COMBINATION CONTAMINANT SIZE AND NATURE SENSING SYSTEM AND METHOD FOR DIAGNOSING CONTAMINATION ISSUES IN FLUIDS
First Claim
Patent Images
1. A method of diagnosing contamination issues in a fluid, comprising:
- directing a flow of a fluid sample into a fluid passage;
directing light into the fluid sample flowing in the fluid passage; and
using two sensors to obtain data resulting from the light impinging on contaminant particles in the fluid sample, and each sensor is calibrated using the same calibration technique.

Abstract
Systems and methods used to monitor a fluid where it is important to know the size, concentration and nature of particulates in the fluid. For example, the systems and method can be used to diagnose contamination issues in fluids such as fuel, lubrication, power transfer, heat exchange or other fluids in fluid systems, for example diesel engines or hydraulic systems, where contaminant particles in the fluids are of concern.
