new per-pin parametric measurement unit (PPMU) modules and source measure unit (SMU) modules. The NI PXIe-6556 200 MHz high-speed digital I/O with PPMU, the NI PXIe-4140 and NI PXIe-4141 four-channel SMUs reduce the cost of capital equipment, decrease test times and increase mixed-signal flexibility for a variety of devices under test.

With the NI PXIe-6556 high-speed digital I/O module, engineers can generate and acquire a digital waveform at up to 200 MHz or perform DC parametric measurements with one percent accuracy on the same pin, simplifying cabling, decreasing test times and increasing the density of the tester. In addition, engineers can nearly eliminate timing skew due to different cable and trace lengths to the device under test with the built-in timing calibration feature that automatically adjusts timing for these differences. The NI PXIe-6556 comes with an option to switch in another NI SMU for higher precision, and engineers can trigger parametric measurements based on hardware or software triggers.

The NI PXIe-4140/41 SMU modules provide four SMU channels per PXI Express slot and up to 68 SMU channels per PXI chassis in 4U of rack height to simplify testing of high-pin-count devices. With sampling rates of up to 600,000 samples per second, engineers can drastically reduce measurement times or capture important transient characteristics of the device. Additionally, the NI PXIe-4141 features next-generation SourceAdapt technology that engineers can use to custom tune the SMU output response to any given load to achieve maximum stability and minimum transient times. This capability is not possible with traditional SMU technologies.

Combined with NI LabVIEW system design software, these new PPMU and SMU modules add to the modular software-defined approach to semiconductor test by increasing quality, reducing cost and decreasing the time of test across validation, characterization and production. LabVIEW combines the flexibility of a programming language with the power of an advanced engineering tool so engineers can meet unique, custom requirements.

Event manager add-on

AFCON Software and Electronics has announced the release of Pulse V1.50 SCADA/HMI software with a new and unique add-on called Event Manager, the best Control Room management software integrated in a SCADA/HMI system.

Pulse is the most recent evolution of AFCON's proven P-CIM solutions for SCADA/HMI.
The latest version, Pulse V1.50 is packed with new features that enhance operator productivity and situational awareness. It offers important security features and streamlines the process of configuring the system. In addition, a wide variety of new templates were added to facilitate the development of new screens, exposing system designers to readily available functionalities.

The Event Manager Add-on module helps Control Room operators respond efficiently to events by providing access to critical information, beneficial step-by-step procedures and real-time availability of human resources.

“This new add-on extends the SCADA/HMI role by providing operators and supervisors tools to handle foreseen contingencies by guiding them through the various steps of an organization's predefined procedures. It also helps the organization with the subsequent debriefing and analysis by recording the actual activities that took place and their respective timing”
said Mr. Gabi Weiss, AFCON Software and Electronics' General Manager.

Key benefits of this module are reducing the risk for human errors and ensuring that policies and procedures are followed uniformly. Using the Event Manager in organizations/facilities improve regulatory compliance and increase response efficiency. Furthermore, it also reduces the need for comprehensive training.

Users can now also meet their growing security requirements through Nice DVR Client interface added in this release. This integration allows operators to both view live video and playback along with controlling PTZ camera movement directly from the video show or through direction buttons.

St St cylinders for extreme conditions

A new generation of stainless steel cylinders specifically designed to withstand the extreme conditions experienced in the food industry has been introduced by ASCO Numatics. Quick and easy to install, CIX cylinders feature stainless steel covers, tube and rod, no retention areas and a special front cover design. They are suitable for use in saline or lactic environments which are subject to frequent wash-downs using cleaners and active detergents.

CIX cylinders can be fitted with IP69K magnetic positioning detectors and feature special seals which are resistant to very high pressure jets. The seals can be replaced quickly and easily without disassembling the cylinder. This reduces the time required for maintenance by 70 per cent - minimising machine downtime and maintenance costs.

Operational excellence at clean-coal power plants

The U.S. Department of Energy (DOE) has deployed a first-of-a-kind operator training simulator for an integrated gasification combined cycle (IGCC) power plant with carbon capture using innovative simulation software-based training solutions from Invensys Operations Management.

