Abstract

Inventia face parte din categoria dispozitivelor de masurare a deplasarilor si prezinta un tip de dispozitive a carui functionare este determinata de controlul defazajului între semnalul furnizat de un generator si cel cules de la traductor. Generatorul este realizat cu un circuit astabil, iar traductorul îl constituie un circuit LC derivatie, functionînd aproape de rezonanta, variatia defazajului fiind determinata de modificarea inductivitatii inductorului.The invention is part of the device for measuring displacements and presents a type of devices whose operation is determined by the phase shift control between the signal provided by a generator and the one collected from the transducer. The generator is made with an astable circuit, and the transducer is an LC switching circuit, working near resonance, the variation of the phase shift being determined by the inductor inductance change.
