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


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

Measuring Moisture in Wood

Methods of Moisture Content Measurement in the Lumber and Furniture Industries* by: Phil Mitchell, Assistant Professor and Wood Products Extension Specialist, North Carolina State University Source: The moisture content of wood is a basic property that can impact subsequent machining, gluing, finishing, and product performance. It is the job of wood product producers to establish a moisture content in the wood that will be similar to what the wood will experience in service. To accomplish that, manufacturers must develop a standard procedure that will measure wood moisture content consistently and accurately. This brief note discusses methods of moisture content … 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

Multilingual Humidity Calculator Online

From E+E Elektronik The humidity calculator from E+E Elektronik is used for the rapid conversion of humidity measurements. Uniquely, the humidity calculator also includes measurement uncertainties in the calculation. The humidity calculator can be used online using your favorite Web browser. Thus, it does  not require any program to be installed on a PC. Or, An Explanation of humidity calculator measurements is found here. But it is more than a simple help page it is, as entitled on the E+E Electronik website “Explanation of humidity calculator measurements”, with a definition or description of each term and the appropriate measurement … Continue reading

Multiple Sensor Type Vendors

There are numerous distributors who sell many temperature sensor products and accessories, among other things. Some manufacturers specialize in producing a significant number (usually three or more) of different types of temperature sensors and sell to either a distributor network or directly to the public by Internet and/or Catalog sales (telephone or mail). Start your search either here for vendors of multiple types or, if you are seeking a specific type, go to the vendor page index or directly to a page describing sensor types; you can find the vendors of specific types from many different places there. When all … Continue reading

Thermocouple Junctions Are Not Voltage Sources!

by R. P. Reed, Ph.D, PEret NOTE: The following is a brief overview of a special article written and published here by a noted authority on thermocouples. Dr. Ray P. Reed. Dr. Reed is a retired researcher from Sandia Laboratories in New Mexico, USA. He is a semi-retired, yet still a contributing member of the ASTM International Committee E20 on Temperature Measurement. He has written and presented many professional and peer-reviewed articles on temperature sensors, notably thermocouples in his long career. His list of publications is on another page on this website, This new article from R.P. Reed is published … Continue reading

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
