Abstract
A fluid particle sensor for measuring and counting particles contained in a fluid. The fluid particle sensor comprises a first bundle of generally parallel elongated fiber optics, the first bundle having a longitudinal axis and opposite inside and outside ends, and a second bundle of generally parallel elongated fiber optics, the second bundle also having a longitudinal axis and opposite inside and outside ends. The sensor also comprises means for supporting the first and second bundles such that the longitudinal axes of the first and second bundles are approximately colinear, and such that the inside end of the second bundle is closely spaced apart from the inside end of the first bundle to form a gap through which the particle containing fluid flows. The sensor further comprises means for transmitting light to the outside end of the first bundle, and means for sensing the amount of light emitted from the outside end of the second bundle.
