MINIATURE SENSOR FOR LUBRICANT ANALYSIS

摘要

A fluid contamination analyzer (90) accepts data from a sensor array (94). T he fluid is affected by a magnetic field stimulus (96) from a control driver (98). Alternatively, an electrostatic field exciter may be used. The sensors impedance as a function of field strength is an indication of the particles characteristics, when multiple sensors are separated by substantial distance s, a system of communication links is used and the information is digested at a central location.
