A NEW CONTROL- AND FEEDBACK-CONTROL-SYSTEM FOR FORCE AND TORQUE STANDARD MACHINES

Abstract:
A new control- and feedback-control-system for Force and Torque Standard Machines was developed in order to fulfil metrological and functional requirements. Different functionalities were programmed as independent modules, e.g. software modules for deadweight machines with sequential or exchange stack can be linked with modules for lever or hydraulic amplification. During the realisation of the concept, a strict requirement was that the application of the control system is possible to older, existing Standard Machines as well as to new Standard Machines, in order to allow retro-fits and upgrades. New features of the user interface allow easy connection of external devices like temperature chambers and the implementation of their functions in a calibration process without changing the software.
This paper outlines the concept of the system and gives details of how it was developed to become a universally applicable part in the GTM range of machines. Furthermore, some successful examples are given where more operational reliability and for this reason more measurement certainty has been reached by fitting the new system to older Standard Machines in the process of an upgrade.
