Abstract
A fill level measuring device for capacitive fill level measurement and/or travel time fill level measurement of a fill substance in a container. The measuring device has a coaxial measuring probe, whose inner conductor is galvanically isolated from its shield conductor, and whose shield conductor lies electrically at a reference potential. The device additionally includes: a securement apparatus lying electrically at a reference potential and serving for securement of the measuring device on a container opening equipped with a counterpart of the securement apparatus; and a washer made of an electrically conductive material and clamped in measurement operation between the securement apparatus and the counterpart. The inner conductor is completely surrounded in measurement operation by an insulating layer and passes through the washer into the container. The device additionally includes an insulating body adjoining the insulating layer and coaxially surrounding the inner conductor. The insulating body has a washer-shaped section clamped between the securement apparatus and the washer. The shield conductor coaxially surrounds the inner conductor and is connected mechanically and in an electrically conducting manner with the washer. At least one electrical contact element is affixed in the washer outside of a region of such covered by the insulating body and on a spring element. Via the contact element and the washer, the shield conductor is connected in an electrically conducting manner to the securement apparatus.
