<p>A device for making resistors of insulated wire comprises a mechanism (9) receiving the wire (3) reeled off from the resistor (4) placed in a fixing mechanism (5); a current-feeding and a current-collecting electrode (2) intended for resistance and capacitive coupling of the reeled off wire (3) with a metering circuit and with a harmonic osicillator (1); electrical contact elements (6) and (8) of the mechanisms (5) and (9); an emitter follower (10) its potential input being connected to the electrical contact element (6) and its output being connected to the potential input of a phase amplifier-inverter (11), the output of the latter being connected to a limiting amplifier (12) and to a precise voltage divider (14), one of the poles of which is connected, through a sample resistor (13), to the electrical contact element (8). The common point of the precise divider (14) and the electrical contact element (8) are connected, through a differential amplifier (17) having a high-resistance input, to a phase-sensitive indicator (18), the reference signal inputs of the latter being connected to the outputs of the limiting amplifier (12) and the output being connected, through unit (19) of control of a drive (20), to the drive (20), cinematically connected with the mechanism (9) of receipt of the wire. </p> |
