Dynamic repeatability and linearity of the transducer are presented in this paper at first, which includes dynamic calibration, modeling, calculation methods of dynamic performance, repeatability and linearity on the base of a lot of dynamic calibration experiments. The dynamic performance improved method of a force transducer (load cell) which uses the active analog filter is presented in the second part, including a new design method of the dynamic compensated analog filter, dynamic mathematical model (continuous transfer function) of the calibrated force transducer and its analog simulator, the circuit diagram of the designed dynamic compensated filter, simulated and experimental results of the dynamic performance improvement in the time domain and frequency domain.
