1939 U. Lamm in ASEA Jrnl. XVI. 71/2 We should like to introduce some explanation of the word ‘transductor’... The purpose of this word is actually to express the idea that as regards the mutual action between its two windings the apparatus resembles a transformer whilst, however, at the same time functioning in the A.C. circuit as a reactor or inductor, i.e. a conductor.
1975 IEEE Trans. Nucl. Sci. 22 1277/1 At Fermilab, transductors are used as current measuring devices in the main accelerator quadrupole power supply feedback loop.