Implemented at the National Energy Technology Laboratory’s (NETL) Advanced Virtual Energy Simulation Training and Research (AVESTAR) Center in Morgantown, W.Va., Invensys Operations Management’s SimSci-Esscor® DYNSIM® high-fidelity simulator will help train operators for new IGCC plants now being built in the US. An AVESTAR facility identical to the one at NETL is also in place at the West Virginia University National Research Center for Coal and Energy. It also uses a DYNSIM high-fidelity simulator and will be used to assist NETL with research and education.

“IGCC with carbon capture holds tremendous promise as a low-cost, clean energy source so IGCC plants are expected to be a key resource for the provision of clean fossil power in the near future. Fulfilling that promise, however, requires an adequate supply of well-trained operators,” said Tobias Scheele, Vice President, operations management applications, Invensys Operations Management. “The DOE is using our DYNSIM simulator, just as airlines use flight simulators to train pilots before they take to the air, to help future IGCC plant operators achieve operational and environmental excellence.”

The U.S. Energy Information Administration estimates that, based on current usage rates, the US has enough coal to last more than 200 years, but if plants continue to use conventional fossil fuel technologies, they will emit unacceptable levels of CO2 and other pollutants. IGCC with carbon capture offers an environmentally friendly alternative by capturing 90 percent of the CO2 produced by traditional fossil-fuel burning processes while at the same time reducing sulfur, mercury and other NOx emissions.

However, IGCC is also a complex process requiring highly trained operators. Many plants are now in various stages of design or construction in the United States and there is a pressing need for a well-trained work force. The DOE is therefore, providing high-fidelity simulated environments that will enable trainees to learn to interact with controls that are almost indistinguishable from those they would encounter in a real plant.

“IGCC is highly complex, mostly because personnel must learn to operate what is effectively both a chemical processing plant and a power plant. To teach them how to do that we must simulate the chemical process of coal-gasification with CO2 capture together with combined-cycle power generation,” said Stephen E. Zitney, Ph.D. and director of NETL's AVESTAR Center. “No one has ever done that before, but now with help from Invensys, we can simulate routine operations, disturbances and malfunctions, as well as routine and emergency shutdowns. We can even simulate operations and train operators on different coal and biomass feed stocks.”

The next phase of the project, already well underway, extends simulation from the control room to outside plant operators, or field operators, expanding the SimSci-Esscor solution to a 3-D virtual reality experience using Invensys Operations Management’s EYESIM® immersive training simulator. Wearing a stereoscopic headset or eyewear, IGCC field operators can coordinate activities with control room operators. Immersed in an EYESIM virtual environment, field operators can move and interact as if they were in the real plant. The environment is fully interactive with the simulation models, so actions taken by a field operator will have an impact on the process and actions performed in the control room will change the information visible to the field operator. As a result, field and control room operators will be trained to coordinate their activities and perform collaboratively as a team.

New pressure sensor family

Balluff has introduced BPS, a newly developed series of pressure sensors with IP 67 protection for use in gaseous and liquid media. The rugged devices feature a high-quality, long-term stable ceramic load cell and an especially attractive price/performance ratio, simple installation, high operating comfort and high preci-sion. A large, bright and easily visible display ensures immediate status overview. This shows not only the current system pressure in bar, mbar, PSI and MPa, but also features fast and simple configuration of the sensors according to the VDMA standard, using 2 keys and intuitive menu guidance.

With 11 pressure range versions the BPS sensors cover all the im-portant ranges from -1…0 bar up to 0…600 bar for monitoring process media in factory automation. Typical applications include hydraulics monitoring as well as pneumatics equipment. The new Balluff pressure sensors, available in the standard model with plastic housing and in the high-end version with stainless steel, offer either two switching points or one switching output plus analog channel (0…10V or 4…20mA).

