Understanding Arc Safety Can Save Lives
Arcs are a too-common by-product of working with live equipment. They have the potential to kill, but workers can be protected.
Arc faults have been creating damage for more than a century, but interest in preventing injury caused by arc explosions in high voltage environments is on the rise. OSHA is getting stricter about enforcement, and awareness of the potential danger is growing.
In 2007, the Occupational Safety and Health Administration adopted NFPA 70E-2000 into the Regulations (Standards 29CFR) under Part 1910 Occupational Safety and Health Standards, Subpart S, a document developed by the National Fire Protection Association. In 2007 the standard, NFPA-70E was put on a three year revision cylcle with 2009 being the latest revision. A central part of that 98-page book addresses arc faults and arc blast safety... Read more
The Five Easy Pieces of Network Installation
Breaking network installation into segments makes the job easier to manage
Setting up an industrial network and getting it running is one of the most critical aspects of modern factories. But this complex task can be easier to manage when it's broken down into manageable tasks.
In most applications, the job can be segmented using the five steps common to many industrial projects. Design is the first, and it's generally the most time-consuming since it sets the stage for those that follow... Read more
RFID Moves into Higher Gear
Move to UHF brings benefits, but has many challenges
The RFID technology that's made solid inroads into industrial applications in recent years may undergo a significant change over the next few years. UHF technologies that are being used in the supply chain by groups as diverse as Wal Mart and the Dept. of Defense may be moving into the factory.
High frequency RF tags have gained acceptance in automation systems based on their technical benefits. HF tags work better than UHF tags in environments where there's spray or other usage of water. Their performance around metal is also more predictable, so there's a higher chance that HF systems will perform flawlessly over time. Add in larger data capacity, and HF seems a logical winner in factories... Read more
