Abstract
An electrically conductive particle detector that includes a hollow spool or sleeve of insulating material having an open end, a sidewall and a circumferential array of elongated fluid passages that extend radially through the sidewall. A pair of internested helical conductors are mounted in corresponding helical grooves on the interior of the sleeve sidewall, with helical reaches of the conductors spaced from each other by the sleeve. Electrical circuitry is connected to the conductors for detecting impingement of a conductive particle that bridges adjacent reaches of the conductors in fluid that flows through the sleeve. A perforated strainer is carried by the sleeve spaced from the conductors for removing particles in the fluid that flows through the sleeve.
