Patent ID: 8365592

Claim:
A measuring probe for a measuring device for ascertaining and monitoring fill level of a medium in a container is composed essentially of two regions, a measurement-active region, and a measurement-inactive region, comprising: a probe holding element in said measurement-inactive region of the measuring probe, which is mounted on the container and which defines an axial bore; and a probe element, which is secured in an axial bore of said probe holding element by means of a releasable securement means and which represents said measurement-active region for that part of said probe element which is outside said axial bore in said probe holding element of the measuring probe; a first cavity provided in said axial bore of said probe holding element; a second cavity on said probe element; and a locking element provided, which, in a final position of the mounting of said probe element in said probe holding element, protrudes into said first cavity and into the oppositely lying second cavity on said probe element and, thus, forms an axial locking, in which said releasable securement means, said first cavity, said second cavity and said locking element are so embodied, that no disturbance reflections of the high-frequency measuring signal are created in said measurement-inactive region of the measuring probe in the form of a coaxial conduction system due to resistance changes from geometrical changes.
