METHOD FOR DISPLACING CONTROLLED OBJECTS

摘要

The inventive method consists in exciting resonance oscillations of an electromagnetic field in an oscillating circuit which is provided with an inductance coil, measuring the capacitance of said oscillating circuit, the displacement of a controlled object being measured with the aid of the variation of the resonance oscillations of the oscillating circuit. An actuating object is arranged inside and /or outside the inductance coil and displaced with respect thereto, thereby modifying the capacitance of said coil by modifying the capacitive coupling between the different sections of the turns of the coil, the capacitance of the coil being the capacitance distributed along the winding thereof. Said invention extends the range of technical means for measuring the displacement of controlled objects.
