ABSTRACT:
An apparatus is adapted to detect particles within a fluid. The apparatus includes first and second electrodes within a housing. The first and second electrodes form a "V" shaped recess. A magnet is positioned within the housing to attract ferrous particles into the recess. The resistance between the first and second electrodes is measured as an indication of particles within the fluid.
