MTS has released absolute linear-position sensors, which are now available as versions approved for installation in hazardous areas. The explosion-proof versions of the Temposonics R- and G-Series position sensors are suitable for use in a potentially explosive atmosphere containing flammable gases (groups IIA, IIB and IIC) and dusts.

An independent test body certified the sensors in compliance with the European ATEX directive 94/9/EC. With above-ground applications, the position sensors meet the requirements of instrument categories 3D (Zone 2) and 3G (Zone 22). When the sensors are operated in these zones, although the atmosphere presents the corresponding explosion risk, there is no hazard of inflammation.

The transducers are available with rod- or profile-shaped housings and analogue, CAN, SSI or Start/Stop interfaces. The maximum surface temperature is 135C in a gas-containing atmosphere and 100C if dust is present in the environment. Various protection types preclude the position sensors from being a source of inflammation when operating inside an explosion-hazarded atmosphere.

When installed in hazardous areas containing dust, the airtight sensor housing ensures that the operation remains safe. The IP67-rated housing protects the sensors against ingress of dust and water. As the formation of sparks during operation is prevented, the transducers can be operated securely in an atmosphere containing gas.

As a result of the ATEX approval, the field of application of the non-contact, wear-free Temposonics linear-position sensors is extended. Explosion-protected versions are now safe for measuring applications in hazardous areas, such as paper-, textile- and wood-processing industries, for power generation and energy supply, as well as in the paint industry and for gas turbines.

IFM Electronic has launched the AC007S module, designed to connect safety devices such as fail-safe sensors and light curtains to the safety version of ActuatorSensor-Interface (AS-i).

Ideal for use with IFM Electronic's safe proximity sensors, the SIL3-compliant AC007S module takes OSSD (output signal switching device) signal input from a sensor or other ESPE (electrosensitive protective device) and checks the integrity of that signal for cross faults, for example, as well as the switching status of the ESPE and its own internal integrity and transmits this data via As-i Safety at Work.

Overall safety is ensured on the AS-I Safety at Work system by the safety monitor, and the safe data transmission on the AS-i bus has been approved by TUV and BIA.

It is suitable for signal transmission up to the highest category 4 to EN 954-1 and IEC 61508 / SIL3.

IFM's IP67-rated AC007S safe input module can be field-mounted along with other standard or safe devices on the AS-i cable, which supplies power for the unit in addition to bus signals.

The AC007S features bright LEDs for visualisation of signal states or possible faults, while connection to the input can be via industry standard M12 connectors or cage clamp terminals.

VKI's knowledge of environmental and applied fluid dynamics, wind technology, measurement techniques and flow phenomena simulation will help LMS develop and validate methods and software technology.

In the aero-acoustics field, these activities cover heating, ventilation and air-conditioning projects, whereas fluid-structural interaction applications are useful in wind noise transmission research.

Kew Technik has introduced a telescopic pole that lets users make safe contact with exposed conductive parts on electrical equipment such as fluorescent luminaries, fans and air-conditioning units. The hollow pole can be extended up to 5.6M in length.

It is available with or without an R2 test probe, which can be quickly fitted to the end of the pole, removing the need for ladder towers or scissor lifts. The telescopic pole has a polyester resin-baked coating for added durability.

Migatronic has added two models to its range of super compact, mono-phase Delta welding machines, both of which can weld thicker plates than the three present Delta machines. The Delta 200 HP TIG/MMA machine features a pulse function and high output in the current range 5-200A, while the Delta 180 E MMA machine operates in the current range 5-180A.

The increased power has no effect on the weight: Delta 200 HP weighs 10.7kg and Delta 180 E weighs 9.5kg. In addition to assembly and repair jobs, the two machines are also suitable for workshop use. With casings of aluminium and plastic available, the operationally reliable welding machines are both portable and sturdy.

With the scratch ignition, the Delta 180 E MMA can also be used for simple TIG welding. The welding machine features hot-start, arc power functions and protection against fluctuations in the mains voltage, and the welder has the option of a plus or minus pole on the electrode clamp. The Delta 200 HP machine features operational comfort and is ideal for quality welding of stainless steel, mild steel and all other DC-weldable materials.

