National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of the Globe Thermometer.

PB221162

Publication Date	1972
Personal Author	Graves, K. W.
Page Count	64
Abstract	The research project evaluated the globe thermometer in a variety of forms by exposure to extreme environments of simultaneous cooling and heating. It required development of information on the optimum construction and use of the globe thermometer, and on the calculation of radiant heat exchange from globe temperatures. It was demonstrated that design of globe thermometers is not very critical to their performance by fabricating a wide variety of globe thermometers, all of which provided similar temperature readings for a given set of conditions, and yielded predictable temperature readings over a wide range of known conditions of air temperature, air velocity, and radiative intensity. Other conclusions were detailed for the effects upon time lag of several parameters, and various means of reducing time lag in globe thermometers.
