An Electromechanical Transducer
Joseph F. Engelberger, H. W. Kretsch · Transactions of the American Institute of Electrical Engineers · 1951
As the telemetering art progresses under the impetus of both aircraft and industrial needs, the requirement for accurate transducing becomes more and more important. This article describes a null-balance type of transducer which is inherently capable of achieving an accuracy comparable to that of present-day transmission links.
