Strained strain relief?
During a recent survey I was looking at some overhead feeders going into a building. I noticed a "hot spot" on one of the four strain relief cables supporting the feeders. The one on the left which is in full sun is showing a lower temperature than the far right one, which is in partial shade. The grounding jumper going between the cables is not showing any of this temperature rise so I ruled it out. So my question is, could the strain on the cable be causing it to show the higher temperature?
Bolt/nut on motor housing
Came across a motor with hot bolt/nuts on the motor housing. This was not a trend with other motor in the same room. Any thoughts?
Theses bolts run the entire length of the motor. I know this to be a heat transfer from internal, but not familiar with coming across this scenario. Bolts on shaft side were much warmer.
Thermal image viewing
I have a good many images to look through and was curious if there is any fast way to bring up an image and check various spots on it? The measurement tools are there once I get it into reporter but before I get to that stage I like to look through them outside of the report form. Viewing like a normal image in Windows XP can only let me see so much. If I could pull an image up close to that quick but have some measurement tools would be a big help.
So is there anything that will do what I’m wanting? The web viewer always seems slow to me so I’d rather use something else.
And of course if YOU have a question or want to start a discussion on a topic, we would love to hear from you. Just start a new thread on a message board.

Last Month's Brainteaser
We had 26 responses, but nobody had the correct answer. Congratulations to our thermogram contributor, Axel Dougan for stumping everyone!
Here is the correct explanation:
“I wondered why the 3 windows on the right of the picture reflect the cold sky on the upper part, but not on the lower. Taking it at night I did not notice any difference in the visible light coming out. The answer (obvious in hindsight) is that the insect screens are in place on the lower portion.”

Moisture in Airplanes
By Ralf Grispen
Thermal imaging helps to detect water ingress in airplanes. Composite materials for modern aircraft need to be extremely sturdy and lightweight. These materials are vital to aircraft performance and airworthiness. A structure used in many parts of modern airplanes is the honeycomb. This structure has an appearance much as the honeycomb found in a beehive and is extremely light and strong. As long as they are intact, honeycomb structures offer exceptional weight to strength ratios but it is important that the structure is bonded to the outer skins, of e.g. airplane wings, in a reliable way.
Even with the best bonding process, the bond between the honeycomb material and the sheet material is not perfect. This presents a potentially dangerous problem; water ingress in the honeycomb structure!
With an infrared camera it is possible to search for water ingress in these composite parts of aircrafts.
This video shows the procedure and a live inspection of a Boeing 767 cargo airplane from Star Air Denmark. Many thanks to these guys from Star Air and of course our infrared camera supplier FLIR Systems.
Straight from the World Wide Web, here is what's going on in the world of infrared thermography.