Thanks to their highly compact design the sensors can be easily located in the control cabinet without taking up valuable space. The display with operating panel and electrical connection can be rotated independently of each other by 320° with respect to the flange. Adapting to different process terminations using G ¼ internal threads is easily accomplished using optional adapters in various sizes and styles.

The high-end models with their stainless steel housing and expanded temperature range were especially designed for demanding applica-tions in harsh environments, making them ideal for use with wind pow-er turbines, offshore installations as well as HVAC technology.

Outdoor housing

All too often it is believed that 19” equipment is only suitable for the indoor environment and that for an outdoor application a special enclosure, to create the perfect environment, requires development at huge cost. Rittal’s standard range of outdoor enclosures, based on the TS 8, have a whole range of accessories available, including a full range of 19” components suitable for outside use.

Customers can select from a large range of 19” angles, in varying U heights, which can be fitted at the front, rear, or both, to a range of static or adjustable shelves, to swing frames and a host of cable management that will meet most requirements.

Coupled with a range of specifically designed outdoor heating and cooling options from 10W to 800W heaters, simple fans and filters or heat exchangers and air-conditioning units, Rittal can create the correct environment for the installed equipment wherever it is finally located.

All this can be installed within a high security outdoor enclosure manufactured from a range of alternative materials, with global approvals and high IP ratings.

The new contact has a compact and robust design, and is designed to be used instead of a power contact in the Han® HC Modular 250 mounting frame. The flexible configuration and arrangement make coding possible. A commercially available screwdriver is all that is needed for assembly and dismantling.

The new contact is vibration-proof, and offers low contact resistances between hood and housing. It supports crimping in accordance with DIN EN 46235, and is compatible with Harting's existing HC 250 holding frame.

The Han-Modular® series is a highly versatile, open connector system that allows users to configure connectors to match the needs of particular applications. The new Han® HC Modular 250 PE supplements more than 30 existing modules for handling electrical, optical and pneumatic signals.

Modular safety system for safety-related applications expanded by AS-i

The Siemens Industry Automation Division has expanded its Sirius 3RK3 modular safety system by a new central module with AS-i (AS-Interface).

Sirius 3RK3 Advanced can be used as an AS-i safety monitor, and thus expands standard AS-i networks for safety-related applications. Typical applications include the collection of sensor signals in widely spaced plants, slave-to-slave communication in modular machine concepts, safety-related communication with plant components, or distributed switching-off of drives via the AS-Interface.

The new module is suitable for standard and safety-related signals on the AS-i bus, and has 12 independent AS-i enabling circuits. The quantity structure and functionality of the Sirius 3RK3 Advanced have been greatly increased compared to the Basic version. For example, nine expansion modules can now be connected instead of seven, and expanded cyclic data exchange is possible over Profibus. The functionality of the MSS ES engineering software has also been expanded. It is now possible to download the parameter settings and carry out online diagnostics of the unit over Profibus.

The macro function is also new with which function units can be combined in a library. The macros can be exported and imported, and thus reused in other projects.

New data portal goes live!

Maximum speed and easy searching and finding are the main advantages of the new EPLAN Data Portal which already includes data for more than 120,000 devices. Users benefit from access to the latest, up-to-date data which can be more quickly and easily integrated in engineering using the new EPLAN Platform 2.0.

In addition to numerous new and expanded functions, Version 2.0 of EPLAN Data Portal provides many new component data from manufacturers like Festo, ABB, Phoenix Contact, Endress+Hauser etc.
Following the launch of the EPLAN Platform 2.0, the new EPLAN Data Portal 2.0 has now gone live. Users are enjoying new time-saving functions in the online portal that make it easier to select and use device data and components. The integration of much more manufacturer and device data promises significant practical benefits. A new portal member is Leuze Electronic, manufacturer of optoelectronic sensors who has integrated EPLAN macros of selected switchgears as well as many safety oriented sensors. In time for Version 2.0, Festo has also provided a selection of pneumatic components.

