Abstract:
Open-ended Terms Displacement transducers. A study was made of electrical methods of measurement of linear and angular displacement. The study was directed toward assessing the present state of the art and providing guides toward new or improve techniques applicable to advanced military flight vehicles, particularly in regard to environmental extremes. For linear displacement measurement, it was found that existing linear variable differential transformer techniques are suitable foure and nuclear radiation environments expected to be encountered. The principles of the linear variable differential transformer can be extended to still higher temperature applications by use of a conductive rather than ferromagnetic core, i.e., eddy current techniques, to avoid the Curie temperature limitation of magnetic material, at the expense of more elaborate and sensitive auxiliary circuitry.
