Abstract

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 by 80% for 6mm tine. High stiffness of these metallic resonant sensors will additionally reduce the occurrence of wrong measurement values as a result of overload damage. To support the use of these sensors in industrial applications a transfer standard using this technology is recommended.
