Automatic control system for Torque National Standard

Abstract

The continuous development of the technology and the increase of its complexity demand wider measurement intervals, a greater exactness and a greater diversity of the standards used in order to establish the units or measuring systems. Torque metrology is of great importance and a magnitude is of common use for industry, technical development and research. The realization, quantification and dissemination of this magnitude are tasks assigned to the Metrology National Center (CENAM) Torque Laboratory, in Mexico. For the dissemination of this magnitude the Torque National Standard relies on a system, which, in its original design, was operated manually originating high consumption of man-hours in the development of a calibration. This work presents the standard automation and the benefits of the automatic control system.
