Southampton, PA, USA -- On January 13th the IRINFO Training Conference for 2008 opens in Orlando, Florida. It is aimed at both new and experienced Infrared Thermographers and sponsored by the merry men and women at the Infraspection Institute. It is almost a family affair in many ways! Since I submitted a paper to the conference (and they have graciously accepted it), I am really looking … [Read more...]

Inconvenient Truth or Snowjob?
October 25, 2007 By
Here's the latest I have seen on the debate that won't go away. It's all in video bites and that's no way to do science, but it is a way to get attention, just like PR-wise politicians do. It, too, tells only part of the story, but it appears that our former Vice-President, Al Gore, was either misled in how to read a graph, or was mistaken, or didn't know how to read one or outright lying. … [Read more...]
What’s Great About Optical Pyrometers?
September 9, 2007 By
Not very much, I am sorry to report (Note: Updated 11 November 2009 with latest links and specs from Land Instruments) The replacements for Opticals are very capable devices. Some are just as accurate, if not more so. Plus they are a heck of a lot easier to learn and to use. Even more they have all the newest technologies from detectors to digital outputs. Today Opticals are but a fond … [Read more...]
Why Opticals Are Obsolete..Reflected Thermal Radiation (Chapter 4)
August 13, 2007 By
You would think that a highly accurate temperature measurement device like the Optical Pyrometer would excel at measurements looking into high temperature furnaces, wouldn't you? Lots of people believed that, too not so very many years ago, like in the 1970s. Then the really serious workers, those involved in trying to optimize the trade-off between lifetime of the special alloy metal … [Read more...]
Why Opticals Are Obsolete..Speed of Response (Chapter 3)
July 22, 2007 By
Even More Limitations of Optical Pyrometers (Chapter 3) This problem is one that affects a smaller number of users, but to them it is significant because it limits their ability to use the "power" of Optical Pyrometry to gain precise AND repeatable temperature measurements of their products. The limitation is , of course, the subject of this brief note, speed of response. How quickly does an … [Read more...]
Why Opticals Are Obsolete..Spectral Emissivity(Chapter 2)
July 7, 2007 By
To continue: Chapter 2. Optical Pyrometers were used very much in the development, design and manufacturing of electronic vacuum tubes. Very few are made today, but even in those uses, there were severe limitations to "Opticals". Not the least was the fact that most of the measurements were made on heated components within a vacuum. That meant the user had to correct for the spectral … [Read more...]
Optical Pyrometers are Obsolete Because…(Chapter 1)
June 30, 2007 By
Technology has usurped the capabilities of Optical Pyrometers in almost every measurement situation. First, let me back up and explain about them, how they work and why I think they are obsolete. For decades, the by-word in industrial temperature measurement in many processes was the Optical Pyrometer (aka: DFP, Disappearing Filament Pyrometer, Optical, etc.). A unit well-maintained and … [Read more...]
