Automatic rotation equipment for tensile force transducers applying to 3 kN dead-weight type force standard machine

Automatic rotation equipment for tensile force transducers has been developed for the 3 kN dead-weight type force standard machine (DWM). ISO 376, the international standard concerning the calibration method of force proving instruments, requires measurements at three or more different rotational positions of a force transducer. Fully automatic calibration of the force transducer would be enabled when the force transducer could be automatically rotated. We had already developed automatic rotation equipment for compressive force transducers applying to the 3 kN DWM. By newly developing that for tensile force transducers, we realized fully automatic calibration of the both compressive and tensile force transducers using the 3 kN DWM.
