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:  http://www.ces.ncsu.edu/nreos/wood/wpn/methods_moisture.htm 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

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.

Or, http://www.epluse.com/fileadmin/Humidity_calculator/EEHumidityCalculator.swf 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

Precision & Accuracy in Measuring Surface Temperatures

A subject rife with errors, no matter how you look at it. There’s a classic pair of books on temperature measurement that are hopelessly out of print. We are fortunate to have both in our little library. They are: 1. “Temperature Measurement in Engineering“, Volume I, by H.D Baker, E.A. Ryder and N.H. Ryder, John Wiley & Sons, Inc. New York and Chapman & Hall, Limited, London (Copyright 1953) Library of Congress Catalog Card Number 53-11565, and 2. “Temperature Measurement in Engineering“, Volume II, by H.D Baker, E.A. Ryder and N.H. Ryder, John Wiley & Sons, Inc. New York and … Continue reading

The EarthTemp Network

  Online — EarthTemp is a network to stimulate new international collaboration in measuring and understanding the surface temperatures of Earth. This will involve experts specialising in different types of measurement of surface temperature, who do not usually meet. Their motivation is the need for better understanding of in situ measurements and satellite observations to quantify surface temperature as it changes from day to day, month to month. Knowing about surface temperature variations matters because these affect ecosystems and human life, and the interactions of the surface and the atmosphere. (for more details, see motivations and objectives and scientific context … Continue reading

Why Noncontact Sensors are So Named

And their really big advantages At the risk of being insensitive by saying this sounds like a ‘Duh” moment let’s not. Let’s explore just what it means and why it is significant, especially in the case of temperature sensors. The fact is, noncontact temperatures sensors, and similar noncontact sensors for size and shape are so-called because they measure a certain property by not contacting the object itself. Aside from the obvious side benefits of not causing any changes to the object being measured, noncontact temperature sensors have some significant benefits and accompanying advantages over contact temperature sensors. As an aside, … Continue reading
