21/08/2013 - Manufacturing sector is too focused on quick, easy energy wins rather than looking at the bigger picture, believes James Palmer at IMServ
Accurate measurement of energy usage is the key to energy savings

22 July 2013, Milton Keynes, UK: The UK industry consumed 320TWh of energy and emitted 95 million tonnes of carbon dioxide into the atmosphere. This figure represents around 17% of the UK’s total energy use, with most of these emissions coming from manufacturing1. According to James Palmer, Regional Sales Manager at IMServ, one of the UK’s largest independent energy data management providers, the manufacturing sector has been too focused on implementing easy and low cost energy saving initiatives rather than looking at the bigger picture.
 
14/08/2013 - Priceless ceramics
Stray electrical current can rapidly reduce bearing lifespan and inflate maintenance costs. If you are concerned about the effects of electrical discharge, it may be time to start investing in ceramics, says Phil Burge, Communication Manager at SKF.
 
06/08/2013 - Why Use an AC-Operated vs. DC-Operated LVDT Linear Position Sensor?
When initially introduced fifty years ago, all LVDT linear position sensors were AC-operated and required external oscillators, carrier amplifiers, demodulators and filers to operate. 
 
01/08/2013 - Common sense
Vibration sensing has become an increasingly common tool in the process industries, enabling engineers to detect exactly which components are due to fail and when, and thus facilitating the efficient replacement of parts. Chris Hansford, Managing Director of Hansford Sensors, explains how the use of vibration monitoring solutions keeps production lines running smoothly in a range of applications.
 
29/07/2013 - Why choose Absolute over Incremental Position Sensors?
For position sensing applications, many engineers are still specifying incremental sensors because they believe absolute versions are too complex and/or costly. Darran Kreit, Technical Manager at Zettlex, describes the two approaches and compares the relative benefits of each.
 
17/07/2013 - HOW TO SELECT THE BEST COUPLING FOR …
True angular misalignment

The common causes of true angular misalignment are when one of the connected shafts is compliantly mounted; for example, when it is located by a self-aligning bearing.
 
16/07/2013 - Less is More : Why You Should Pump Slurries with a Peristaltic Pump
• LESS WATER
Peristaltic Pumps Use Less Water

Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 75 tonnes of ore per hour and at 65% solids, every time a hose pump replaces a process slurry pump, it saves over 1,100 Million litres of water annually because of the slurry pump’s inefficiency : on the same duty, the hose pump requires less than 25% of the process water of a slurry pump
 
11/07/2013 - A BETTER WAY TO MEASURE TORQUE
Measuring torque accurately, particularly in rotating shafts, can often be challenging, but new technology is providing a better solution, says Mark Ingham of Sensor Technology.
 
08/07/2013 - Direct versus Indirect measurement of shaft angle
As a rule, it’s preferable to measure directly the position or speed of the object that you are interested in. In many cases, practical problems of physical environment or limited space mean that this can be a challenge, particularly when measuring the angle of shafts with a diameter greater than a couple of inches. The traditional approach is to measure angular position or speed indirectly – typically inferring the shaft’s position from measurements made elsewhere. Mark Howard of Zettlex Ltd describes the traditional approach and a new, direct approach enabled by inductive sensors.
 
01/07/2013 - Non-Destructive Testing - how far should you go?
Every day millions of components are produced around the world to help build everything from a simple toy to fighter jets. For every manufacturer involved in the process, a decision must be made on how to test the component to ensure it meets the design criteria. For the vast majority, batch inspection and testing is sufficient, however, where high precision engineering is involved the testing must be exhaustive and comprehensive. Components for aerospace, motorsport, medical devices and other ultra critical areas are required to be tested to an extremely high standard.
