Electric fill level gauge

Electrical fill level measuring device (1) for measuring a fill level of a medium (M) in a containment (B), comprising:

• an electrically conductive probe (10) adapted for conducting an electric signal, wherein the probe is adapted to be immersed in the medium;
• an electronic measuring/operating circuit (20) adapted for producing and evaluating electric signals as well as for providing fill level measured values;
• a housing (30), in which, for example, the electronic measuring/operating circuit is arranged;
• secured to the housing, a process connection (40), which is adapted to support the probe radially, wherein the probe extends sectionally inwardly via an open end (41) of the process connection into a lumen (42) of the process connection;
• wherein the probe (10) is supported radially by the process connection by means of a conical seal (50),
• wherein an interior surface (43) of the process connection in the region of the open end has a conical form, wherein an inner diameter decreases toward the open end, wherein the conical seal is compressed between the conical interior surface and the probe,
• wherein a spring mechanism (60) is adapted to push against the conical seal axially in the direction of the open end,
• characterized in that
• the probe has a first probe part (11) and a second probe part (12), which probe parts are joined together, wherein the first probe part is arranged in the lumen and provides an engagement surface (11.1) for the spring mechanism, and wherein the second probe part is adapted to be immersed in the medium.
