After years of delays the API 682 4th edition was finally released this past May, signifying a change to transmitters instead of switches for monitoring seal support systems. As the 4th is not a mandatory requirement, which standard, 3rd or 4th edition, should you deploy? Here are a few things to consider before you decide.

Without knowing the capabilities of old and new technologies, it’s highly likely that the wrong selection will be made. Understanding SIS and the pros and cons of mechanical switches, smart switches, and safety and process transmitters will help to make the appropriate choice.
Electric control valve actuators for this type of application require certification for hazardous environments as well as a robust enclosure. They must also have the ability to constantly adjust valve position to accommodate a changing flow rate from the well.

Safety monitoring software and smart field devices can improve safety system performance and operation. The white paper describes how to use safety monitoring software to distill the data from smart field devices and other sources into easily understood and actionable information that can improve the operation of the safety system.

More components in microprocessors eliminates the need for additional external automation components, such as data loggers, math co-processors, communication cards, PID controllers and more. White Paper explains how consolidating functionality into fewer components creates lower costs and power usage for the total system, while providing easier integration and greater reliability.

When combined with a risk reduction process to eliminate, reduce, or otherwise address the risks, an organization can demonstrate that appropriate measures have been taken to suitably reduce the risk, while also ensuring that the measures applied are not grossly over dimensioned for the level of the associated hazards.

There is a lot of focus on flue gas analyzers, but it’s also important to remember that an analyzer is only as effective as the sensors it uses. Because of the risks associated with combustion emissions, sensor safety and reliability are critical.

When heat transfer fluid (HTF) accumulates carbon residue and coke builds up on internal surfaces, it can lead to fouling, overheating, thermal cracking and choked pipes, creating a fire hazard. Here’s how to maintain thermal fluids and thermal fluid systems.

Having a redundant Ethernet network is important to W&WW management, because many plants are still legacy, meaning they were either built with a stand-alone station or have a traditional star topology Ethernet network.

Organizations who use technology for applications that are not fit-for-purpose often find themselves starting, stopping, re-grouping and re-starting projects. This article demystifies what goes where (ERP, MES/MOM, Controls) and provides practical examples to guide companies through the decision making process.
Most safety standards provide guidance for the entire lifecycle of machinery to enable them to remain safe. There is no one ‘right’ choice for every organization when selecting standards to follow for implementing safeguarding measures. There are, however, choices which are clearly wrong – such as not doing anything.

Harmonics is a major concern in many applications today. The increased use of variable frequency drives introduce more energy efficient systems but also an increased harmonic loading. In this paper a number of compensation techniques are discussed.

An electronic workforce of process robots can count your inventory items in real time, on demand, with no mistakes made. You pay them nothing, and they never complain. They even alert you to any issues related to orders, inventory levels, or shipments, taking action to reorder items when they drop below minimum thresholds.

Enterprise Automation & IT has been run for decades by professional IT and Automation managers that understand basic IT security. However, guidance from the industrial automation industry is fragmented and scant in regard to improving cyber security of control systems. lndustrial cyber security experts are peddling their rehashed wares, trying to cash in on clients fears, ‘Y2K’ style. Here’s a look at the standards, efforts and problems with industrial cybersecurity.

Limit devices provide vital protection for temperature controlled process systems, ensuring product quality and the safety of both the workforce and the plant itself. This paper takes a closer look at why limit devices are required, describes how they work and explains why they reduce risk, providing a useful summary to anyone who is
considering specification of limit devices.
Built to Last: Maintaining Reliability and Uptime of Critical Connected Systems in Industrial Settings
By Tim Senkbeil, Lumberg Automation
Businesses in industrial settings require cabling components that are built to last, and can be depended upon. This white paper outlines the specific challenges connected systems face in extreme industrial settings, the benefits of new solutions that help maintain uptime, and steps and strategies for finding the best products.
Manufacturers are integrating commercial PC technologies to provide the customized solutions that users demand.

Overall Equipment Effectiveness shows where operational losses are and should be used in lieu of an incremental-only budget. OEE information indicates every place that product value can be found, and therefore sheds light on where to apply precious resources.
Expansion of engineering materials is a common issue, but not much is known about how expansion affects the repeatability of positioning equipment. This white paper discusses and tests that effect.

White Paper describes how one or more multi-function safety relays can often be used to replace many basic single-function safety relays, simplifying installations and saving money. In many cases, multi-function safety relays can be used instead of a safety-rated PLC, resulting in substantial savings while streamlining implementation and maintenance.
