Renold has launched a new version of Smartlink, the innovative chain monitoring technology that can be installed and operated either by maintenance engineers or OEMs. Previous versions of Smartlink have had to be installed and monitored by Renold's own engineers limiting its use to larger projects.

Now Smartlink can be owned and operated by anyone, bringing the benefits of chain monitoring to a much wider range of applications. The new Smartlink devices are supplied already fitted to a section of chain; users simply install the new chain link and Smartlink is ready to go. The new Smarlink units are available for operation on 1, 1.25 and 1.5in pitch chains. They are remotely controlled with a choice of two handheld devices, providing users with two levels of sophistication.

The simpler of the two handheld controllers is no bigger than a keyfob and enables Smartlink to be operated as an overload detector. In this instance Smartlink will provide a warning when chain exceeds a predetermined load enabling engineers to check machinery and make sure that it is safe to continue operating the system. The alarm conditions on the Smartlink device can then be reset using the remote control.

A more sophisticated handheld controller is available that is capable of downloading much more detailed information from Smartlink about the nature of the stresses and loading the chain was subjected to during a given period of operation. The data can then be analysed on a PC to identify the exact location of load peaks in the drive system using software specially written by Renold.

These developments have been possible thanks, in part, to the availability of smaller PCBs and miniature batteries that were initially developed for high-grade military applications. These new batteries are so small that Renold's team were able to integrate them with the PCB itself so that they were no longer a component on the board, they became part of it.

Speaking of the new launch Renold's Marketing Communications Manager, David Turner, says: 'This launch represents a breakthrough in chain monitoring technology and brings the benefits of Smartlink to a much wider range of engineers'. 'The new Smartlink units provide a groundbreaking opportunity to understand system loads which may be detrimental to the performance of a product or the operation of machinery'.

Dalsa has released the Falcon 1.4M100 1.4 megapixel, high-speed camera from Firstsight Vision. The new camera delivers 100 frames a second at full 1400 x 1024 pixel resolution. Even faster frame rates can be achieved through vertical windowing. The dynamic range of 57dB ensures excellent image quality.

Housed in a compact body, the new camera is ideally suited to applications in electronics manufacturing and semiconductor inspection. These include wire and die bonding, flat panel display inspection and pick and place. The high-speed capabilities also make it suitable for use in industrial metrology and general machine vision applications such as print registration and pharmaceutical inspection. The sensor provides global shuttering, global reset and concurrent integration and readout.

True global shuttering is suited to imaging fast-moving objects. It captures crisp images without smear or distortion by electronically shuttering all pixels simultaneously, even at short exposure times. This avoids the distortion of images of moving objects using rolling shutter systems.
Fully programmable via base mini Camera Link (CL), the camera incorporates exposure control, gain and offset adjustment and flat- field correction. The mini Camera Link interface allows data transmission over 10m cable lengths.

Ease of use is enhanced through direct camera control using Dalsa's CamExpert point-and-click graphical user interface. The Falcon 1.4M100 is fully compatible with Dalsa's Xcelera PoCL (Power over Camera Link) series of frame grabbers, as well as Dalsa's X64-CL and Anaconda CL vision processors.

The Wells Sanitary District waste water treatment facility has installed four Optiflux electromagnetic flowmeters to monitor the flow of sludge at the treatment plant. The newly refurbished plant on the southern coast of Maine, USA treats up to 7.5 million litres of waste water per day. Engineering consultants redesigned many of the systems and processes at the facility and replaced all the existing electromagnetic flowmeters with Krohne's Optiflux instruments.

The Optiflux incorporates advanced measurement technology, which is highly accurate even when measuring substances with a high bubble or solid content or where there is turbulent flow. The flowmeters installed at Wells Sanitary District are being used to measure sludge recirculation and monitor the amount of effluent that is treated.

In the sludge recirculation area, which forms part of the of the facility's in-line waste activated sludge process, two Optiflux flowmeters are being used to measure the throughput of sludge, which is calculated per minute and per day. Another flowmeter is installed to measure the flow of sludge being removed from the system. The fourth Optiflux is used in the treated effluent area to measure the flow of treated water that flows through the facility.

Dennis Thayler, Superintendent at Wells Sanitary District, said: 'Many people don't realise that these meters operate 24/7, under demanding conditions, so they need to offer superior performance and reliability'. 'The use of accurate and reliable meters in this environment cannot be overstated'. 'Flowmeters are essential to the overall process here - and at any treatment facility, for that matter'.

