Large diameter pneumatic cylinders.

Festo has launched a new series of efficient, durable and technically advanced large diameter ISO cylinders. The cost-effective DSBG series is the lightest diameter cylinder in its class, weighing 20% less than its predecessor, and enables machine builders and engineers to optimise their systems for increased process efficiencies.

With heat-resistance up to 150°C and ATEX certificated variants available, the DSBG is extremely flexible in use, delivering excellent performance even in harsh conditions. The cylinders are available in four sizes, 160, 200, 250 and 320 mm making them ideal for mining, steel industry and process automation applications.

The DSBG series is available with fixed elastomer or adjustable air (P or PPV) cushioning as standard. With the P cushioning option an elastomer cushioning ring absorbs low-level impact energy and reduces noise and vibration. Even with the elastomer cushion, the DSBG is very precise in its end positions. The rubber component becomes fully compressed between 3 and 4 bar, and the piston achieves repeatable metal-to-metal contact. At higher energy levels, P cushioning is supplemented with additional adjustable pneumatic PPV cushioning. With optimised cushioning air flows the piston achieves gradual deceleration for a smoother, shock and vibration free operation.

“With a stronger design the DSBG series offers improved protection against overpressure, easier handling and increased operating efficiency,” says Steve Sands, product manager at Festo. “The DSBG is a highly versatile cylinder and with its matching proximity sensors, mountings and a complete selection of pneumatic connection technology available, we are able to offer a complete robust solution.”

PSUs meet medical performance specifications.

The Xsolo power supplies, from Excelsys Technologies, have been designed and tested to meet both the B and BF type requirements per the IEC 60601 standard.  This makes them suitable for applications that need these levels of performance for power supplies used in medical applications. Excelsys’ testing procedures were performed in accordance with requirements for B (body) and BF (body floating) medical end products. The goal of the testing was to help manufacturers optimize their medical designs to achieve the highest performance and safety levels, enabling first-pass success during agency approvals.

B-type applied parts, which are not typically attached to the patient for long periods of time, include LED lighting, medical lasers, medical imaging (e.g., MRI), hospital beds and phototherapy equipment. Type BF applied parts have conductive long-term contact with a patient. These can include incubators, therapy systems patient heating and cooling equipment, ultrasound monitoring, cardiac monitoring, as well as long-term diagnostic equipment and blood pressure monitoring. To demonstrate that its power supplies are suitable for these applications, Excelsys tested both its basic and low-leakage Xsolo models (XS1000-48N-000 and XS1000-48N-004) to the 60601 standard using an AC source providing 264 VAC at 63 Hz to recreate worse-case conditions.  Copies of the test report are available on request.

“Excelsys Technologies developed the XS series of power supplies with medical applications in mind,” said Gary Duffy, Excelsys CEO. “By testing our power supplies to the 60601 B and BF specification, we help manufacturers with the task of certifying the end medical device as an applied part for their intended applications with respect to safety and leakage currents.”

Manufacturers often need to incorporate multiple power supplies into a given system and still meet stringent requirements. To help meet these requirements, Excelsys also offers low-leakage power supply versions, which enable the incorporation of multiple power supplies into various medical-type rated systems, depending on the application.  As a world-class power supply manufacturer

Loading metering skids.

Loading Metering Skids are a certified solution for custody transfer of light hydrocarbons including gasoline, diesel, jet fuel and marine gas to and from tanker trucks, rail cars and ships.

Endress+Hauser introduces the Loading Metering Skid (LMS), a certified solution for custody transfer of light hydrocarbons including gasoline, diesel, jet fuel and marine gas to and from tanker trucks, railcars and ships.

The skid includes a Promass Coriolis mass flow meter, batch controller, grounding system, temperature sensor, digital start-stop valve, Y-strainer, isolation valves, frame, piping, an Ex d junction box, and other associated components. The skid is certified for custody transfer per MID Directive 2004/22/EC, Class 0.5.

The Promass Coriolis meter provides outputs for mass flow, density and volume. This is especially important for the future as trends indicate light hydrocarbons will go from volume to mass billing, as is already in place for LPG custody transfer.

Due to the lower pressure loss of the Promass Coriolis mass flow meter as compared to other types of flow meters, the loading/unloading station can operate at higher flow rates. This results in faster loading times, or lower pump energy consumption at the same flow rate.

