TI Temperature Measurement Videos

TI, or Texas Instruments, is one of the world’s most prolific and largest makers of temperature sensors. They make all kinds but their sensors are mostly in the form of Integrated Circuit semiconductors. TI also does an exceptional job in educating users how their devices work and how they can be interfaced and incorporated in measurement systems. Especially useful are the videos showing how some of their other integrated circuit modules can be used with external temperature sensors, like Thermocouples, RTDs and Thermistors. Here’s an example of an interesting one: Contactless Temperature Measurement Made Simple – TMP006 by Texas Instruments … Continue reading

Mercury Thermometers & Alternatives in the USA

Thermometer Image: Courtesy FreeDigitalPhotos.net & mistermong USA — The USA’s National Institute for Standards and Technology (NIST) began an active mercury-reduction campaign in 2007, and stopped calibrating Mercury (Chemical symbol: Hg) thermometers entirely on March 1, 2011. A full range of thermometric calibration services continues for non-mercury devices according to the special NIST webpage at: www.nist.gov/pml/mercury.cfm Mercury is a potent neurotoxin, and every thermometer that contains it is a potential environmental threat. In the 21st century, however, that is a risk that no one needs to take, and a worldwide effort is underway to deploy substitute devices (alternatives) in consumer, … Continue reading

No More Mercury Thermometer Support in USA

New Info Worth Reposting The bulk of this article is from a NIST Press Release with edits that was originally posted on our companion news website, TempSensorNEWS.com on 14 June 2012 as: NIST’s Drive to Replace Mercury Thermometers Gaithersburg MD, USA — NIST researchers have developed a new website explaining the hazards associated with mercury thermometers and discussing potential alternatives for the temperature sensing needs of industry. Reducing the amount of mercury in the environment by recycling mercury thermometers also helps to reduce the amount of electricity we need to produce, which in turn reduces the amount of coal burned. … Continue reading

Mercury-Containing Thermometer Alternatives

This six minute video by the National Institute of Standards and Technology (NIST) describes the types of mercury-containing thermometer alternatives that are currently available for use today in laboratory and industrial applications. This video and the similar ones on the EPA website (www.epa.gov/mercury/nistvideo/index.html) are important adjuncts to the recently announced Calibration Policy change at NIST, NIST will cease offering calibration services for mercury-filled thermometers on March 1, 2011. … Continue reading

Thermometer Articles on Wikipedia

Wikipedia, the free encyclopedia, has some in-depth articles on nearly everything. The ones on liquid in glass (LIG) thermometers are very detailed but subject to some variable technical depth, as is the mode of Wikipedia. Despite that possibility, these are, we think, some excellent resources on thermometers. “Thermometer” at http://en.wikipedia.org/wiki/Thermometer, includes materials organized the following way: Contents 1 Primary and secondary thermometers 2 Temperature 3 Early history 4 Calibration 5 Precision, accuracy, and reproducibility 6 Uses 6.1 Other types of thermometers 7 See also 8 References 9 Further reading 10 External links “Medical Thermometer” at: http://en.wikipedia.org/wiki/Clinical_thermometer includes information organized as … Continue reading

The Thermometer—From The Feeling To The Instrument

An article by Jaime Wisniak Department of Chemical Engineering, Ben-Gurion University of the Negev, Beer-Sheva, Israel, wisniak@bgumail.bgu.ac.il Abstract: The thermometer, as we know it today, is the result of a long trial and error process. It began with a physiological description of temperature and evolved to the present state. The different stages in its development reflect the state of science at the time as well as the ingenuity of scientists to realize and overcome the shortcomings of science during each stage. Published in: The Chemical Educator, Vol. 5, No. 2, S1430-4171(00)02371-X, 10.1007/s00897990371a, © 2000 Springer-Verlag New York, Inc. Online at: … Continue reading

Temperature (T)-Bob Abel on YouTube

Dr. Bob Abel of Olympic College in Bremerton, Washington (USA) has a series of YouTube videos that we think are very well done. His low-key and sometimes humorous approach to the basics of science and temperature, as concepts, and how some temperature sensors work, are some of the cleverest and most viewer-friendly ones we’ve seen to date. Below are his two brief presentations on temperature and scale/unit conversions in lumps of about 5 to 7 minutes each. There are many more at www.youtube.com/olympiccollege. First: … Continue reading