In TIG welding, with or without pulse, it is possible to use up to 3.2mm tungsten electrodes and in MMA welding, the machine welds with up to 3.2mm covered electrodes. Two-stroke or four-stroke TIG with HF or LIFTIG ignition are optional functions. Delta 200 HP features arc control and variable gas post-flow, and in both TIG welding and MMA welding, the machine can be operated through a remote control unit. The set welding current can be read on the digital control panel.

Tekscan has released the High-Temp Flexiforce Sensor HT201, which can measure forces in environments as hot as 200C. The ultra-thin, highly-linear (typically +/-1.2 per cent) High-Temp Flexiforce sensor is ideal for non-intrusive force measurement in a variety of processing applications, including injection moulding, heat sealing and heat-sink applications.

Industries that will benefit from these high-temperature force measurements include automotive, aerospace, pharmaceutical, printing and food and drink processing.

The sensor can: detect and measure a relative change in force or applied load; detect and measure the rate of change in force; identify force thresholds and trigger appropriate action; and detect contact and/or touch. The HT201 sensor is available in two force ranges, low and high.

Airborne Composites has bought Fibersim software from Vistagy to reduce lead times for new products by 20 per cent and for redesigned and scaled versions by more than 30 per cent. Airborne Composites will begin by using Fibersim to design and tool the composite overhang panels for the empennage wing surfaces of the Gulfstream G650 business aircraft.

The panels are a sandwich structure comprised of carbon fibre/epoxy skins and a honeycomb core. Airborne Composites is subcontracting for Stork Fokker on the G650 programme. The biggest challenge Airborne Composites faces with the G650 programme is short lead times and the need to make quick design changes during definition of tooling, plies and processes.

Wiard Leenders, general manager of Airborne Composites, said: 'Fibersim is completely integrated into the Pro/Engineer Wildfire CAD system and allows for redefinition of the CAD part while defining the plies, which enables our engineers in analysis and design to work in parallel and deliver designs faster. 'The software simulates how fibres deform when draped over a complex curvature, giving us the information we need to accurately define plies on the first iteration.

'Furthermore, Fibersim's export and documentation capabilities give us the ability to quickly create clear instructions and export flat patterns to laser projection and cutting software. 'Our products require accurate ply definition and layup so engineering can be done quickly. 'Fibersim enables us to accomplish this by generating this data in a controlled and efficient manner.'.

Carlo Gavazzi has introduced a range of compact radar sensors for automated doors, lifts and escalators, which offer intelligent detection and simple, flexible installation. The RAD01 and RAD02 radar sensors utilise Doppler shift in a K-Band (24,125GHz) signal to detect motion towards or away from the device and provide SPDT relay output, which operates the door. Sensing is bidirectional in the case of the RAD01 and bi/unidirectional for the RAD02, enabling the latter to detect motion towards and away from the device.

The radar sensors are compatible with all types of domestic and commercial automatic door, including sliding, swinging, folding, revolving, and overhead doors. They can also provide access to lifts and for automatic starting of escalators. Housed in glossy or translucent black polycarbonate, the new devices require a small 118 x 80mm footprint and weigh just 150g. Built-in microprocessors compensate for the effects of temperature and atmospheric conditions and also filter-out external RF signals.

Immunity can be adjusted to prevent false signals from leaves, rain or snow, which can cause problems when IR sensors are used. The RAD01/02 sensors provide quasi-presence adjustment, enabling the detection of slow-moving people, reducing the possibility of doors closing prematurely on people with limited mobility. Motion can be detected from 0.05 to 1m/s. The use of a flat planar antenna, with installation adjustment in all three dimensions, ensures precise orientation of the activation pattern.

The centre line can be adjusted between 15 and 45 degrees forward from the vertical and 15 degrees left or right in the horizontal plane, providing pattern detection from 0 to 90 degrees vertically and +/-30 degrees horizontally. Sensitivity, relay hold-time and immunity detection can all be set via buttons on the control board or using an optional IR remote control. The RAD02 can also be set for unidirectional or bidirectional operation.

PCB buttons allow the relay to be set or active (NO) or passive (NC) operation and the infrared controller can be used to switch between automatic, permanently open and permanently closed states. The unit's status is displayed by an LED visible 180 degrees around the front. Power consumption is less than 0.5W from a 12-24V AC/DC, 50-60Hz supply. Clamp terminals ensure quicker installation than devices that use screw terminals. The sensors also benefit from RoHS, CE, cURus and FCC approvals.

