  • Apparatus for detecting impurities in a fluid circuit using optical fibers and a magnet
    Patent number: 5173600
    Abstract: The apparatus for detecting impurities in a fluid circuit has a body member associated with a fluid conduit or reservoir which defines a detection zone. A magnet is associated with the body member and communicates with the fluid in the detection zone to attract metallic impurities. Fiber optic members extend from opposite sides of the detection zone, with one of the fiber optic members associated with a light source and the other fiber optic member associated with a light sensor. The light is transmitted by the first fiber optic member into the fluid in the detection zone. The light passing through the fluid is transmitted by the second fiber optic member to the light sensor.
