ABSTRACT:
A fill level measuring device for ascertaining and monitoring fill level of a medium in the process space of a container by means of a microwave travel time measuring method. The device includes: measurement transmitter; and an antenna unit, which is constructed at least of a hollow conductor and a radiating element, wherein a process isolation element is inserted into the hollow conductor for process isolation between measurement transmitter and the process contacting, radiating element. The process isolation element is made of a ceramic material and includes at least one glass layer, via which the process isolation element is directly glass bonded in the hollow conductor in a glass bonding region.
