Abstract

The present paper describes the long term stability of the main metrological characteristics of the two reference transducers of 3 MN and 9 MN together with the relevant uncertainties evaluated from the measurements carried out by INRIM and PTB by bilateral comparisons. In June 2004, the new INRIM – 3 MN build-up system (BU), the 9 MN and 5 MN transducers were also intercompared, by using the PTB 2 MN DWM and the 16.5 MN Hydraulic Multiplication Machines (HMM). The main results are reported. Furthermore long term investigations carried out over 20 years and the work obtained within a EUROMET project are described.
