IO-Link and connectivity in the age of Industry 4.0
Industry 4.0 will only become reality via standardised communication interfaces, since data and communication are key elements here. For this reason, IO-Link plays a prominent role with simple sensors, whereas Ethernet and Ethernet-based field buses are more prominent with sensors that are more high-performance and bigger.
Maximising bearing service life
Although every bearing has a pre-calculated service life, research has shown that two-thirds fall short of their potential lifecycle. Here Peter Townsend, product manager bearings at ERIKS, offers a 10-point plan to help customers get the most from their bearings.
Time to ride the wave of reshoring?
China’s slowing economy means it is time to jump on the wave of reshoring says Mark Anderson of Fascia Graphics.
Ten reasons for coding offline
Richard Pether, director at Rotech, explains why sometimes it simply makes sense to code offline, even for highly automated manufacturing and packing operations.
The differences between guarding standards ISO 14120 and EN 953
Jeremy Procter, a member of standards committees ISO/TC 199/WG 6 (Safety distances and ergonomic aspects) and BSI MCE/3 (Safeguarding of machinery), and Managing Director of Procter Machine Guarding, explains how the new edition of ISO 14120, the international standard for machine guards, differs from the standard it is replacing in Europe, EN 953.
How to use laser scanners correctly for machine safety
Dr Martin Kidman, a Safety Specialist with Sick UK, explains that selecting the correct safety equipment - such as laser scanners - will only get you half way to a safe machine; getting the rest of the way requires that the safety equipment is used correctly.
Why do drives fail?
A drive could theoretically last for a lifetime, but only if properly taken care of. Modern variable-speed drives (VSDs) are exceptionally reliable these days, but they are not indestructible. That said, if you notice similar persistent or repeated trips in a VSD, then chances are that the drive is not actually the problem. If such trips are ignored (eg overtemperature), they can sometimes result in the failure of the drive. Here we outline some of the primary factors that can contribute to why variable-speed drives trip and/or fail.
Designs for controlling hot processes – it’s all material
Angled seat process control valves form an integral part of process engineering in a huge number of applications and getting the right specification can boost reliability and productivity. One of the most important factors is temperature, both of the process media under control and the ambient temperature. Ian Webster, Hygienic Segment Manager for UK & Ireland at Bürkert Fluid Control Systems, looks at the impact that temperature has on valve design and how to achieve the most cost-effective solution.
