14/06/2012 - ABB electric drives save a record 310 million megawatt hours in 2011
Energy savings equivalent to the output of 31 nuclear power station blocks
About 310 million megawatt-hours (MWh) of electric power was saved by the installed base of ABB drives in 2011, an increase of 19 percent compared with the previous year. Electric drives are used to regulate the speed and power consumption of electric motors. Industrial electric motors account for about 25 percent of all the electricity consumed worldwide. |

30/05/2012 - Saving Energy with Tailored Drive Solutions
The reality of global climate change means that production and manufacturing techniques must become more modern and sustainable. The EU has already set the 20-20-20 goal as part of its Europe2020 strategy, with the objective of reducing carbon emissions by 20 per cent, lowering energy consumption by 20 per cent, and increasing the proportion of renewable energies by 20 per cent, all in order to curb climate change. From the manufacturing perspective, the term ‘sustainable production’ includes technologies able to make products with no greenhouse gas emissions, no non-renewable or toxic materials, and no waste – all while optimising profits and supply chain integrity.

18/05/2012 - Gravity and sensor calibration accuracy
How location, calibration and application influence the accuracy of inertial sensors.
By Mike Baker, Director, Sherborne Sensors
The calibration accuracy of many sensors is fundamentally dependent upon the force of gravity at the site of operation. Examples of such sensors include accelerometers, inclinometers, force transducers and load cells. Consequent upon the principles upon which these sensors work, their sensitivity is fundamentally proportional to the force of gravity where they are being used; their absolute sensitivity may well differ when in situ from that of their place of manufacture. The acceleration due to gravity varies across the Earth’s surface due to a number of circumstances and, in the extreme, may well translate to a variation of up to 0.5% depending on where in the world it is measured. |

15/05/2012 - Selecting Position Sensors in High Vibration Environments – the Do’s and Don’ts
Machines that are subject to harsh or prolonged vibration present challenges for many components – none more so than position and speed sensors. In this article, Mark Howard of Zettlex, lists 10 simple rules for design engineers when selecting position and speed sensors that must cope with shock or vibration.

02/05/2012 - Don’t judge a load cell by its cover – appearances can be deceptive!
Introduction
Strain gauge load cells are the life blood of modern, high performance industrial weighing systems, playing a particularly important role in weighbridge systems. Despite the harsh operational environments weighbridges encounter (extreme temperatures, ice, snow, wash-down, flooding, excessive braking and minimum maintenance), the load cells are expected to provide exceptional reliability and accuracy. |

28/03/2012 - Living in a material world...How to decide which material type is best suited to the enclosures for your application.
A quick online search for electrical enclosures shows just how many options and variations there are on today’s market;there is a myriad of apparent choices for material and each seems to offer unique benefits and features.It can be hard to pin down the enclosure type that is best for your application, both in terms of performance and cost,so what are the key considerations when specifying an enclosure’sconstruction material; and how can you be sure that the products you choose will meet the application’s requirements?

27/03/2012 - The future of load cell weighing
Introduction
Weight (or more correctly Mass) is one of the three fundamental measurands, together with Length and Time. Its accurate measurement is vital to the world we live in, providing important controls in manufacturing, trade and commerce. So how has it changed over the years and what does the future hold? |

20/03/2012 - IHS Product Stewardship Experts Advise Companies to Treat GHS as a Strategic Business Challenge to Reduce Risks, Complexity
ENGLEWOOD, Colo. (March 15, 2012) – IHS (NYSE: IHS), the leading global source of information and analytics, recommends companies begin aligning their business processes to comply with the Globally Harmonized System of Classification and Labeling (GHS), which will be adopted by the U.S. Hazard Communication Standard (HCS) by the Occupational Safety and Health Administration (OSHA) later this month.

14/03/2012 - DO YOU KNOW HOW MUCH YOU ARE AT RISK?
Stuart Jaycocks, Strategic Marketing Manager, Weidmüller Limited, takes a look at Standard BS EN 62305
Electronic systems now encompass almost every aspect of our lives. The use of computers, electronic process controls and telecommunications has increased dramatically over the last two decades. Not only are there more systems in existence, but the physical size of the electronics involved has reduced considerably – which means that their circuitry can be easily damaged by lower levels of energy and power surges. |
