In the presented paper, an original solution to the system maintaining vibrations of a wire transducer, which has been based upon the phenomenon of self-oscillation, is described. The vibrations generated in this manner do not fade in time, are resistant to disturbances and allow measurement of the signal rapidly changing in time. The dynamic equations and numerical simulations of motion of the wire interconnected with the van der Pol oscillator are presented. Based on the conceptual model, a laboratory stand has been built, which served to verify properties of the presented solution and possibilities of useful applications.
