The triple point of argon (83.8058 K ) is one of the most commonly used fixed points for the calibration of standard platinum resistance thermometers (SPRTs) at temperatures below 273.16 K. It’s a defining fixed point of the International Temperature Scale of 1990 (ITS-90). Fluke Calibration recently designed a new Triple Point of argon system with the goal in mind of achieving both efficiency and accuracy in calibrating SPRTs.

There are a few instruments used to perform infrared (IR) thermometer and IR imager calibration. These instruments fall into two categories, cavities and flat-plates. To calculate the uncertainty in using these instruments, the temperature uniformity must be known. This is especially true with flat-plates. This uncertainty may be given in an instrument’s specification. However, there is not a standardized test method to test the uniformity of a flat-plate calibrator as there is with other classes...

Curb explosive potential with intrinsically safe tools. For those who work in industries where flammable materials are present—such as petrochemical and pharmaceutical plants, oil platforms, refineries, pipelines, and mining—the potential for an explosion is a daily reality. All it takes is a flammable material coming into contact with air and an ignition source.

Cogeneration - also known as combined heat and power or CHP - is the process of generating electricity and usable heat at the same time. The term has a modern, "green energy" ring to it, but cogeneration has been around since Edison's Pearl Street Station used heat from its turbines to warm the buildings of lower Manhattan in the 1880s.

With energy savings, there's intent and then there's plan. Industrial facilities in the United States show a sustained interest in energy management. That's the intent: Reduce overall energy usage or sustain usage but increase the amount produced per kW used.In manufacturing, a plan will only stick if it has both the wisdom of experience guiding the vision and the ROI numbers to back up the effort. But in energy, there just isn't the body of research out there for an industrial plant manager to use to set baselines for what "reasonable" energy usage looks like in a manufacturing facility.

You may have read about the new Smart Grid currently in development by various manufacturers, utilities and government agencies worldwide. At the highest level, the idea behind the Smart Grid is to add far more "intelligent" devices to the transmission of high voltage across a large power grid such as the continental U.S.

Now that budgets and staff are smaller, it's not uncommon for management to ask for justification before authorizing tool purchases. The key phrase here is return on investment (ROI), or how long will it take to save enough money, using the tool, to cover the cost of purchasing the tool.

Kiln-drying wood is a 24/7 process. That is why Zena Forest Products mill owner Ben Deumling was so anxious to ensure that the new dry kiln he was setting up was as energy-efficient as possible. Deumling started with a 24-foot kiln built from a repurposed refrigerated shipping container, and installed a set of three ¼-horsepower single-phase fans to move the warm air over the wood.
