PRODUCTS AND SERVICESGreenbank monitor for ChinaThe Greenbank Group has announced it haswon a commercial contract with DatangGuiguan Heshan Power Generation Co. Ltd,one of the largest power generationcompanies in China. Greenbank will besupplying its G-CAM Carbon-In-Ash Monitor,an on-line analyser which uses cuttingedge microwave techniques to measure the amount of un-burnt coalremaining during the power generation process. Greenbank’s G-CAManalysers will be installed and commissioned on two of the HeshanPower Station’s coal-fired boilers early in 2011.www.greenbankgroup.comNew Boltight valve offers improved safety advantagesBoltight, a global leader in bolt tensioning systems, says it is findingmore customers are opting to have an integral tamper proof pressurerelief valve fitted to air pumps supplied for bolt tensioningapplications. The Boltight safety valve is a cost-effective way of minimisingthe risk of equipment failure during tensioning. It is fitted tothe high- pressure system. The benefit of fitting pressure reliefvalves to air pumps has been highlighted by a number of incidents inthe industry. Incorrect use of bolt tensioning equipment or inadequatetraining can sometimes lead an operator to build up excesspressure in the system when manuallytensioning a bolt to precise measurements.With a safety valve fitted to the systemthe pressure cannot increase beyond a safeoperating level.www.boltight.comRugged computing power in the energy field from JTLRuncorn-based JLT Mobile Computers, is reporting a significant boostin sales over the last year. Figures show an increase of 50 per centreflecting the demand for the company's class-leading rugged mobilecomputers. JLT's tablet PCs and in-vehicle / fixed-mount PCs areused in a wide range ofdemanding and harshenvironments.Some of the recentapplications of JLT devicesinclude integrating touchscreen PCs into nondestructivetestingequipment, and directinstallation in field servicevehicles while tablet PCsare providing the mobile computing power required by industry."Our rugged products present an excellent return on investment forend users. JLT has been developing rugged PCs for the power industrywhich demands the highest levels of reliability and ruggedness,"comments company Mark Muslek.The JLT fixed-mount PCs incorporate an aircraft-grade aluminiumchassis with a high-tech outer casing that resists chemical attack andprovides a waterproof and dust proof seal. All models in the rangeare subject to strict testing including water-sealing tests up to IP67,humidity, vibration, shock and exceed MIL STD 810F.www.jltmobile.co.ukNew cover for plug & socket connections from AUMAdesigned for actuators & controlsAUMA Riester GmbH & Co. has developed a new cover for plug andsocket connections for its electric actuators and controls used forvalve control in the power industry.The S-105 cover provides more space for cable gland/conduitassembly. Increased interior capacity makes cable connection easierand accommodates thicker cabling. Based on AUMA’s modularactuator design philosophy, the cover - which is 15 mm higher thanthe company’s previous model - is fully compatible with itsprevious version, ensuring that early generation products can beincorporated. As standard, AUMA actuators are equipped with aplug/socket connector for motor and control cables.AUMA reports that the significantadvantage of thistype of connection is that,once connected, wiringremains undisturbed, evenif the actuator has to beremoved from the valve,e.g. for maintenancepurposes. The new plugcover is designed for allAUMA weather-proof andexplosion-proof actuatorswith or without controls.www.auma.comNew Chromalox cable gets Fm & CSA ratingsChromalox’s Mineral Insulated (MI) Heating Cable has achieved aseries of major global certifications, including CSA, and FactoryMutual. Chromalox MI Cable uses the highest grade nickel-alloy metalsheath to enable the cable to maintain temperaturesup to 1100 degrees F, making it ideal for the alternativefuels & power generation industries. Chromalox MIcable is suitable for applications where operating temperaturesare too high for plastic cables, such as steamlines used in power generationwww.chromalox.comNw test terminal disconnect blocks from PhoenixThe new ME test disconnectterminal blocks from PhoenixContact provide safe disconnectcapability between measuringtransducers and safety equipmentin current transformer (CT) shortingapplications. The screw-freedisconnect lever provides visualindication of the switch’s position.Designed for use in such industriesas power generation, utilities andsemiconductor manufacturing, theME terminals can be used wherever high currents must be reducedusing current transformers, and where high voltages are reduced withvoltage transducers.
