Linearizing mechanism for a vibrating beam force transducer
First Claim
Patent Images
1. A force transducer comprising a vibrating beam having a longitudinal axis and adapted to vibrate in a plane including the axis;
- a supporting element secured to each end of the beam and extending in both directions tranversely of the axis;
a pair of end mounts;
axially complaint isolator spring means each having multiple sections of unbalanced spring rates and extending between each end mount and a corresponding support element for transmitting axial forces from the end mounts to the beam along the longitudinal axis thereof; and
a pair of parallel spaced isolator means connected between each respective support element and sections of a corresponding spring means;
whereby the unbalanced spring rates of the spring means induce precise beam bending due to applied vibrational forces thereby substantially cancelling undesirable non-linear effects.

Abstract
A single beam force transducer is provided with integrally affixed isolation springs which are axially compliant and unbalanced in their spring rates so as to induce beam bending due to applied tension and compression. The amount of bending introduced due to applied tension will be of a precise magnitude so as to substantially cancel undesirable non-linear vibration effects.
