A NEW ELECTRO-MECHANICAL OSCILLATOR SUITABLE TO METROLOGICAL APPLICATION

F. Cabiati, F. Vandoni

Abstract

An experimental electrometric set-up, conceived as a physical model of a metrological system for electric-watt realisation or Planck constant determination, has been operated in a persistent oscillatory mode. In this condition, the behaviour of a moving element in levitation and in vacuum is simulated. An experimental test of the relation between the frequency of the oscillation and the bias voltage of the fixed electrodes confirms the possibility of including such a relation in the set of equations from which the geometrical constant can be eliminated. Metrological exploitation of the investigated operating principle, is prospected for absolute voltage measurement.
