On-line sensors based on optical, ultrasonic, electostatic and inductive principles are evaluated for use in determination of wear in oil systems of aircraft GTEs. This application is limited due to contraints of the high oil flow rate (40-60 L/min) and the flow diameter of 20-25 mm. Under such conditions, most sensors are unable to function efficiently and give incorrect readings. As such, creating on-line wear evaluation systems remains hardware-limited. Decrease of detection limit of non-ferrious particles for inductive type sensors is a possible way to solve the issue.
