    • Sensor assemblies used to detect the proximity of a material to a microwave element are disclosed. One example sensor assembly includes a signal generator configured to generate at least one microwave signal, a coupler connected to the signal generator, a microwave element coupled to the coupler, and a processing module connected to the coupler. The microwave element is configured to generate an electromagnetic field as a function of said at least one microwave signal. The microwave element is structured to reflect a loading signal to said coupler when a material interacts with the electromagnetic field. The processing module is configured to process the loading signal with a reference signal to generate a data signal representative of the proximity of the material to the microwave element. The data signal defines a sub-microwave frequency.
    • 公开了用于检测材料与微波元件的接近度的传感器组件。 一个示例传感器组件包括被配置为产生至少一个微波信号的信号发生器,连接到信号发生器的耦合器,耦合到耦合器的微波元件以及连接到耦合器的处理模块。 微波元件被配置为产生作为所述至少一个微波信号的函数的电磁场。 当材料与电磁场相互作用时,微波元件构造成将加载信号反映到所述耦合器。 处理模块被配置为用参考信号处理加载信号以产生表示材料与微波元件的接近度的数据信号。 数据信号定义了一个亚微波频率。
