| Zusammenfassung | This paper present a new method for calibrating piezoelectric force tranducers with static forces. Load cycles with prilgrim-steps and a special evaluation of the measuring results permit the determination of transducer coefficients that are independent of the linear drift of the charge amplifier. Consequently, the coefficients are independent of the measurement time and the time of load change of the force standard machine in use. It is shown that the new calibration method contributes essentially reducing the uncertainty of piezoelectric force transducers that are used in quasistatic and dynamic precision force measurements. |
