Claim:
A guide-through assembly for a filling level sensor attachable in or on a vessel, comprising: a process connection to connect to a vessel and including an interior circumferential surface, an interior conductor arranged within the process connection, a solid-state insulating sealing body through which the interior conductor extends and circumferentially surrounds the interior conductor in a positive sealing engagement and is fitted into the process connection in a positive sealing engagement, the insulating sealing body comprising an exterior circumferential surface; wherein both the interior circumferential surface of the process connection and the exterior circumferential surface of the insulating sealing body have a tapered section; wherein the tapered section of the insulating sealing body is fixed into the tapered section of the process connection and the entire exterior circumferential surface of the insulating sealing body is in direct contact with some portion of the interior circumference surface of the process connection; wherein the interior circumferential surface of the process connection and the exterior circumferential surface of the insulating sealing body are wedged against each other in a gas-tight manner; wherein the tapered sections of both the interior circumferential surface of the process connection and the exterior circumferential surface of the insulating sealing body only taper towards the interior of the vessel.
