Electronic device for aeronautic application, has sensor with small diameter coils, and electronic circuit with integrator circuit measuring phase difference between voltage and current circulating in oscillating circuit

摘要

The device has a resistor (12) and a capacitor (11) mounted in series with connection terminals (13) to constitute an oscillating circuit when an induction sensor (20) having small diameter coils (21) is electrically connected to the terminals. An electronic circuit (15) has an integrator circuit to measure phase difference between a voltage and a current circulating in the oscillating circuit.
