Abstract: A transducer has a body of ferromagnetic material to which force to be measured is applied to produce, by magnetostriction, changed distribution of magnetic flux induced in the body by an a.c. energized primary embracing it. The body has a hole large enough to insure high stress concentrations upon application of force. An even number of secondaries are wound through smaller holes and around edge portions of the body. Half of the secondaries embrace zones of tension stress, the other half zones of compression stress.
