    Happy Thermographer Feet

    • 0 Comments
    Happy Feet. What a cute movie with singing and tap dancing penguins (my little niece loves the movie). However, I’m not going to be talking about penguins in this blog. Instead, I’m talking about the feet at the end of our legs and keeping...

    What the “Bleep” caused that?

    • 4 Comments
    Few things are more exciting for me than finding a thermal anomaly I have never seen before or one I cannot quickly figure out its cause. Well, there may be a couple other things I find exciting, but those are for a different blog! I have been involved...

    A Look Back at Infrared - What I Wish I had Learned Earlier

    • 0 Comments
    Someone recently asked me, after my 15 years in this technology, what would I have liked to know in the beginning? Infrared was in a sense a novelty in the beginning, a way to do something other bending conduit and pulling wire. I would have liked...

    The Power of Infrared

    • 0 Comments
    I have been an on-site thermographer and currently work as traveling service thermographer. These working methods at first seem to be very different, and in many ways they are. There are also quite a few similar concepts with both. One of the similarities...

    Electrical Switching Devices: Making Thermal Sense

    • 0 Comments
    Switches are pretty widely utilized in electrical applications. They can go by any number of names, depending on the particular application. In utility applications we hear terms like “air breaker” or “cutouts,” and in industrial...

    Infrared Report Preparation

    • 3 Comments
    Infrared reports, what should be in them and what should not? If there was a one size fits all answer, life would certainly be easier! But, each type of inspection requires different information to be presented to the customer. To make things easier,...

    Calibration Intervals: How Often?

    • 2 Comments
    Like any other measuring instrument, infrared imagers require periodic calibration. One of the most often asked questions about imager calibration is how often to have it performed. The answer you get will largely depend on who you ask. Ask the representative...

    Physical Challenges and the Thermographer

    • 0 Comments
    As a thermographer, your physical condition can become apparent when performing inspections, especially at older and larger plants. For example, climbing some grain handling facilities have proven to be a good workout to get me ready for Elk hunting season...

    Electrical Inspections; Don’t Camp Out

    • 0 Comments
    I’m talking about how much time is spent in front of open live electrical systems, in what is commonly referred to as the “Danger Zone.” I have seen quite a few beginning thermagraphers spend entirely too much time trying to get the...

    Can “Cold” Indicate an Electrical Fault?

    • 0 Comments
    Often times as thermographers we have it drilled into our head to look for “hot” spots. In our search for these hot spots, however, is it possible that we’ve been overlooking potentially important “cold” spots? Let us...

    Blowin’ in the Wind: Convective Cooling Indoors

    • 0 Comments
    When the discussion of convective cooling comes up, people always discuss the issues they have outdoors. Substation inspections, building envelope studies in windy locations, those sorts of things. I always like to break out a tale I have about an anomaly...

    What Does it Take to Start an Infrared Program?

    • 0 Comments
    I have been asked so many times, “What does it take to startup an IR program?”Surprisingly, I never have the same answer. Not because I am inconsistent, but rather that there is no one correct answer. Each site, plant, or organization is going...

    New Thermal Imager Features; Necessary or Not?

    • 0 Comments
    What features are useful on a camera and which are just “fluff”? This is a question you will likely broach if you’re in the market to purchase an infrared camera. In my 13 years working in this field, I have seen everything from “bare...

    Low-Speed Rotating Equipment: IR to the Rescue!

    • 0 Comments
    I usually don’t like to generalize, especially when it comes to people, but I have to say that maintenance and reliability folks are pretty much the same no matter where I go. From the West Coast to New England, the upper Midwest to the Deep South...
