Industry Outlook: Re-Envisioning The MRO Model

Andy Teich Written by Andy Teich, President, Commercial Systems Division, FLIR

Despite high unemployment numbers, our industrial base is dealing with a substantial shortage of skilled technicians. In particular, the skills gap has made it difficult to fill an increasing number of MRO roles, including non-destructive testing.

Many factors are at play, not the least of which is a rolling exodus of well-trained baby boomers heading for retirement. Expect skilled technician shortages in the millions, just in the U.S. Several strategies can address this dilemma.

First: training, training, training. It needs to be a key strategy for companies—one that’s protected and defended, even in adverse times. Training improves productivity, quality and job satisfaction. Continuing education keeps skill levels matched to advancing technology and cuts turnover and downtime. Job training and apprenticeship tax credits for companies offering training will go a long way in sustaining this priority.

Fresh thinking about MRO training will drive real progress on this front. Companies can increase access to training by de-emphasizing four-year degree requirements and increasing the role of tiered training certifications and two-year programs...

Stainless steel reflecting sky temp

This is extracted from a recent message board post:

"I'm curious as to how to adjust for stainless steel reflecting sky temp. The apparent reflected temp of the ground and surroundings is approx 50F. The bottom half of the drum is reflecting this (SP4). The top half is reflecting the sky (SP5). 

In my software, if I set the emissivity to 1, the sky temp in the picture shows -34F.
SP4 and SP5 *should* be the same temp, within a few degrees, based on the operation of the equipment. If I enter 50F as RAT for SP4, I have to enter -95F as RAT for SP5 to get the two temperatures to match.

Why is it -95F and not -34F for SP5? I want to make sure I'm understanding and looking at the image correctly. "

Using Cavities to Solve Emissivity Problems, Here's the Drill

by Bernie Lyon

itc logo (2)Here are two illustrations that I have created to demonstrate how the cavity effect works.

Referring to Figure 1, the “ideal” block has an emissivity of 0.2 and a reflectivity of 0.8  We are assuming that these values are constant and do not change with angle. This is not the case. If thermal radiation strikes a single surface, 20% of the radiation is absorbed and 80% is reflected. (Keep in mind 20% of the radiation – Not the temperature!) If it strikes another surface before exiting, 20% of what remains is absorbed and 80% of that is reflected, and so on.

Therefore, with multiple reflections caused  by cavities, the effective emissivity, or emittance, increases, while the effective reflectivity decreases. This is the reason why holes and cavities appear dark.  They reflect less visible light.

Online Thermography Training Courses

ITC has made the following courses available to IR camera users.
WEB-TH10 Thermography Basics This course is a primer or first course in thermography and serves as an excellent, and recommended, addition to the infrared camera basics operation courses. Thermography involves more than just learning how to use an infrared camera. IR science, heat transfer, thermal tuning, and application knowledge are all essential subjects. 2 ITC Certification Renewal, 2 RCI Continuing Educational Hours (CEHs). This course is FREE.
WEB-TH20 Introduction to Indoor Electrical Surveys using IR Thermography This introductory course is designed to give you a straight forward explanation of how Infrared technology fits in the indoor electrical inspection industry. This course is a replay of a webinar session hosted by an Infrared Training Center instructor and webinar director. This course earns 1 ITC Certification Renewal Credit.
WEB-TH25 Introduction to Outdoor Electrical Surveys using IR Thermography
This introductory course is designed to give you a straight forward explanation of how Infrared technology fits in the outdoor electrical inspection industry. This course is a replay of a webinar session hosted by an Infrared Training Center instructor and webinar director. This course earns 1 ITC Certification Renewal Credit.
WEB-TH30 Introduction to Residential Energy Audits using IR Thermography This introductory course is designed to give you a straight forward explanation of how Infrared technology fits into the residential energy auditing industry. This course earns 1 ITC Certification Renewal Credit. UPDATED February 18, 2011.

Lens Choice for Looking Through IR Windows

by Gary Orlove

More and more organizations are installing IR windows or sight glasses in their electrical equipment so inspections can be made with an infrared camera.

The advantages are obvious: worker safety is improved as thermographers and electricians don't have to open live electrical cabinets, and inspection times can be reduced.

However, what lens choice is the best to use with your infrared camera to provide adequate resolution, and yet see as much of the electrical equipment as possible?

Here are three images that were taken at a power plant looking at an ISO phase buss. The buss is only about a foot away and is taken looking through an infrared window (crystal type).

As you can plainly see, the 90° lens is clearly the way to go.  It provides enough detail for analysis, yet extends your field of view by a huge amount.

Outstanding STS-134 Ascent Imagery Highlights video link

This video makes me proud I was able to contribute to the shuttle thermal imaging program; and makes me sad that it is ending.

It has an outstanding collection of visible and infrared imagery; superbly edited with a great score - just about the best combination of the Science of Imagery Analysis and the Art of “Film” Editing.

New book on IR imaging: the ultimate resource for all users

clip_image002The new up to date book “Infrared thermal imaging – fundamentals, research and applications” by Michael Vollmer and Klaus-Peter Möllmann from the University of Applied Sciences in Brandenburg / Germany gives a straightforward introduction to thermography.

The hard cover book is in full color with about 600 pages and more than 600 images. It may either serve as textbook for beginners or as handbook for expert practitioners such that it may become an ultimate resource for every user of thermography.

Due to the modular structure, readers can start studying whatever they like, be it the theoretical background of cameras, detectors, thermal radiation and heat transfer or be it for example applications for building science, detection of gases and the study of micro systems. A multitude of other applications is also included such as electrical and miscellaneous industrial applications (metal, car, aircraft), medical and veterinary studies, the use in sports and arts as well as surveillance and fascinating investigations in nature.

Cost Avoidance/Energy Savings for IR Thermography

"Has anyone documented Cost Avoidance Or Potential energy savings using Thermography. Ex. Downtime, Labor, Materials. I would be interested in understanding how you determined final cost or energy savings."
This is the $64,000 question, how to justify the cost and benefits of an IR program. The methods used vary depending on your situation, what downtime costs in your facility, overtime and rush ordering to get new parts, lost production cost, your energy cost, etc.
I have selected several white papers that illustrate how different organizations have calculated their costs. Use them as examples of what can be done, and how they are presented.   Right click each image to download the white papers in pdf format.
