About 25 years ago, I first visited the Instrumentation Labs at Oak Ridge National Laboratories (ONRL) at the invitation of the late Bob Shepard. Bob was a pioneer in many areas of temperature measurement and at that time was the Chairman of ASTM Committee E20 on Temperature. He was also head of the lab at ORNL.
He introduced me to Johnson Noise Temperature (JNT) measurement and showed me a prototype device that they had developed at Oak Ridge to implement the method as an possible alternate means to verify the calibration in situ of thermocouples in a nuclear reactor environment.
While the method was very complex, Bob was convinced it would eventually become commercially viable, if for no other reason than it was a fundamental technology related to the Absolute Thermodynamic Temperature Scale (Kelvin Scale) and required no calibration.
Work has continued to this day at ORNL and elsewhere. More recently, the staff at the National Institute of Standards & Technology (NIST) Thermometry Group have been producing some remarkable results, prototype devices and a raft of technical papers on the subject.
First a description about this unique temperature measurement method that has been studied for more than 30 years. Read the rest of this entry »
Just spent four days at the several Infrared Conferences that are part of the SPIE DSS meetings plus one of the world’s biggest Infrared & Optical Expos in the world. It was all held in Orlando Florida, USA at the giant Marriott World Center.
ThemoSense was kicked off by the Fourth Annual Vendors Presentations & Reception on Monday evening and was followed by 13 Technology applications sessions ranging from Pyrometry to Image Fusion and NDE Materials Evaluation during Tuesday, Wednesday & Thursday. Read the rest of this entry »
Reference:Best Practices from The Snell Group, January 31, 2008“Remember, it is important for thermographers to take an annual vision exam. At a minimum it should include a Jaeger Eye Test, to see if you can read small print, as well as a color-blind test such as the widely accepted Ishihara Color Deficiency.
“If you are a male, especially, you may have some type of color deficiency. Having a color vision deficiency does not mean you must give up thermography.
“What it does is help you better understand what color palette to use and where you need to be careful when interpreting color thermograms.”

The project was funded primarily by DOE, with other support provided by utilities and manufacturers. It involved two separate studies to test demand-response concepts and technologies.
The Olympic Peninsula Project found homeowners are willing to adjust their individual energy use based on price signals — provided via information technology tools.
The Grid Friendly™ Appliance Project demonstrated that everyday household appliances can automatically reduce energy consumption at critical moments when they are fitted with controllers that sense stress on the grid.
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 forward to this meeting.
The Conference will be also chock full of people from NORMi, the Mold Inspection people for the first time, plus a number of regular attendees from both the USA and Overseas.
There will be a lot of new tips and thermography lore to learn and report on both here and on TempSensorNEWS.
I have been a regular attendee for the last five or six years and am pleasantly surprised by the new things presented each year. Jim & Chris Seffrin sure have their fingers on the pulse of the industry!
Attendees get to see some of the latest items available from the IR Thermography suppliers at the adjoining Expo. I plan to place regular reports from the Meeting and Exhibition and, if it works as advertised, actually submit a few videos feeds on new products featured and some of the events at the meeting. (I am bringing my new camera, just in case.)
So tune in, or keep an eye on our RSS news feed next week - (NOTE: now available through FeedBurner, Google and Yahoo) .
Surging demand for high quality temperature sensors leads to increased pre-sales engineering
Framingham MA — November 19, 2007– Nanmac Corporation, supplier of thermocouples to industry since 1956, has hired Anand Pandey as Director of Sales Engineering, effective November 1.
Mr. Pandey holds a B.S. in Engineering from Boston University and an M.S. in Mechanical Engineering from Northeastern University, and is returning to NANMAC after a two year hiatus.
Mr. Pandey is also a certificed project management professional (PMP) from Villanova University. His charter will be to manage and provide engineering support, and increase U.S. sales in top segments such as Aerospace, Electronics, Heat Treating and Plastics.
NANMAC recently hired a new marketing director, and has expanded their sales, engineering and support center for Asia Pacific in Shanghai China.
NANMAC’s recent growth is partly attributed to their expertise in custom engineered thermocouples, which allow manufacturers to precisely control their R&D and Production facilities, saving raw materials and energy, and ensuring less downtime.
Additionally, Nanmac has completed testing, and has now fully launched Live Chat on their website to provide faster solutions for clients and partners around the world. This and other recent enhancements in support complement the expansion of manufacturing and engineering capabilities in Framingham Masshachusetts.
About Nanmac
Nanmac Corporation designs and manufactures temperature sensors and related products and services to automotive, aerospace, defense, medical, plastics, energy and electronics companies in the U.S. and thirty other countries. Learn more at www.nanmac.com
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.
I tend to believe the former and not the latter, after all, he did invent the Internet, didn’t he, or did he or his competition claim that he did…hmmmm?
Anyhow, if you have the stomach to see yet another statement about Global Warming or Global Warming hoaxes, this one has a few interesting bites next to each other!!
