This invention relates to the measuring technique and electronic devices. It is designed for the transformation of fluctuations of electric signals from the inductive measuring convector into frequency fluctuations. The purpose of this invention is to extend application options of the inductive measuring convector, increase its accuracy, improve transformation linearity, and decrease power consumption. The invention is essentially complementary to the generator's circuit with an operational amplifier (1), whose inverting input is equipped with the measuring convector's inductive sensor (L) and the amplifier's feedback resistor (R1), as shown in Fig. 1., in addition to a threshold voltage element (2), and a resistive voltage terminator (R2). Additionally, the circuit can be equipped with a switchboard and condenser, which allows the coupling of the described generator with the differential inductive measuring convector and homopolar power supply.<IMAGE>
