Title: The Innovative Contributions of Robert W. Kempster
Introduction
Robert W. Kempster is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of particle detection in fluids, holding a total of 4 patents. His work focuses on developing methods and apparatuses that enhance the detection of metallic particles in various fluid lines.
Latest Patents
Kempster's latest patents include a method and apparatus for detecting particles in a fluid using coils. This innovative device is designed to detect the presence of metallic particles in fluid lines. The fluid flows through a specially constructed former, which is wound with a coil assembly comprising a sensor coil flanked by two field coils. The design ensures that pressure fluctuations in the fluid do not adversely affect the readings of the coils. The field coils are driven by a high-frequency signal from a crystal oscillator, and their opposing windings cancel out the magnetic field in the plane of the sense coil. When a ferromagnetic or conductive particle passes through, it disturbs the coupling in the sense coil, generating a characteristic signature that can be analyzed to distinguish between ferromagnetic and non-ferromagnetic conductive particles.
