A sensor assembly for use in a system is provided. The sensor assembly includes at least one probe for detecting the presence of a material within the system, wherein the probe includes a microwave emitter. The microwave emitter generates at least one electromagnetic field from at least one microwave signal, wherein a loading is induced to the microwave emitter when the material interacts with the electromagnetic field. A data conduit is coupled to the microwave emitter, wherein at least one loading signal representative of the loading is reflected within the data conduit from the microwave emitter. At least one signal processing device is coupled to the microwave emitter via the data conduit. The signal processing device is configured to receive the loading signal and to generate an electrical output that is representative of the presence of the material, wherein the electrical output is usable by an operator and/or the system. |
