A dangerous misconception exists regarding the "Arc Rating" of infrared (IR) windows or viewing panes. Many reliability and maintenance professionals are under the impression that an IR window will protect them in the event of an arc blast. Others believe that installing IR windows will turn non-arc-rated switchgear or electrical equipment into "arc-rated" cabinets. Neither is true. Both misconceptions need to be corrected because they present safety concerns.

Soft foot is one of the most prevalent conditions found in rotating machinery. This condition, if not corrected, makes an alignment job much more difficult and sometimes impossible. If the internal alignment is not correct, the external alignment will not matter.

Your company has recently purchased a laser based alignment system. Your newly trained technicians are asked to align a critical process pump. You witness the alignment. They save the final alignment data. You review the data, but what does it mean? How does it compare to dial indicators? Why did they rotate both shafts when measuring the misalignment? Why are the numbers at the feet higher than you would like? How do you KNOW the alignment is good? The debate begins.

Lubricated machines require clean, dry oil to work properly.

Holistic pump system designs optimize system efficiency and life cycle performance.

On July 16 last year, a high-speed centrifugal pump failed catastrophically at a large refinery in South America, causing production losses and costing a substantial amount of money for repairs. The inboard bearing of the pump lost lubrication, overheated, and seized up.

Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

How a monitoring alarm system with control and shutdown capabilities prevented costly pump damage and environmental hazards and made the job of the pump operator safer and easier.

The 4-20mA current loop is used to transmit analog data representing various process variables like level, pressure, temperature or flow. Although conceptually simple, a 4-20mA current loop can be tricky to troubleshoot. Current flows in a single direction through each device in the loop.

Increased efficiency, higher air handling and fast, automatic priming are provided with new technology.

In the oil and gas industry, custody transfer transactions involve transporting physical substance from one operator to another, including transferring raw and refined petroleum between tanks and tankers, tankers and ships and other transactions. An accurate account of the amount of material transferred is of great value to both the company delivering the material and the eventual recipient. This is especially true in bunker fuel oil delivery since a ship's bunker contributes to the ship's operating cost.

Data and life cycle management technology helps refineries maintain equipment and reduce the total cost of ownership.

Growing infrastructures are creating more complex problems for municipalities than ever before, forcing them to search for a diverse range of system solutions to issues involving energy savings, maintenance savings and total life cycle cost analysis.

Starting can have a significant effect on the life of the winding insulation of an AC motor.

Enveloping is a tool that can give more information about the life and health of important plant assets. It is primarily used for early detection of faults in rolling element bearings and gearboxes. Enveloped acceleration is an especially valuable parameter to trend, as the progression of machine condition can be evaluated. Armed with good information and assisted by service experts, plant engineers can be confident in the proper operation and management of the important assets in their care.

Most VFD systems use some form of closed-loop feedback to avoid surging, excessive noise, and in extreme cases, vibration. A reliable encoder signal is one method that minimizes speed variance and helps eliminate these unwanted effects. Here's how it works.

The past may be prologue to the future, but the time between the two seems increasingly short. In the past, labor, capital and raw materials were considered the underpinnings of wealth creation. Today, real-time process knowledge and innovative management strategies have become far more important for creating value, as evident in the headlines above. Accordingly, the time for systemic change is now. . . the opportunity to reinvent industrial manufacturing and the products and services that surround it have never been greater since the beginning of the industrial revolution.

A recent marketing survey found that 84.0 percent of satisfied customers would "jump ship" for a better deal if an opportunity arose. With markets becoming increasingly globalized, customer retention has become a critical part of business strategy. Companies need to ask themselves: What reason can I give this customer to stay, even if my competitor offers a cheaper price? The keys lie in keeping customers loyal to brands and products and ensuring a consistently outstanding customer experience.
