EDITORIAL

Welcome to the February 2002 edition of TemperatureSensorNews. The big news this month is the addition to our Web site of an expanded applications section. The theme is applications of temperature-measuring thermal imagers, otherwise known as Thermography. This section consists of a Index with an explanation of the basic uses of these, the world's most expensive temperature sensors. It is followed with a guide to some of the major sources of thermography applications Web sites on the Internet; places where dozens of full color thermal images, even color videos, can be found. There's a page just on available resources such as professional organizations and technical meetings that support this industry. (If you think that last month's review of the "Thermal Solutions" topical meeting had an influence on this month's site expansion, you are correct; the concept grew like a weed.)

Since Thermography is practiced by both large and small companies with many small companies providing third party services as independent organizations, there is the beginning of an index/directory of thermography service companies. Keeping to our Web site's philospophy of not reinvernting the wheel, most of these listing are links to ones that are on other sites; we're merely providing a context and guide to the important ones that we have reviewed. Also included are a few individual service provider sites that stand out as exceptional, in our opinion. Finally, we have significantly updated and expanded our page on the companies that provide thermal imaging equipment and put on a seperate, new page the organizations that provide training for thermographers.

Not to waste a theme, the product of the month is a Thermal Imaging Camera, The PalmIR made by Raytheon, but sold also, under a different name, PPM+, by Land Infrared. The key features are very much the same, but we suspect that Land has done some special magic to the accuracy specifications for measurement made with their version. (If only there were some independent labs reporting on instrument performance, or some common standard for reporting performance data.)

The planned site update on thermowells is still in progress with much data colected and sites visited. However, the Thermography project tok over this month. We expect thermowells to be ready for March's update.

There is no book or meeting review this month. We had not received any new books until very late in February. A new book has arrived and is in process. We'll let you know next month.

Don't forget, at the end of March, actually on April 1st, the SPIE Thermosense meeting begins in Orlando. We will be attending and expect to report on the meeting for the April issue.

See you next month!

NEW Links of Interest & NEW Vendor Listings - February 2002

New Pages

Four new pages on Thermography:

Thermography Index, A brief introduction to Thermal Imaging and Thermography with an index to the pages on the web site related to the various aspects of the subject.

Thermography Resource Some of the organizations, societies and topical meetings that provide resources for this technology

Thermography Service Providers, A directory of directories and specific service providers that stand out with informative web sites, in our opinion.,

Thermography Training Companies a list of links to the training groups that support both the individual thermographer and the larger organizations who need ongoing training resources to support their thermography orerations.

Page Updates/Links of Interest added

Applications Pages

Thermal Imaging Applications- Greatly expanded.

Data Acquisition Page

ACCES I/O Products
Analog to Digital with Signal Conditioning for RTD's, Thermocouples, 4-20mA signals, Voltage inputs, to Digital to Analog cards, to Serial Communications such as RS-485 and RS-422 including Optical Isolation.Plug in products in ISA, PCI, RS-485 Bus for REMOTE I/O, and PC/104.

Links Page

(The) Silent PC or Noiseless, Intelligent PCs
Noise from PCs have been taken as a fact of life by most, but Tomas Risberg in Sweden knows that the sources are those fans and drives that make excessive noise. Most do, he shows, because there is a close relation between heat dissipation, temperature and PC acoustic noise emissions that can be easily overcome by better engineering and cooling methods. A most detailed, well documented and interesting web site! What's more he shows how application of temperature sensors can help!

Thermocouples and Links Pages

Pentronic is the leading supplier of temperature measurement equipment in Scandinavia for for industry, research and education. Manufactures temperature sensors, primarily Pt 100 and thermocouple elements. Their calibration laboratory is accredited for temperature, electrical resistance and current (SWEDAC 0076). The laboratory is unique among European manufacturers and has resources to rival many national laboratories. They also offer an extensive range of calibration training programs. Visit their website to get an idea of what can be done with technical information on the Web.
