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 a very high standard.
SAW transducers: A better way to measure torque
Measuring torque accurately, particularly in rotating shafts, can often be challenging, but there is a reliable approach using technology based on surface acoustic wave (SAW) transducers, says Mark Ingham of Sensor Technology.
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
Nord solutions for the extended energy-efficiency directive
The European Commission has initiated a significant tightening of the energy-efficiency directive for electrical devices, leaving more users of drive technology faced with new challenges. By providing comprehensive information, fast, expert support, and suitable drive products, Nord Drivesystems aims to enable machinery and equipment manufacturers to continue producing economically compelling products that comply with all regulations.
Valves – when to repair or replace?
When it comes to process, pilot and actuation valves, the question of whether it is advisable to repair or replace a worn or intermittent unit is worth considering, regardless of the type or the size. Tom Carnell, Systems Applications Manager, from valve manufacturer Burkert UK gives his advice as a basic guide.
Clamping systems for precision down to the smallest detail
Whether its die construction, dental technology, medical equipment or the watchmaking, jewelry or optical industries – the number of high-precision applications for micro machining has risen enormously in recent years. Anyone who wants to take an efficient approach to delicate tooling, high spindle speeds and extreme requirements for precision must have clamping systems that offer stable processes.
Reliable data connections for Industrial Ethernet
Data is everywhere and an integral part of today’s control and process industries. There is nothing new about the use of data in industrial applications, but increasing volumes and real-time demands present real challenges for system designs. Planning for future system requirements is therefore an important consideration. Building extra capacity into a system for future needs starts with the architecture and is reflected in the component parts.
Advanced automation technologies in food manufacturing
The food manufacturers who are successful in today’s fast-paced, ever-changing industry are the ones who can capitalise on fast moving trends, optimise their efficiency and productivity, best manage their supply chain logistics, and minimise waste. Chris Evans of Mitsubishi Electric looks at how advanced automation technologies can help.
