Performance of force comparator with reference to tuning-fork type force transducer

  • Abstract:
    A force comparator was constructed using a conventional screw-driving type uniaxial testing machine. A tuning-fork type force transducer was used as the reference. A strain-gauge type force transducer was calibrated with the comparator using springs and bearings to relax eccentric forces and moments. In comparison with a conventional dead-weight type force standard machine, deviation of up to only 1 mN at the rated capacity of 50 N was observed. There were still some limitations in terms of force controlability and obstructive eccentric forces; nevertheless, the force comparator exhibited favorable performance for the calibration of commercial force transducers. The tuning-fork type force transducer was suitable as the reference because of its long-term sensitivity stability and small hysteresis.
