ABSTRACT:
A force transducer having a vibratory member either a beam or a string and means for effectively isolating the vibratory member from its end mounts over the range of its operating frequencies to eliminate energy loss to the mounts. The axial stresses, either tension or compression, are directly transferred to the vibratory member to affect its natural resonant frequency. Isolation at vibration frequencies is effected by the cooperation of combined isolator masses and isolator springs with the vibratory member. The isolator masses comprise two bars extending from each end support of the vibratory member, each being coextensive with a portion of the support member. The pairs of masses are axially separated. The isolator springs comprise two single thin, spaced resilient members, each isolator spring connecting a single end support of the member and a single transducer end mount.
