Abstract

The invention relates to the field of electrical measurements and may be used for measuring the linear resistance of the glass-insulated wire in the casting process.The device comprises a measuring signal generator, having one output terminal connected to the common wire, a capacitance contact, placed in immediate proximity to the measured wire, reeled on the bobbin, a capacitor, having one pole connected to the capacitance contact and the second pole - to the second output terminal of the generator, an amplifier, having its input connected to the capacitance contact, a negative resistance converter, having one output terminal connected to the common wire, a controllable resistor, connected to the input terminals of the negative resistance converter, a phase-sensitive null detector, having its signal input connected to the output of the amplifier and its reference input to the point of the negative resistance converter circuit, into which the signal has the same phase as in the measured wire, as well as a null-indicator, connected to the output of the null detector. The bobbin is made of metal and it is electrically connected to the second output terminal of the negative resistance converter.
