Characterization of Innovative Oil Level Sensors for Aerospace Applications

In this paper, experimental tests for optimal characterization of a new Capacitive Oil Level Sensor for aerospace applications are described. Both the sensing part and the conditioning circuit should meet strict constraints: this leads to put great attention to the mechanical characteristics of the probes. After a brief exposition of both the whole design aspects and the main advantages of using the proposed level sensing technique, the principal characterization results in terms of sensitivity, linearity, hysteresis, and settling time are reported.
