  • Patent number: 10598650
    Abstract: A system includes a sensor, one or more processors, a transmitter, and a capacitance control structure. The sensor is configured to contact a fluid and measure a characteristic of the fluid. The one or more processors are operably coupled to the sensor. The one or more processors are configured to generate one or more data signals representative of the characteristic of the fluid that is measured by the sensor. The transmitter is operably coupled to the one or more processors. The transmitter is configured to wirelessly communicate the one or more data signals to a remote reader. The capacitance control structure is configured to one or more of reduce or isolate sensor capacitance of the sensor from the one or more processors.

  • Publication number: 20200041480
    Abstract: A system includes a sensor configured to be disposed within a reservoir of a machine having moving parts that are lubricated by a liquid in the reservoir. The sensor is configured to obtain a measurement of the liquid that is representative of at least one of a quantity or quality of the liquid in the reservoir. The system also includes a device body operably coupled to the sensor. The device body has a processing unit that is operably coupled to the sensor and configured to generate first data signals representative of the measurement of the liquid. The device body also includes a transmitter that is configured to wirelessly communicate the first data signals to a remote reader.

  • Patent number: 9194758
    Abstract: Systems and methods of estimating an efficiency of a section of a steam turbine are disclosed. The systems and methods include determining a set of measurement data obtained directly from a set of sensors on the steam turbine, determining a set of derived data relating to measurements that cannot be obtained directly from the set of sensors, and estimating the efficiency of the section using the set of measurement data and the set of derived data. The systems and methods disclosed use physics-based models combined with nonlinear filtering techniques to estimate steam turbines' efficiencies when physical sensors are not available. These models capture the behavior of different components of the power plant, including all steam turbine sections, admission and crossover pipes, flow junctions, admission and control valves.
