A method of measuring ferromagnetic wear particle based on Hall effect

In order to detection the content of ferromagnetic wear particles in lubricating oils, a kind of ferromagnetic wear particles detector was designed according to the principle of Hall effect and high-gradient magnetic separation. Appropriate Hall sensor and post-processing circuit were determined. It is ease to catch, detection and analyse ferromagnetic wear particles in lubricating oils using this ferromagnetic wear particles detector. It provides a new method for machine condition monitoring and fault diagnosis. The principle, structure,circuit and Hall sensor are presented.