Three versions of the skid are available: Model LMS080 for truck loading has a 3-inch line and a maximum loading rate of 3,300 lb/min (1,500 kg/min); Model LMS100 for railcar loading has a 4-inch line for a maximum loading rate of 5,500 lb/min (2,500 kg/min); and the LMS150 for ships has a 6-inch line for a maximum loading rate of 13,670 lb/min (6,200kg/min).

The LMS skids are completely assembled and certified for easy installation and commissioning at a loading or unloading depot. Skids are available for horizontal or vertical installation, including a loading arm. Options include an air eliminator, prover connections, pressure sensor, grounding
system and a 2-inch blending line. The blending line can be connected to the metering skid and controlled by the batch controller via three different recipes.

Open and standardized digital communication interfaces allow smooth integration to the Endress+Hauser Terminal Management System, Tank Vision Gauging system, or similar inventory management systems from other suppliers.

The skid also connects to Endress+Hauser Terminalvision software for handling of requirements for road, rail and barge loading depots and terminals. The skid’s open control and monitoring system is designed to interface to most supplier systems used for access control, loading and weighbridges.

•The Loading Metering Skids will be exhibited at the International Liquid Terminals Association show, June 1-3, 2015, in Houston (TX USA). Booth #605

Connector offers tool-free installation in industrial Ethernet applications

In addition to offering the benefits of high connection density in industrial Ethernet applications with transfer rates of up to 10 Gbit/s, Harting’s new M12 PushPull connector allows manual installation without the need for special tools, thus speeding up its installation in tight spaces.

The M12 PushPull locking solution can be plugged rapidly and securely and indicates correct assembly with a clearly audible click. With its anti-slip safety ring, the connector can be reliably gripped and released under the most difficult conditions. This mounting solution also offers robustness and vibration resistance under demanding application conditions, such as those encountered in the rail industry. The bulkhead mounted connector is also threaded to be backwards compatible with standard M12 cable connectors.

The absence of the unnecessary working space for tool access allows the connectors to be installed in more compact spaces, along with a higher packing density if several slots are required.

Improving extrusion machine efficiency & accuracy.

The manufacturing site of Clariant at Izmit, Turkey, has adopted the latest high performance Emerson technology to help it overcome issues surrounding maintenance and inefficiency. Control Techniques’ Unidrive M, in tandem with a Leroy-Somer Dyneo® permanent magnet synchronous motor from Emerson Industrial Automation, is being used on a process-critical extrusion machine in order to help boost both the efficiency and accuracy of its work for customers in the plastics and chemical industries.

Clariant, one of the world’s leading speciality chemical companies, was experiencing issues with its previous DC motor and drive system on an important extrusion machine at its Izmit facility. The plant, located around 70 km east of Istanbul, centres on colouration solutions for plastics and polymer products, as well as a host of other products ranging from PVC stabilisers to waxes for polyolefin compounds. The motor and drive package had been in service for many years but was now ageing and proving inefficient. Furthermore, frequent maintenance was required and, as a result, the facility sought an alternative solution.

Having researched the market, Clariant opted to move away from its previous supplier of motors and drives in favour of a complete drives and motors solution from Emerson Industrial Automation.

“Aside from new technology and increased energy efficiency, the choice was based on the user-friendly and easy-to-use parameters of the Unidrive M600,” said Serdar Kiyi, technical manager at the plant. “We are now using the package to leverage more efficiency, accuracy and reliability from the extrusion machine than was possible using our previous systems.”

Among the main technical features of the Unidrive M600 that appealed to Clariant was its ability to support sensor-less open loop control. This mode offers impressive dynamic performance and enables more compact and higher efficiency motor technologies to be used, such as Dyneo®. It also supports simple positioning without the need for encoder position feedback.

The Unidrive M600 also offers a high performance onboard PLC with a real-time task that can be used for straightforward logic control, speed following and digital lock to enhance drive application capability. The drive also features CODESYS technology for machine control programming.

“We really like the user friendly menu and parameters, as well as its compact, slim design,” says Mr Kiyi. “Since installing the new solution from Emerson Industrial Automation, the extrusion machine has been working with markedly higher efficiency and precision, and our total throughput has increased by around 10 per cent.”

