Jittakant Intiang, E. DeGollier, Richard Rakowski, Barry E. Jones & A. Cheshmehdoost
This paper will describe progress in the development of miniature metallic resonant Triple Beam Tuning Fork (TBTF) sensors for torque measurement applications. For high accuracy any torque transducer using these sensors ought to have low sensitivity to parasitic influences such as bending moments and lateral forces, which can only be achieved with reduced sizes. Compared to the original 15.5mm length vibrating tine, the lateral forces are reduced by 52% for a 9mm tine length and...
