The studies of uncertainty of measurement and deviations of strain gauge torque transducers

This paper, presents the studies of the uncertainty of measurement and deviations of torque transducers. The studies have been executed using several numbers of torque transducers through period´s time with torque values. The strain gauge torque transducer has been calibrated using dead weights (0.5-10Kg) and torque values (50Nm) at Sirte University Laboratory, Libya. For this study, torque standard machine of capacity (2000Nm) has been used. Moreover, for this research a number of torque transducers with capacities (10-1000Nm) have been used as references that were done at the National Physics Laboratory, India. The deviation from the typical value is found maximum in 2011. Also the torque transducer of (50Nm) offers that the uncertainty of measurement of the torque transmission is higher in 2011.
