Intelligent fluid sensor for machinery diagnostics, prognostics, and control
ActiveUS7581434B1Minimizes bandwidth requirementImprove performanceFlow propertiesLubrication indication devicesControl systemEngineering
A system that facilitates device and / or machinery diagnostics, prognostics and control by way of condition sensing, such as sensing the condition of the device and / or a fluid of the device (e.g., fluid health indicators). The system can employ a plurality of sensors to determine a current state and estimate a future state of the fluid and / or device, as well as providing control of the device, e.g., in order to increase the remaining useful life of the fluid and / or operation of the device. The sensors can communicate wirelessly with each other, with the device, and / or with a central control system that provides, e.g., sensor fusion, prognostics and control integration. In addition, the sensors can be powered locally based upon the physical or chemical properties of the environment.
