Committee on Temperature
(The American Society for Testing and Materials) There are several subcommittees
that comprise the Temperature Committee. They specialize in, develop voluntary
standards for, and promote awareness of the standards through various activities
and publications. For instance, Subcommittee, E20.04 on Thermocouple Thermometry,
developed the ASTM Manual on The Use of Thermocouples that is in its fourth edition.
Subcommittees E20.02 (Radiation Thermometery) and E20.05 (Resistance Thermometry)
have similar manuals related to their special sensors under development. Subcommittee
E20.02 also has conducted two small symposia at NIST headquarters, one of which
resulted in an ASTM Special Technical Publication on "Applications of Radiation
Thermomeetry". The Temperature Committee meets twice a year at varying locations
around the USA. Every meeting includes at least one presentation of new measurement
technology and related topics. Consult the website for more details, meetings
schedules and contact information.
Community resource for industrial automation, process control, factory automation,instrumentation
engineers and other technical professionals. Has news, articles, product information,
application and productivity tools, solutions, job postings, product classifieds,
directory of manufacturers and system integrators, career information, technical
discussion forums, and calendar of events.

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!

Courtesy of Belfort Instruments.. Metrological terms including many related to
temperature and moisture measurement
Courtesy Omega Engineering's Tech Reference section-Not everyone will
agree with every term and some seem to be missing (e.g. accuracy, a term most
metrologists do not use and most users misuse is there in place of the more technically
correct 'uncertainty', the term that one will find on a traceable calibration
certificate from a competent source) . However, most of the terms used in instrumentation
and measurement are listed and it is more than a good place to look for a definition
of terms used in temperature sensors and measurement as well as terms used with
other measurement devices!

Celsius Temperature Scale
the most widely used temperature scale in the world and its founder, Anders Celsius
(Note: a very similar scale, the Centigrade Scale, dominated the world until 1968,
when the new scale came about due to a revision in the fundamental reference point
for the AbsoluteTemperature Scale was changed from the freezing point of water
to the triple point of water; a difference of only 0.01 Degrees C. It was enough
of a change to warrant a new name for the temperatures measured more commonly
in science, industry and commerce).

Rudolph, Temperature Consultant
A new web site contains a brief but excellent
summary on just what
emissivity is in terms that the average technical person can understand.
He even gives some very practical advice on how to get a quick estimate of the
emissivity value if you do not have a clue. Please remember, you must measure
carefully and because we have no control over how careful you are or how well
you follow his advice, any errors you encounter are your responsibility not Rudy's
or ours. Things are not always as easy nor as simple as some brief suggestions
