New carrying accessories make enclosure range even more portable
OKW has added a range of accessories for its CARRYTEC range of portable enclosures which are well suited for portable instruments and test equipment. The new accessories include two new soft storage and protection bags, left and right handed, which are designed for car- rying equipment cables, test probes, sensors and tools etc.
The bags clip on to the side of the enclosures and have an opening next to the underside control panels on the enclosures. This allows the cables to be connected to the equipment and stored in the bags for use when needed. The bags have a zip opening and separate storage compartments. A new shoulder strap is also available which fits to the
bags so the equipment can be easily carried by the user. CARRYTEC enclosures feature an inte- grated handle and are available in three standard sizes with external dimensions of 222 x 205 x 80mm to 348 x 303 x 117mm. Two standard materials are available - ABS (UL 94 HB) in off white (RAL 9002) for indoor use, and fibreglass reinforced polyamide (PA GV) in lava grey for tougher outdoor use. An IP54 sealing kit is also available as an accessory. The enclosures are easy to assemble and the top section has a recessed area for membrane keypads, displays and touch- screens. Inset flat sections on the under- side are designed for mounting connec- tors or control switches. Screw pillars are provided in the top and bottom for fitting PCBs, displays and assemblies. Other accessories include battery com-
partments for five 1.5V AA cells and a med- ical holding clamp for round tubes or rails. OKW can supply the CARRYTEC enclo-
sures fully customised with additional holes, silk screen print legends and logos, and EMC shielding on the inside. OKW

Versatility added to UPS range
Power management company Eaton has added new 3-phase models to its Eaton 9PX range of compact high efficiency UPSs. Available throughout the EMEA region, the new models are well suited for IT and industrial appli- cations where a 3-phase power source is conveniently available and outstanding energy effi- ciency is a prime requirement. The new 3-phase in, single- phase out (3:1) models in the 9PX range are offered with power rat- ings of 6, 8 and 11kVA, with all versions incorporating a mainte- nance bypass for easy replace- ment of the UPS without powering down critical systems. They complement the existing 9PX single-phase (1:1) models, which are available with ratings from 5kVA to 11kVA.
A key feature of all UPSs in Enter 249
Eaton’s 9PX range is the energy efficiency, which enables users to reduce energy usage and cost. When operating in double con- version mode, the UPSs achieve an efficiency of up to 95% and, when mains power quality is good, this increases to 98% in

Cirrus Research Helps Ilmor Engineering Overcome Noise Issues
A
s one of the world’s top racing engine design and manufacturers, noise levels in the workplace have always been an issue for Ilmor Engineering. But when they won a large contract with the US giant General Motors to design and manufacture a new turbo-charged V6 racing engine for the 2012 IndyCar championship,
its managers knew
immediately this would result in significantly increased production as well as noise levels across the manufacturing and testing departments. At the time, the company’s existing noise management system split the factory into ‘Zones’ based upon the noise exposure levels. The main machine shop was mostly Zone 0 – or where noise levels are below action level 1 / 80dB(A). The new contract meant additional machine tools had to be installed in the main machine shop adding to the noise background levels. These additions also speeded up the production rate but had the potential to ‘tip’ some of the machine operators working in Zone 0 or exposure above 80dB(A).
Nick Phillips, Ilmor Engineering’s Manufacturing Manager explained: “When employees are loading and unloading work into the machine, an air gun is used to blow the
swarf and excess cutting fluid from the machine. This generates very high levels of noise, albeit of short duration, so hearing protection was used by our operators to control their levels of exposure to noise.” To determine whether Ilmor Engineering workers were being exposed to noise levels above 80dB(A) a repeat occupational noise exposure survey was carried out using a Cirrus Research doseBadge. “The doseBadge is a wireless personal noise dosemeter, ideal to be used to carry out noise measurements in occupational and industrial hygiene and so provide a unique solution to these applications,” added Nick. By using a doseBadge, accurate measurements and recording of employees’ long term exposure to noise were tracked and analysed as that poses the greatest risk to an employees’ hearing and physical state. The doseBadge can be set up to meet almost every occupational or industrial hygiene noise measurement standard, as well as EU Physical Agents Directive and the 2005 Control of Noise at Work Regulations (UK).

high efficiency mode. To make them easy to manage, 9PX UPSs feature a large graphi- cal LCD screen that provides real time information about operating status and offers easy access to analytics and configuration capa- bilities. The units also incorpo- rate a sophisticated control system that, in double conversion mode, continually monitors power conditions and regulates the operation of the UPS for opti- mised capacity management. Remote monitoring options are provided by Eaton’s Intelligent Power Manager Software, which is supplied as standard with every 9PX UPS. The UPSs are compati- ble with all major operating sys- tems and virtualisation software which aids easy integration. Eaton
