What to do when tasked with inspecting thermally reflective surfaces?

Paint it Black?

No, this blog isn’t about The Rolling Stones – it’s about the practice of enhancing emissivity in the field. When a thermographer is tasked with inspecting thermally reflective surfaces there are two options.  Either accept that the surface doesn’t emit well—and therefore reflects very well—and therefore can’t provide reliable qualitative or quantitative data, […]

Vision Tests and Thermography

The onset of presbyopia can have an impact on your ability to perform high quality thermographic […]

What Kind of Hot is It?

The discovery that accurate temperature measurements are many times difficult in electrical applications of thermography can be a hard pill to swallow.  Electrical apparatus are often made from metal that’s bare, so emissivity is low, and thus temperature measurements are unreliable.

The good news is that despite this fact, electrical anomalies can be relatively easy to […]

Transformer Cooling Tubes

One of the easiest, and often safest, types of electrical apparatus to inspect are oil-filled transformer cooling […]

Focus First

If you’ve had Level I Thermographic Applications training course you most likely heard the mantra of “Focus First!” from your instructor, and with good reason! Of all of the camera settings that can be adjusted by the camera operator, focus is by far the most important.  Focus is essential to both image quality and temperature […]

Infrared Cameras: The Answer my Friend is NOT Blowing in the Wind

Regardless if you’re inspecting buildings, roofs, or electrical or mechanical apparatus, when you have an abundance of air movement across a surface, there is an increase in heat loss or gain on that surface from convective cooling or heating.

Convective cooling is often discussed in many applications of thermography.  Often the result is cooling of anomalous […]

Exposing Electrical Panels

Whether it’s high rise office buildings, hospitals, or an industrial facility, the approaches to accomplishing an infrared electrical scan vary as much as the locations.  One universal thread throughout these inspections is the manner in which most electrical maintenance folks expose panels for inspection.

 

Most industrial grade panels have a two part cover but these configurations […]

Mechanical IR Safety

There’s a lot written about electrical safety as it applies to infrared inspections.  The danger of electric shock and exposure to arc flash hazards must be considered when inspecting electrical apparatus with thermography. What isn’t discussed nearly as often are the hazards associated with mechanical infrared inspections, of which there are many.

How do You Get to Carnegie Hall?

The punch line to the old joke, “How do you get to Carnegie Hall?” is three simple words, “Practice, practice, practice.”  The same would hold true if there was a thermographic equivalent to Carnegie Hall. You’d get there with practice … lots of it!

Some folks who come to Level I infrared training, however, express that […]

A Thermal Success Story

We have several customers that we visit and perform infrared scans for on a regular basis. Recently we were in a textile mill in a state where we’ve been performing inspecting for the past four years.  The equipment list has remained virtually unchanged in the time we’ve been inspecting there. The only variances were during shutdowns for […]
