Last week I talked about the value of following professional standards. Not only do they lay out the best “recipe” for success but standards are also widely accepted as “collateral” in most industries where we work. By following standards, your work will immediately gain credibility. Section 14 of ASTM C-1153, Standard Practice for Location of [...] The image palettes we have available to us are remarkable. They’ve come so far since I first got into this business in 1983. We can now also easily change the palette in the software. Wow! The Fluke AMBER palette with red and blue saturation indicators is a nearly perfect palette to use, especially in the [...] Don’t get stuck in 2D. Watch this informative video on how 3D reporting in Fluke SmartView software can give you a view from EVERY angle. When viewing traditional 2D images sometimes situations can be misdiagnosed. See what a difference 3D reporting makes. To see a video demonstration of Fluke SmartView, click HERE. And remember, Fluke SmartView [...] Buildings and equipment do not maintain themselves. When it comes to preventive maintenance, you have to proactively seek out problems before they occur to prevent unplanned downtime. Thermography can be an invaluable tool to prolong equipment life, save money and increase the safety of your workforce. If it’s your job to keep everything running smoothly [...] The work we do as thermographers has immense value; I don’t mean to imply that the world would stop turning without us, but thermographers do a great deal to have it turn more smoothly and efficiently! The disastrous situation in Japan reminds us of how vulnerable the complex systems and machines we have grown to [...] Last week we talked about dressing for winter weather, in a ‘how-to’ post on reducing heat loss from our bodies. We’ve all experienced how difficult it is to stay warm when that “Old North Wind” is blowing cold. Wind—or forced convective heat transfer as it can also be termed—seems to “go right through” even the [...] John Snell in Winter Mode As winter makes itself known—undeniably so here in Vermont, with hard frosts, flurries of “hard water” and a couple feet of snow in the mountains—it is useful to review the procedures and techniques for using our imagers to find problems, especially those in buildings. Industry standards, including the new RESNET Guideline, [...] Over the past several weeks, we’ve seen how essential it is to make corrections to the raw data our imaging systems detect. Without these adjustments to emissivity and reflected background temperature, we can never achieve the ±2ºC accuracy that our systems are capable of achieving in ideal circumstances. One additional correction—for the partial transmission of radiation [...] In life we often make corrections to our first impressions or first courses of action. Whether we are following directions while driving, stepping on the scale to check our weight or adding cream and sugar to our coffee, corrections are an important part of getting it right! Without them, we don’t get to where we [...] Over the past several weeks we’ve talked about how heat “moves,” or what is called heat transfer (steady state and transient) and the modes of transfer (conduction, convection and radiation). While it is important to have a solid understanding of the theoretical basics, how does all this really apply to what we do every day [...] |