Milestone on the road to operating emission-free ferries!

Siemens delivers electric propulsion system and charging stations with lithium-ion batteries charged from hydro power

This isn't really an instrumentation topic but as the Read-out office overlooks the daily ferry service to Árainn we thought the story interesting. Some of the conditions described such as a weak power grid are duplicated here on the Irish wild Atlantic coast.
Ferry only uses 150 kilowatt hours (kWh) per route and reduces cost of fuel by 60 percent
The world's first electrical car and passenger ferry powered by batteries has entered service in Norway. The ferry only uses 150 kWh per route, which corresponds to three days use of electricity in a standard Norwegian household. Built in conjunction with shipbuilder Fjellstrand, Siemens installed the complete electric propulsion system and put up charging stations with lithium-ion batteries which are charged from hydro power. With the change to battery, ship owner Norled is reducing the cost of fuel by up to 60 percent. The Norled ferry represents a milestone on the road to operating completely emission-free ferries along Norway's long coastline, with at least 50 other routes currently able to sustain battery-operated vessels.

Because the power grid in the region is relatively weak, Siemens and Norled decided to install three battery packs: one lithium-ion battery on board the ferry, and one at each pier to serve as a buffer. The 260-kWh-units supply electricity to the ferry while it waits. Afterward, the battery slowly recoups all of this energy from the grid until the ship comes back again to drop off passengers and recharge. Charging stations are housed in small buildings about the size of newsstands. The ship’s onboard batteries are recharged directly from the grid at night when the ferry is not in use. Each battery pack corresponds to the effect of 1600 standard car batteries. The Norled ferry will consume around two million kWh per year, whereas a traditional diesel ferry consumes at least one million liters of diesel a year and emits 570 tons of carbon dioxide and 15 metric tons of nitrogen oxides. “We are proud to operate the world’s first electric ferry”, says Sigvald Breivik, Technical director of Norled. “Siemens has been a great partner in finding innovative and sustainable solutions for our environment.”

On board the ferry, Siemens installed its electric propulsion system BlueDrive PlusC. It includes a battery and steering system, thruster control for the propellers, an energy management system and an integrated alarm system. The integrated automation systems control and monitor the machineries and auxiliaries on the ferry and are connected via Profibus to all other subsystems.

“We are both optimistic and excited about this technology and how it will help shape the future of environmentally friendly maritime technology,” says Mario Azar, CEO of the Siemens Business Unit Oil & Gas and Marine. “We were pleased to apply our expertise in this field including electric propulsion systems to such a worthwhile project.”

Unlike many electric cars, the emission-free ferry was developed from the ground up. The ferry, which is 80 meters long and 20 meters wide, is driven by two electric motors, each with an output of 450 kilowatts. It is made exclusively of light aluminum rather than the steel normally used in shipbuilding. This makes the ferry only half as heavy as a conventional ferry, despite its ten ton batteries and a capacity for 360 passengers and 120 vehicles. An aluminum hull also has double the lifetime as steel hull, which leads to lower maintenance costs.

Ship owner Norled operates on the ferry link across Sognefjord between Lavik and Oppedal, Norway. The fully electric ferry travels six kilometers across the fjord 34 times a day, with each trip taking around 20 minutes. The unique solution is a result of a competition that Ministry of Transport and Communications and the Norwegian Public Roads Administration launched in 2010. Batteries are expected to become considerably more efficient and less expensive in the next few years, which tip the scales further away from diesel as the most popular fuel source.
Ampere nominated for Energy Efficiency Award
• This vessel, the Ampere, has been nominated for Nor-Shipping 2015 awards, which recognise achievements in three areas – energy efficiency, innovative ship design and young entrepreneurship.

The final part of the event will be devoted to showing how cost-efficient embedded vision systems can be built with IDS cameras. This will include general information and future trends on embedded systems, together with detail on the IDS embedded portfolio and application examples of practical use.

High-accuracy current transducers!

The new series of IT xx5 transducers for non-intrusive and isolated nominal measurements of DC, AC and pulsed currents from 60 A to 600 A has been announced by LEM. This extends the company's range of high-accuracy current transducers. The range includes 4 new models: IT 65-S, IT 205-S, IT 405-S and IT 605-S.
These new models offer an extended operating temperature range of -40 to +85°C, compared to the +10 to +50°C temperature range of previous IT models, allowing their use in a wider range of applications, including high precision power supplies, medical equipment, calibration units, precision and high stability inverters, power analysers and metering.

