Abstract: A resonant sensor probe assembly includes a substrate formed from one or more dielectric materials and free-standing electrodes coupled with the substrate. The free-standing electrodes are configured to be placed into the fluid and to generate an electric field between the free-standing electrodes. A controller measures an impedance response of the sensor to the fluid between the electrodes to determine an aging effect of the sensor.

Abstract: A process of evaluating and reducing outages in a power plant comprises acquiring analytical data for a power plant and its components, acquiring failure modes regarding power plants, identifying and categorizing the acquired failure modes in association with the components of the power plant at various levels, evaluating and ranking the significance of each of the identified failure modes based on the analytical data, evaluating and ranking the analytical coverages of the identified failure modes based on the analytical data, and ranking and evaluating the components based on the significance and the analytical coverages of their associated failure modes. Based upon the determined significance and analytical coverages of identified failure modes, a power plant owner is able to evaluate the performance of a power plant at various levels, identify analytical gaps in reducing outages of the power plant, and enhance the performance of the power plant.

Abstract: This disclosure relates to modeling and visualization of vibration mechanics in residual space, and includes systems and methods for vibrational analysis. In one embodiment, a method includes acquiring, by at least one sensor, vibrational data and an operational mode of rotating equipment. The method may then proceed with determining, by an equipment controller communicatively coupled to the sensor, at least one vibrational vector based on the vibrational data. The method may determine, by the equipment controller and based on a model, an expected vibrational vector for the operational mode. The method may calculate, by the equipment controller, a residual vector as a difference between the vibrational vector and the expected vector. The method may also determine, by the equipment controller, at least one abnormality associated with the rotating equipment based on the residual vector.

Abstract: Streaming data at a sensor is sensed and received. The streaming data includes a plurality of observations. For a current observation in the plurality of observations, a health of the current observation is determined. Based upon the health of the current observation, a penalty is determined. A Sensor Health Index (SHI) for the current observation is obtained by aggregating the penalty with at least one SHI of one or more previous observations from the plurality of observations. An alarm is selectively generated based upon the SHI of the current observation.
