Device and method for filling of hydraulic pressure measurement mechanisms

摘要

For avoiding the evaporation of volatile components of a fill oil and for avoiding contamination of the fill oil with ambient air, a method for the filling of hydraulic pressure measurement mechanisms by means of a readied filling chamber. The method includes the following steps: (I) Evacuating the filling chamber by means of a vacuum pump over a first path of a first conductivity, extending between the vacuum chamber and the vacuum pump; (II) ending the evacuation of the filling chamber over the first path; (III) continued evacuating of the filling chamber by means of the pump over a second path of a second conductivity, extending between the filling chamber and the vacuum pump, wherein the second conductivity is smaller than the first conductivity; (IV) feeding the fill oil into the evacuated fill chamber and (V) filling the measurement mechanisms.
