    • A sensor for sensing a displacement in a mechanical system using radar utilizes a miniaturized radar transceiver formed, typically, on a silicon chip. The transceiver is mounted to a fixed surface that senses a displacement of a moving surface. The moving surface is typically located in mechanical communication with a system to be sensed. By using appropriate translating circuitry, an accurate determination of the nature of displacement of the mechanical system can be made. Mechanical systems sensed can include rotating and sliding components such as motors, valves and pressure gauges. Sensors according to this invention are highly accurate and reliable.
    • 用于使用雷达感测机械系统中的位移的传感器利用通常形成在硅芯片上的小型化雷达收发器。 收发器安装到感测移动表面位移的固定表面。 移动表面通常位于与要感测的系统的机械通信中。 通过使用适当的平移电路,可以准确地确定机械系统的位移性质。 感测到的机械系统可以包括旋转和滑动部件,例如马达,阀门和压力计。 根据本发明的传感器是高度准确和可靠的。
