Blog #055 – Your THERMOGRAPHY COMFORT LEVEL – Three modes of Heat Transfer. Think on a molecular level.
To be comfortable in using an infrared camera you must be very familiar with the three modes of heat transfer: conduction, convection, and thermal radiation. I’ll use the glossary of the ASNT Nondestructive Testing HANDBOOK, Volume 3 Infrared and Thermal … Continue reading
Thermal imaging cameras can be used to locate unfilled cinder blocks. The principle is thermal capacitance. In the above images I used my Fluke IR Fusion camera at 7am, 10am and 2pm. In the winter the sun rises … Continue reading
So I point my Fluke Ti32 IR camera down on a flat roof at 11pm on a clear night and there’s no wind. I see warm areas and cool areas. The moisture meter verifies the warm areas as moisture. But … Continue reading
There are two very important laws of thermodynamics all thermographers need to understand: the 1st Law and the 2nd Law. And they are not difficult to understand. The 1st Law of Thermodynamics states that energy can be transformed or changed … Continue reading
One of the greatest advancements in infrared cameras came a few years back when FLUKE introduced the IR Fusion cameras. This solved so many issues that had been a challenge for thermographers. It’s easy to see exactly what you are … Continue reading
Review blog #31 and continue with the exercises. As you view the wall with your infrared camera in the blue/red palette you see the following image. Cool wall cavity areas (darker color) and warmer framing (lighter color). Scenario #11 – … Continue reading
If you didn’t get a chance to read the last blog (blog #026) it would be good to go back and take a look at it. It discusses the subject of “emissivity”. Since we learned that “emissivity” is connected with … Continue reading
Every target surface that you point your infrared camera at has a surface characteristic of emissivity. How’s your comfort level with that subject? I talked about this a little in blog #015 (Radiosity! What is it?) As you might remember, … Continue reading
Review Blog #022, #023 & #024 and continue with the exercise. Cool wall cavity areas (darker color) and warmer wood framing (lighter color): Scenario #7 – viewed from the outside during the cooling season (summer) – are the bays insulated? … Continue reading
Review Blog #022 & #023 and continue with the exercise. Warm wall cavity areas (lighter color) and wood framing (darker color): #5 scenario: viewed from the outside during the cooling season (summer) – Are the bays insulated? #6 scenario: … Continue reading
