The Design, Development and Commissioning of a 2kNm Torque Standard Machine

January 02, 2017

This paper describes NPL’s 2 kN·m torque machine — Now at Morehouse Instrument Company — a lever deadweight machine with a vertical torque axis and an uncertainty of ±0.002 %. Despite the greater difficulty in applying torques to a vertically mounted transducer, this design was selected as it enables a symmetric “pure” torque to be applied. In addition, this design provides adaptability, enabling comparisons with the application of asymmetric torque and “on-thefly” torque calibrations to be studied.
