Abstract

A multi-element fluid sensor system having a distributed sensor configuration for determining the health state of a fluid. The sensor system includes at least two sensors for collecting data relating to a particular parameter (e.g., pH, temperature, electrical conductivity, chemistry, viscosity) of the fluid. The at least two sensors may be integrated onto a semiconductor base so as to provide for a micro sensor for in situ monitoring of the fluid. The system also includes a data fusion processor operatively coupled to the at least two sensors. The data fusion processor processes the fluid data to at least compensate for information fragmentation attributed to using the at least two sensors. The data fusion processor may condense the data, combine the data, evaluate the data and interpret the data.
