Abstract
Disclosed is an actuator level detection system of an aircraft. The system includes an actuator containing fluid that defines a resistivity and including a first contact point and a second contact point. The system includes a first contactor disposed about the actuator cooperating with the first contact point to define a first contact resistance that includes the resistivity. The system includes sensor circuitry includes a conductive path defining a conductive path resistance, between the first contact point and the second contact point. The sensor circuitry has a total resistance that includes the first contact resistance and the conductive path resistance.