These new models provide the high performance of fluxgate technology based transducers across the extended temperature range, delivering extremely high accuracy with linearity over temperature range better than 12 ppm, and a low offset over temperature range between 36 to 400 ppm (according to the model). The fast response time to di/dt step changes is less than 0.5 µs, due to a precise and consistent winding process.

The IT xx5 series has been designed to operate from a bipolar +/-15 V DC power supply and will accommodate round primary conductors of 26 and 30 mm diameter, depending upon the model used. In addition to their normal current output, the transducers offer an additional output indicating the transducer state (low or high output levels) and an external LED showing normal operation.

The new IT xx5 range is also fully compatible with the previous LEM IT range, fitting the same footprint. These transducers can be easily retrofitted into old installations while maintaining the various compact sizes for each current range and a variety of panel mounting topologies (flat or vertical), without compromising the high insulation level provided between the primary and measurement circuits.

VNA System with industry’s widest frequency coverage!

The VectorStar® ME7838A4 4-port broadband vector network analyser (VNA) system has been introduced by Anritsu.  The new analyser features the world’s widest differential broadband sweep from 70 kHz to 110/125 GHz and utilises the smallest mmWave modules to conduct highly stable and fast measurements when characterising differential devices. The new ME7838A4 provides on-wafer and signal integrity engineers with a new level of performance when conducting differential measurements so they have greater confidence in their next-generation communications system designs.

A key advantage of the VectorStar ME7838A4 4-port broadband system is the integration of the 3743A mmWave modules. Utilising an exclusive Anritsu design that incorporates nonlinear transmission line technology (NLTL), the modules are much more compact than competitive alternatives, for easy mounting on space-limited wafer probe station platens. Additionally, smaller and lighter modules improve overall performance, including superior raw directivity performance that results in superior calibration stability. Modules are available that can extend the VectorStar ME7838A4 to a 4-port 145 GHz system.

The VectorStar ME7838A4 4-port broadband system uses an internal substrate-mounted source for excellent thermal stability, resulting in industry best calibration and measurement stability of 0.1 dB over 24 hours. It also features best-in-class measurement speed of 55 ms for 201 points at 10 kHz IFBW.

Engineers benefit from unparalleled mmWave noise floor sensitivity and the industry’s only available mmWave real-time electronic power leveling that eliminates the need for time-lagging software correction tables. Because internal frequency multiplication begins at 54 GHz in the VectorStar ME7838A4 compared to 67 GHz for other 4-port broadband systems, RF cable losses are reduced for improved dynamic range and phase stability.

Installation and operating costs are reduced with the VectorStar ME7838A4. Probe station positioner costs are lower due to the compact size and lighter weight of the modules. There is also significant savings from the longer interval times between calibrations.

Anritsu’s advanced True Mode Stimulus is available for the VectorStar ME7838A4. With the option, engineers can program two internal signals to deliver a true 180⁰ (or 0⁰ for common mode) differential signal for comprehensive device analysis.

How's your machine's health?

Emerson Process Management has introduced the CSI 3000 Machinery Health Monitor, a compact protection system for a wide range of machinery such as pumps, compressors, centrifuges, blowers and generators.

Field-mounted, dual-channel protection
for rotating assets
The CSI 3000 delivers protection data in situations where a standard rack-based system simply will not fit or is not a cost-effective approach. Easy assembly and user-friendly, customisable setup means the CSI 3000 has a short path out of the box to improving availability and ensuring the safety of rotating assets.

“Emerson offers a complete line of protection monitors – from the rack-mounted CSI 6500 online monitoring system and the basic CSI 9360 Vibration/Position Transmitter, to the CSI 6300 SIS that guards against overspeed conditions,” said Björn Müller, Emerson’s product manager for online sensors. “This is another example of how we are delivering capabilities that bring stability to our user’s operations through services and technologies that reduce downtime and improve availability.”

The CSI 3000 measures shaft vibration, bearing vibration, position and speed, and generates key signals. The system provides the user with alarm outputs for each channel and does not require additional signal converters for shaft vibration and displacement measurements.
