  • Transient Surges and Surge Suppressor Technologies: Comparing Apples to Oranges

    The suppressor to protect a specific point upon an electrical distribution system must be selected accordingly to its physical location.

    The sole function of a quality surge suppressor is to protect sensitive electronic equipment from transient overvoltages that are present on AC power circuits. It is irrelevant whether these overvoltages are generated by lightning activity or are induced upon the AC power lines by utility grid switching, power factor correction actions, power cycling of inductive loads, or from other sources. A quality surge suppressor must limit transient overvoltages to values that do not surpass the AC sine wave peak by more than 30% as it initially absorbs intense amounts of transient energy. The suppressor must immediately respond to transients before they reach their uppermost voltage values. Suppressor performance should not deviate or degrade with use when called upon to divert extreme levels of transient current.

  • Internet Access in a Process Control Environment

    Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether it's from the office or from the comfort of your own home. Today's PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics. With the latest PLC technology, almost anything that can be accomplished next to the machine can be accomplished wherever there is an Internet connection.

  • Industrial Ethernet… more than just another fieldbus system

    This whitepaper talks about how today Ethernet-based fieldbus systems perform basic task and so much more.

    As Ethernet continues to gain momentum in the industrial automation market, it's changing the way control engineers utilize their fieldbus systems. In the past, fieldbus networks were considered one-dimensional - they performed one task and did it very well - transferring process data between networked devices in a fast and deterministic manner. Usually these devices were on a local segment, isolated from higher-level networks. Nowadays, Ethernet-based fieldbus systems perform this basic task and so much more. With industrial protocols like Modbus/TCP, EtherNet/IP, and PROFInet process data is sent over standard, off-the-shelf Ethernet hardware. No longer are users forced to buy proprietary fieldbus components from a handful of vendors.

  • Increased plant safety puts focus on tank gauging

    The demand for safety technology in bulk liquid storage plants is increasing world wide. This market trend can clearly be seen in tank gauging projects where Safety Integrity Level (SIL) requirements are now being incorporated.

  • How are you tracking assets?

    Today the geo-location technology is mainly used within the supply management chain. In the process industry, these technologies can be used also for warehouse management as well as improving safety and work processes.
