  • Apparatus for measuring magnetic particles suspended in a fluid based on fluctuations in an induced voltage
    Patent number: 5001424
    Abstract: An apparatus for detecting magnetic particles suspended in a liquid, such as particles suspended in lubricating oil flowing through an engine. The oil is caused to pass through the area coupling two or more coils while the mutual inductance of the coils is monitored. When a magnetic particle enters the area coupling the coils, the mutual inductance of the coils will increase, thereby indicating the presence of the particle.
