Abstract
The invention concerns an automated method for producing a blown glass body, in particular a glass wall of an electrochemical sensor, wherein an immersion tube (), through which air or gas can flow, is immersed into molten glass an amount of molten glass from the molten glass mass, and wherein the () and subsequently withdrawn to remove removed glass is blown into the form of the glass body to be produced by means of the air or gas flowing through the immersion tube (), comprising the following features:—the position of the surface () of the molten glass () in the adjustment direction of the immersion tube () is determined; an adjustment means () for the immersion tube () is controlled in correspondence with the determined position of the surface () such that the free end of the immersion tube is first immersed into the molten glass mass () up to a certain predetermined immersion depth (h) of molten glass; and then removed thereby retaining a predetermined amount—following removal from the molten glass, the immersion tube () is loaded with a blow pressure along a blow pressure curve p(t) stored in a computer thereby blowing the glass body into the desired shape. This provides reproducible and automated production of the glass body.
