PARTICLE COUNTER AND CLASSIFICATION SYSTEM

摘要

A particle counter and classification system including an imaging subsystem configured to determine the size and morphology of particles above a predetermined size in a fluid in a sample cell. A first stage magnetometer sensor subsystem is tuned to detect and determine the size of ferrous and/or conducting particles. An optional second stage magnetometer sensor subsystem is tuned to detect the overall ferrous particle content of the fluid. A processor subsystem is configured to calculate and report the number of particles in the fluid in a plurality of size ranges, their morphology, their classification as a particular particle type according to their characteristic morphology, the number of ferrous and/or conducting particles, and the overall ferrous content of the fluid.

1. A particle counter and classification system comprising:
a detector subsystem configured to determine the size of particles above a predetermined size in a fluid in a sample cell; a first stage magnetometer sensor subsystem for the fluid tuned to detect and determine the size of ferrous and/or conducting particles in said fluid above said predetermined size; a second stage magnetometer sensor subsystem for said fluid tuned to detect the overall ferrous particle content of the fluid; and a processor subsystem, responsive to the detector subsystem, the first stage magnetometer sensor subsystem, and the second stage magnetometer sensor subsystem, configured to calculate and report the number of particles in the fluid in a plurality of size ranges, the number of ferrous and/or conducting particles in said size ranges, and the overall ferrous content of the fluid.
