Taking Another Look - The Value in Reassessing Old Solutions

Joe Ryan Sales and Marketing Manager at Precision Digital

During a period of economic slowdown, many process plants prepared for unfavorable economic conditions will use the opportunity to conduct much needed maintenance, repair, operations upgrades, and new installations. Upgraded process instruments (sensors, controllers, and other plant hardware) may only get considered at that time, due to holds on major new products. However, regularly evaluating your daily processes during normal maintenance and repairs can lead to immediate opportunities for improvement that can have a dramatic impact on the capabilities, efficiency, and effectiveness of a plant's procedures. Don't wait for something to break down before replacing outdated equipment when you can proactively modernize your process instrumentation.

Hazardous Area Classifications: What You Need To Know

Areas that have the potential for an explosion to occur are classified as hazardous areas and are regulated by multiple organizations and standards worldwide. These organizations are in place in order to ensure that areas that have the potential for an explosion to occur are maximizing the safety of personnel and limiting the possibility of property damage. This article will identify the agencies that regulate these safety standards, define the classifications of hazardous areas, and give examples of hazardous area devices including how to decipher the product labeling.

Back To Basics: Loop vs Line Power

The previous article in this series discussed loop-powered, or two-wire, devices. These instruments utilize the power supplied to the current loop to power themselves. A two-wire connection may not always be the most optimal power solution because of its inability to power devices that require a large voltage drop. Three and four-wire devices incorporate an external power supply in order to effectively eliminate the voltage drop placed on the process signal current loop. It is important to understand the differences between these three setups as they are fundamentally different and each has its own advantages as well as limitations. This article will define what a two, three, and four-wire connection is, discuss what the pros and cons are, and provide you with the necessary information for choosing the right wiring for your application.