Sprint Electric has brought out digital DC drives that function up to 1850A (800 KW/1080 HP). The digital DC drives are available in two-quadrant and four-quadrant options.

ICP DAS USA has announced the launch of the NS-205PSE, a compact, five-port, unmanaged Ethernet switch that connects network elements while supplying up to 15.4W of power per port. Each of the ports supports 10/100Mbps speed auto-negotiation while the device offers 3.2 Gbps of high-performance memory bandwidth, so it can handle some traffic.

The NS-205 transitions between different configurations with its auto MDI/MDI-X crossover technology for plug-and-play adaptability. Other notable features include fully duplex IEEE 802.3x and half-duplex back-pressure flow control to avoid data interference, store-and-forward architecture and IEEE 802.3af compliance on its four power-over-Ethernet ports.

The NS-205PSE has both auto-detection of powered devices and automatic power management. The unit can operate within a temperature range of -30C to 75C, sports over-temperature, over-current and over/under-voltage detection and is robust. Its LED indicators allow users to quickly monitor its state.

Parker Hannifin has launched a range of air filters that incorporate aerospace technology for optimised air flow and more efficient filtration. As a result, the Moduflex Extras filters can reduce energy costs and help organisations minimise the environmental impact of pneumatic applications. The flow management system uses a number of features based on aerodynamic principles, allowing flow rates to be increased.

These features include a 'bell mouth' inlet, which provides an unrestricted path for air entering the filter element, and a smooth elbow that directs air into the filter element more efficiently than the sharp 90 corner inside most conventional filters, said Parker. Many of the models in the range feature specially designed turning vanes, which channel the incoming air to reduce pressure drop and further increase efficiency.

The Moduflex Extras filters feature deep pleat element technology and specially treated filtration media to offer 400 per cent greater surface area than traditional wrapped filter elements, resulting in increased dirt holding capacity and extended service life. The coalescing filters in the range use four drainage features to ensure high performance.

These are a high-efficiency layer that provides increased liquid drainage; a specially designed element underneath the lower end cap to eliminate 'wet band'; drainage ribs cast into the filter bowl to allow liquid to drain more rapidly; and surface tension breakers moulded into the lower end cap to prevent liquid from sticking.

A range of accessories is available for use with the filters including an incident monitor to indicate premature high-differential pressure; a fixing clamp for quick and simple connection of multiple filter housings; and mounting brackets, which provide additional support to filters installed in flexible piping systems or OEM equipment. The Moduflex Extras filters have passed testing in accordance with ISO 12500 and have been independently verified for performance by the Lloyd's Register.

Trelleborg Automotive has developed a damping plate that allows PSA Peugeot Citroen to reduce noise and vibration caused by diesel-engine knocking. Trelleborg Automotive used its NVH experience to produce a specially-cut shear plate, engineered using the company's Duru-LAM material.

Resistant to both heat and oil, Duru-LAM is a proven material for damping sound and vibrations in internal engine applications and, in the shear plate design, it comprises a layer of rubber sandwiched between two layers of steel. The shear plate is then positioned according to the packaging requirements of different core engine designs and can be used in gasoline, as well as diesel variants. Arvid Norberg, research and development NVH manager at Trelleborg Automotive, said: 'The conventional solution to reduce vibration is to increase engine block stiffness, but in many cases this only shifts the noise to higher frequencies.

'The introduction of the shear plate enables us to reduce vibration and noise levels, resulting in improved sound quality.' Since receiving shear-plate prototypes from Trelleborg Automotive, PSA Peugeot Citroen has undertaken rigorous acoustic research and simulation testing of the part and has developed a technique that enables ranking of engine sound quality. Leon Gavric, senior acoustics expert and head of PSA Peugeot Citroen's Powertrain NVH Department, said: 'The shear plate filters out unwanted vibrations and knocking noise, but the real gain is that by reducing noise and vibration issues, we can tune the combustion to reduce emissions, pollutants and fuel consumption.

'As a result, it makes designing higher-performance eco-friendly engines a reality.' Trelleborg Automotive also expects its shear plate concept to deliver additional cost savings, by reducing the need for other, more expensive and heavier damping solutions. The company is undertaking further damping tests with its Duru-LAM material, using FEM tools to determine thickness measurements and shear-plate tuning requirements of different engine types. In addition, Trelleborg Automotive's shear plate concept is expected to assist manufacturers upon the introduction of new European emission standards, Euro Five and Euro Six.
