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 … Continue reading

IMPROVING HUMIDITY MEASUREMENTS IN METEOROLOGY

A product with a unique advantage Air humidity and temperature play an important role in meteorology. Highly accurate measurements of these climate parameters form the basis of accurate forecasts and meaningful records. The E+E Elektronik Model EE33 series humidity and temperature sensor is the only one on the market with a double-heated probe. Both the sensor tube and the sensor element are heated. An application note, free for download from their website, tells the rest of the story. You can download it be clicking here. If that does not work, as sometimes happens when organizations “refine” their websites, we have … Continue reading

The Significance of Thermowells

Consider relevant factors and standards 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 … Continue reading

Wake Frequency Calculator by TempSens Instrument

Plus two additional Calculators An online resource calculator for estimating the Wake Frequency of a thermowell in a flowing stream. According to the website: “TEMPSENS WAKE FREQUENCY CALCULATOR is easy to use and it also ensures that thermowell is designed within the dimensional limits of PTC19.3, 2010. This calculator establishes the practical design considerations for Thermowell installations in power and process piping, which also incorporates the latest theory in the areas of natural frequency, Strouhal frequency, in-line resonance and stress evaluation.” The same webpage provides a Temperature Calculator to convert the Emf (mV)/Ohms generated by thermocouple & RTD to the … Continue reading

Temperature Sensor Organizations in The Open Directory

About the Open Directory Project The Open Directory Project (http://www. dmoz.org) is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors. It is also the Web locale where most of the large Internet Search Engines and Directories look for new entries or websites to scan for new information. About Temperature Sensor Organization Listings on the Open Directory Temperature sensor suppliers and related organizations are mostly found on two separate pages within the Open Directory, Listing for Science: Instruments and Supplies: Laboratory Equipment: Temperature Sensors and Thermocouples and … Continue reading

About ITS9

(Borrowed text from the official website of The Ninth International Temperature Symposium – ITS9.org) (ED NOTE: The Call for Papers is still open!) Gaithersburg MD, USA — Approximately once every 10 years since 1919, the International Temperature Symposia have provided a forum for the presentation and publication of work related to the measurement and control of temperature, with topics ranging from fundamental research on temperature scales to practical measurement or control solutions in a variety of fields. The 9th International Temperature Symposium (ITS9), together with a technology exhibition, will be held in March of 2012, in conjunction with the Measurement … Continue reading
