Torque being a very important physical parameter, plays a very vital role in various applications like aviation, automobile, power and agriculture industries. Torque is, generally, measured by mechanical type torque meters/torque wrenches, having higher uncertainty. These mechanical type torque meters/torque wrenches need to be calibrated using strain gauged torque transducers. Hence, there is acute thrust over development of precise and reliable strain gauge based torque transducers. In the present work, a torque transducer of capacity 5 Nm has been studied. The torque transducer has been metrologically characterized against the standard torque machine (bmc = +/-0.05% at k = 2) using the standard calibration procedure based on standard BS 7882:2008. The uncertainty of measurement of the torque transducer is +/- 0.06% (at k = 2).