The Wells Sanitary District now meets all safety standards required by the US environmental protection Agency (EPA) and Maine's Department of Environmental Protection. The Optiflux magmeter provides precise measurement across a wide and demanding range of applications. It can achieve an industry-leading accuracy of 0.15% and reproducibility of 0.06%, even when measuring materials with high solid content or that have turbulent flow.

EnergAir has released a free guide to reducing costs in compressed air systems. Challenge Convention in Compressed Air details several ways to improve the energy efficiency of compressed air systems. Aimed at plant managers, site maintenance managers and energy managers the intention is to help address preconceived ideas about compressed air generation (one of the major energy costs to industry) that are currently the cause of huge amounts of energy waste, the alternatives can add literally tens of thousands on the bottom line.

'The industry needs to challenge convention on compressed air in order to realise the savings that can be made', according to Peter Tomlins of EnergAir UK. EnergAir believes that it can provide vital knowledge regarding the purchasing and integration of variable speed compressors, compressor sizing, balancing system pressure, providing visibility of actual energy consumption, and monitoring saving when changes are made, information that would not normally be available to individual plant and maintenance managers.

The brochure also contains real examples of how savings have been made by leading UK manufacturers such as Britvic and the equipment used to achieve those savings. The guide also aims to dispel some myths about how much difference new equipment can make without being properly integrated and offers advice on how to get the best from an existing compressor installation. The EnergAir guide to reducing the running costs of compressed air systems is available in paper format free from EnergAir and as a high-resolution pdf from the company website.

Bearings from Trelleborg Bakker improve FPSO manoeuvreability and safety. One of company's most complex projects was the supply of 42 specially designed bearings for the Sea Rose. Constructed of steel and rubber, these compensated for the flexing of the hull, lowering the stresses on the ship's structure.

As floating production storage offloading (FPSO) vessels travel further offshore to extract oil and gas, the demands on them become greater. They need to house more large pieces of machinery such as compressors and pumps. Weighing considerable amounts, these can create significant stresses on the vessel, affecting manoeuvreability and safety.

This effect is intensified by the potential severe weather conditions of deeper waters, with increased forces from waves and wind. Another complication is that the tonnage of the ship constantly changes as oil is pumped in and then offloaded to tankers. Trelleborg Bakker, an operating unit of Trelleborg Engineered Systems, has worked with leading FPSO fabricators and operators since the inception of these floating rigs.

Machinery fitted to FPSOs is commonly installed on Trelleborg Bakker bearings. These, constructed of steel and rubber, compensate for the flexing of the hull, lowering the stresses on the ship's structure. One of Trelleborg Bakker's most complex projects was the fitment of the Sea Rose. This required the installation of 42 bearings in three special designs. Each of them over 2m high and the heaviest weighing close to 10 tons, they can withstand exceptional load vertically up to 10,000kN and horizontally up to 3500kN. They are also capable of compensating for distortions up to 75mm. The Trelleborg Bakker bearings fitted on the Sea Rose are proving successful in her assignment extracting oil off the coast of Newfoundland in Canada. Technology developed for this project and others globally, allows Trelleborg Bakker to offer cost-effective bearing solutions for frames a secondO vessels worldwide.

Hansford Sensors has selected an alternative 12mm connector style, the M12, as offering the best combination of performance and price. The result - today, you can specify either the standard MS series or the M12 Connector on most of their range of vibration sensors. The main advantages of the M12 connector are its smaller size and the fact that its associated cable assemblies have a tighter bend radius.

It is a well accepted and proven connector used across many industries including process control, automation and sensing. They are particularly suitable for use in vibration monitoring equipment, the IP67/68 sealing making them usable in difficult environmental conditions often found in maintenance condition monitoring applications. With its wide use in industrial electronic equipment, the cost-effective connectors and numerous cable assemblies are readily available from electrical distributors worldwide making off the shelf delivery a reality.

Hansford Sensors has applied the connectors across the HS-100, HS-100S, HS-420 and HS-421 series of vibration sensors. All models are constructed in robust welded stainless steel and offer either top or side entry for the electrical connection. The M12 mating connector is available in both a straight or right-angle version. The HS-100 sensors are industrial accelerometers offering a 100mV/g AC output with a top entry connection, whilst the HS-100S is a low profile unit with a side entry connection.

The HS-420 is a PLC accelorometer with integral circuitry providing a 4-20mA output proportional to the velocity level. The HS-421 model offers a dual output of 4-20mA for velocity and AC g suited for the many commercially available data collectors. For those needing to measure both vibration and temperature levels at the same monitoring point, Hansford Sensors has also introduced dual-output versions of the HS-100T (100mV/g output) and the HS-420T (4-20mA output) sensor models, both fitted with M12 connectors as standard.
