Abstract
The invention discloses a technology for filling a conducting medium into a single-hole closed small container. The conducting medium is filled into the single-hole closed small container through a vacuum filling system, and the vacuum filling system is formed through the connection of an evacuating subsystem, a filling subsystem and a blowing cleaning subsystem. The technology comprises the following steps: connecting the single-hole closed small container to be filled with the conducting medium to the vacuum filling system, evacuating through the evacuating subsystem, filling the conducting medium through the filling subsystem, taking down the single-hole closed small container filled with the conducting medium, and blowing off the conducting medium residual in a pipeline through the blowing cleaning subsystem. In the invention, the conducting medium can be fast filled after the formation of vacuum in the inner chamber of the single-hole closed small container; the inside and the outside of an elastic element in an elastic element sensor are simultaneously evacuated, so there is nearly no pressure difference, and the pressure difference in filling is small, thereby the elastic element is effectively protected; and there are no bubbles in the inner chamber of the elastic element sensor after the filling of the conducting medium, so the detection precision of the single-hole closed small container is guaranteed.
