CHARACTERISATION OF REFERENCE TORQUE WRENCHES BY THE IMGC SIX-COMPONENT CALIBRATION SYSTEM
Abstract
This paper describes the metrological characterisation of two Reference Torque Wrenches (RTW) of 100Nm and 500Nm capacity.
The characteristics of the torque sensors were evaluated by using the IMGC-CNR sixcomponent calibration system (EUROMET agree facility, project 113). The repeatability of the absolute variation of the output signal of the two TTS under the application of the different spurious components, referred to the R.O., is in general of the order of 5·10<sup>–5</sup>. The sensitivity to spurious components are normally better than 2·10<sup>–3</sup> of the nominal torque.
