COMPARISON MEASUREMENTS OF MIKES-RAUTE 20 kN·m TORQUE REFERENCE DEVICE WITH THE PTB

Aimo Pusa, Dirk Röske, Michael Sachs

Abstract

This article deals with the vertical 20 kN·m torque reference calibration device newly built by MIKES- RAUTE. It widens the possibilities of the MIKES-RAUTE Mass and Force Laboratory in the field of torque calibrations from 2 kN·m up to 20 kN·m. A brief overview about the construction and setup of the device is included in this report. Also some information about the applied calibration process is given. The main part of this article describes comparison measurements with the PTB, Germany, from summer 2004 and presents their results. They show that the device will attain an uncertainty level of 5·10^-4 or better over the entire measurement range.
