Abstract:

A study was made of electrical methods of measurement of force in the range below one pound. The study was directed toward assessing the present state of the art and providing guides toward new or improved techniques applicable to advanced military flight vehicles, particularly in regard to environmental extremes. The nbounde strain gage has considerable merit for t e direct measurement of force over a m derately wide range of environmental conditions. Where only dynamic forces are to be measured, piezoelectric techniques also have a wide range of application. New piezoresistive devices for the measurement of force are promising in terms of high sensitivity and small size. Improved magnetostriction force sensors show promise for some applications. The study was also directed toward the develop ent of new or little-used techniques for the measurement of both force and displacement. A survey was made of known physical phenomena with a view toward finding those whic are not presently employed for the measurement of force or displacement but which might be adapted to this purpose.