More manufacturers – more data

Mitsubishi Electric has joined the list of new manufacturers with data for PLCs and converters and Dehn + Söhne expanded the offering in lightening and surge protection. But that's not all: ABB has updated its data and Phoenix Contact has adjusted its already extensive range of products. At the SPS/IPC/DRIVES trade fair, Blomberger will present the next update, so that their device data will also support the latest EPLAN Electric P8 2.0 functionality. Future exciting perspectives: the planned integration of Endress+Hauser, which will be announced in Nuremberg.

Function by function
Valuable manufacturer data aside, users can look forward to many new portal functions. One of the eagerly awaited highlights is the "unique ID" which clearly identifies an article in the EPLAN Data Portal. This ID allows data from the portal to be updated even if the local part number is changed. And if the manufacturer so desires, the device data can now be displayed and filtered according to regional availability. Users can quickly and easily select the data relevant to their target market and concentrate on the relevant components. The optimized user interface is also a decisive factor. For example, it now has filter options that can be hidden which significantly speeds up page loading times.

Faster searching, easier finding
Data transparency has been improved by now displaying the number of articles per product group including all subgroups in the manufacturer catalog. This makes it easy to select from many extensive catalogs – time-consuming page-turning is a thing of the past. Another highlight is the new accessory lists for users who used the optimized accessory management in Versions 2.0 of the data portal. Other new features: automatic download of function template macros, referenced parts that are already complete for the mounting layout, and the life cycle status of previous and subsequent parts so that data is always up-to-date.

Fast, easy, convenient: configurator technology
Next step to improve availability and usage of CAE component data is the integration of supplier specific component configurators into the EPLAN Data Portal. Currently Rockwell, Endress + Hauser and EPLAN are running a common project to create a seamless interface between E&H product configurator and EPLAN Data Portal. The engineer is able to configure the needed E&H devices guided by the configurator and then drag & drop the detailed CAE data directly into his electrical project documentation – simply genius high end engineering. The integration of Rittal Therm is another technological milestone. All necessary components, assemblies and accessory parts are simply configured and then mounted in the 3D mounting layout of the enclosure.

ATEX approved LBFS level switch

No additional Zener barrier required thanks to ready-for-use isolation module PROFSI3 LS

Baumer’s multi-purpose LBFS level switch is now available in three different ATEX configurations which enable safe level detection in explosive gaseous and dusty atmospheres, typically found in the chemical, pharmaceutical, or food industries. Baumer uses a highly specialised protective design for the ATEX versions of the LBFS. Thanks to this, versions Ex ta for dust (zones 20, 21, and 22) and Ex nA for gas (zone 2) can be used without a Zener barrier because the housing itself already provides all the necessary protection. This is very cost-effective because usually all sensors for hazardous areas require a Zener barrier. The ATEX certifications cover zones 0, 1, and 2 (gas) as well as zones 20, 21, and 22 (dust). Quick installation and ease of use is also ensured for version Ex ia for gas (zones 0 and 1). For this version, Baumer provides the ready-for-use isolation module PROFSI3 LS which is specially designed for use with Baumer’s level switches LBFS and LFFS. This dedicated isolation module saves users the time and effort of selecting and configuring an additional Zener barrier to operate the sensor.

The PROFSI3 LS can operate with DC voltages from 22 VDC to 120 VDC as well as AC voltages from 90 VAC to 253 VAC. The LBFS is based on the frequency-sweep technology, a method particularly suitable for precisely measuring the level of solids and powders. As the processing of such materials often creates explosive dust, the new ATEX versions open a wide range of new applications particularly valuable for typical LBFS users in the chemical and pharmaceutical industries.

But industries like oil and gas, energy production, and milling will also find this new level switch convenient. The ATEX versions of the LBFS level switch can easily be adapted to the needs of very diverse applications thanks to a wide range of available process connections including G½”, G3/4”, G1”, G½” hygienic, G½” for reverse assembly, M18x1, and G3/4 NPT. More connections are available upon request.

The intrinsically safe PROFSI3 LS interface shields the safe area from the hazardous area through galvanic isolation. The level detected within the hazardous area is transmitted to the safe area through a single-pole double-throw relay.
