Capacitive oil deterioration and contamination sensor

摘要: An oil deterioration and contamination sensor includes a housing, substrate with first capacitive plate mounted within the second to housing close plate, total reference capacitor which an external fixed capacitor. The is such that at least one fluid including freely circulates gap between plates thereby defining respective capacitances of provide indication dielectric constant gap. also circuitry for generating detection adapted receive process generate when exceeds predetermined value or rate change in excess maximum ordinary change.
