OIL LINE MAGNETIC METAL CHIP DETECTOR Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: two permanent magnets are enclosed in dielectric bush. Electric circuit located in housing has voltage source, indicator lamp and chip sensors. Permanent magnets are located in parallel with clearance and ends of unlike poles are brought out to oil line. Ends of magnets in oil line are sunken relative to end of bush forming chamber for accumulating chips. Sensors are made in form of electrodes located in oil line in immediate proximity with ends of unlike poles. EFFECT: enhanced efficiency. 2 dwg
