1. A probe for detecting changes of a medium in a container, comprising:
a process connection for connecting the probe to the container, wherein the process connection is an integral part of a housing; and
the housing, comprising:
at least one microwave chip for generating microwaves;
at least one antenna connected with the at least one microwave chip, wherein the at least one antenna transmits and receives the microwaves in a direction of the medium;
an interface for connecting the probe to a higher-level unit; and
a data processing unit designed to receive data, including measurement data, from the higher-level unit via the interface and to transmit data to the higher-level unit, to activate the microwave chip, and to process signals that are dependent on the received microwaves,
wherein the process connection to a housing interior comprises an electrically conducting material, and the housing interior comprises an electrically conducting shield, and
wherein a diaphragm made of an electrically non-conducting material closes the probe toward the medium.
