The topics covered are:

  • What is temperature?
  • International temperature scales
  • Temperature Units
  • Conversions between temperature units
  • Beamex temperature calibration products

Beamex’s business is calibration.

Since technology continues to rapidly progress, companies need to be more efficient with less resources. At the same time, new regulations put constant pressure on manufacturing operations to maintain a high level of plant safety and product quality. With these in mind, we are here to help our customers to find a better way.

Global Temperatures | Global Warming, is it Real?

Recent International News about Global Warming and a few link errors in our original webpage with this same title, prompted a recast of this page in the new format of this website and fix and amplify it.

It seems that only those with the least knowledge of the Climate Change situation seem to be arguing about the basic fact of Global Warming. It is real and to deny it, is, in our opinion, an indication that those who do so, should take the time to learn the real facts, and if necessary the science underlying them.To those who don’t trust science, better get rid of your TV, Internet, smartphone and all that other “stuff” based on real science; they are then, also, not tobe trusted.

Denials don’t change facts:

  • Glaciers are melting worldwide, so is sea ice.
  • The average temperature of the Earth has been increasing for many years,
  • Sea levels have been and continue rising.
  • Carbon Dioxide content in the atmosphere is increasing.

Real Climate BannerCountries meeting at U.N. environmental conference in Montreal Canada on November 20, 2005 adopted the rules for limiting emissions of greenhouse gases under the U.N.’s Kyoto Protocol.

Of course this is connected to the concerns over Global Warming, with Carbon Dioxide emissions from fossil fuel combustion long considered a major source contributing to the problem.

There has been some speculation in the media along with some outright condemnation of the concept of Global Warming. Yet, scientists and other media, mostly quoting science reports, indicate that Global Warming is indeed upon us.

The book The Discovery of Global Warming tells much of the history behind the concern. It would seem that it is about time we got up off our collective rear end and made some changes.

What is the truth? Is there a clear answer to the question about Global Warming’s reality? Is the science reliable?

Are the temperature measurements and trends of ancient temperature measurements to be believed?

What about the questions raised by many politicians and in books by more noted writers, like Michael Crichton in his best seller State of Fear?

Today the answer seems much clearer. It is a real concern.

We need to get our leaders to acknowledge the problem and take some positive steps to work with the rest of the industrial nations to abate it!

There is obviously much more.

First, realize that the Union of Concerned Scientists (UCS) published a detailed rebuttal to Crichton’s comments in his book. Their very interesting website also has a complete story on Global Warming, as one might expect from concerned scientists.

They are detail-oriented, not like most of the critics of global warming, many of whom appear to seek simple answers! No is the answer of those who refuse to face facts.

Then there is RealClimate.org, a website founded and maintained by scientists to tell the story details about Global Warming, Climate Change and its likely consequences. It is a notable effort to help the rest of us understand the real debate – among scientists, not politicians, religious zealots or modern Luddites.

We found their website so compelling that we have added their current newsfeed at the top right of this page.

The American Institute of Physics has a summary page, part of a series of pages on the subject.They are authored by the same scientist and science historian, Dr. Spenser R. Weart who wrote the book on Global Warming described and pictured at the top of this page.The pages brings you up to date from the 2003 book through February 2014, with keylinks to other websites where the details can be found.The amount of evidence is staggering!

For those so inclined to do their own analyses, there are tons of data available from monitoring websites around the world.

One of the favorite data sources is the Hadley Meteorology Centre, a British Government facility, in the UK. Their webpage shows the impacts global annual increase of just a small amount.

They also publish the actual data in tabular format that can be easily imported into almost any spreadsheet like MS Excel, Pages, Lotus 1-2-3, Open Office or Star Office Calc, then plotted and analyzed separately from ones generated by the Hadley folks.

Is the data from which the averages are calculated valid? There’s little doubt mostly because there has been such widespread interest in the subject and it has been the attention of so many capable people.

Are the answer and the calculations simple? In a word, NO!

They are complex and require attention to all sorts of details including all the other influencing factors involved in cyclic and irregular changes in the Earth’s temperature and its distribution.

The recent, popular book, A Matter of Degrees by Prof. Gino Segre at the University of Pennsylvania talks about aspects of Earth’s temperature history and the many astronomical and other physical factors that influence it.

The Union of Concerned Scientists (UCS) and the World Resources Institute jointly operate a website called GLOBAL WARMING: Early Warning Signs at www.climatehotmap.org.

They present a world map marked with tags to indicate “Fingerprints” and “Harbingers” of Global Warming as further education to the fact that Global Warming is not just happening in the future, it has already begun and the evidence is there, if we care to take notice.

Wikipedia, The Open and Free Encyclopedia on the Web has an extensive array of articles and links about Global Warming. As of December 2, 2005, the following statement, with embedded links to sources, appeared in the article:

“The scientific consensus on global warming is that the Earth is warming, and that humanity’s greenhouse gas emissions are making a significant contribution. This consensus is summarized by the findings of the Intergovernmental Panel on Climate Change (IPCC).

In the Third Assessment Report, the IPCC concluded that “most of the warming observed over the last 50 years is attributable to human activities”. This position was recently supported by an international group of science academies from the G8 countries and Brazil, China and India”. <

There are many more websites with wide ranging information about this and related ecological conditions. One of the best that we have found is ClimateArk the Climate Change Portal. It has an RSS news feed that is updated daily and a search engine that searches the entire contents of 2000 reviewed climate websites.

The Significance of Thermowells

Consider relevant factors and standards

Thermowell Drawing

Online — In a May/June 2013 article in InTech Magazine Basics of thermowell design and selection”, author Ehren Kiker describes why thermowells are important and how their key parameters can be determined for a particular use situation.

The article begins:

“When planning for a temperature measurement application, a fair amount of consideration is typically given to sensor selection (e.g., thermocouple vs. RTD) and wiring of the output (e.g., transmitter vs. direct wiring), and how these factors will affect the measurement. Often, by comparison, relatively little consideration is given to the mechanical components of the sensor assembly, particularly the thermowell.

“Of all the components in a typical temperature assembly, a thermowell would seem to be the simplest and least critical. In reality, the thermowell is fundamentally important because it directly and significantly affects the life span of the sensor and accuracy of the measurement. It also protects the closed process, providing plant and personnel safety.”
