ABSTRACT:
A force is translated into a pair of oppositely acting moments or electric signals up to a limited magnitude of that force by means of a folded beam structure which has a first leg presenting a first end of the folded beam structure, and a second leg, shorter than the first leg, presenting a second end of the beam structure. The first end is maintained relatively stationary and the force to be transduced is applied to the second end of the folded beam structure. The second leg is thereby moved with the applied force and there is thus applied on the first leg a first moment acting in a first portion of the first leg on one side of the second end and a second moment acting oppositely to the first moment in a second portion of the first leg on another side of the second end. According to the invention, overloading of the first leg is prevented by limiting the travel of the second leg against movement of that second leg by the applied force.
