DEVELOPMENT OF THE NEW LNE 5 kN·m DEADWEIGHT TORQUE STANDARD MACHINE

Philippe Averlant, Pascal Lacipiere, Jean-Marie David
Abstract:
This paper describes the new LNE 5 kN.m deadweight torque standard bench. Information on the design, development, and commissioning of this standard are given. Its design is described focusing on mechanical and metrological characteristics. In particular, three components, developed by LNE, are described: First, the double arm lever, one for deadweight force transmission and the other for localization of this force Then, the air bearing based on used of porous material. Finally, the system should enable us to avoid the wrinkling of the tape related to the positioning of the force at the extremity of the lever arm. The attention given to these elements enables to consider uncertainties compatible with the primary national reference function.
