Abstract
A fluid contamination analyzer employs one or more MEMS-based sensors. The sensors are incorporated into probes or alternatively may be employed in an in-line analyzer residing in the fluid. The sensors, which can be selective to detect a distinct contaminant within the fluid, sense an impedance of the fluid, which is a function of its contamination and communicates the impedance to analysis circuitry.
