Liquid contaminant sensor system and method

Abstract

A liquid contaminant sensor system and method. An example system includes at least one light source. The example system includes at least one light detector to receive a light signal from the at least one light source. The example system includes a signal processor to compare the light signal received at the at least one light detector with a reference signal and determine if a particle is present in a liquid. An example liquid contaminant sensor method includes emitting a light into a detection path and a reference path, detecting a light signal from the detection path and the reference path, and comparing the light signal with a reference signal to determine if a particle is present in a fluid. In an example, a fluid path is split into a detection path and a reference path. In another example, the fluid path includes both the detection path and reference path.
