The invention relates to the measurement technology and may be used for casting conductors or semiconductors in isolation.The method for measuring the cross-section of a wire in the casting process, for example a microwire in glass insulation, consists in its extraction from a metal melt, winding of the cast microwire on a metal frame, forming a spool with cast microwire with the equivalent electrical impedance Zb, measurement of microwire cross-section and its control by controlling the microwire casting mode. Measurement of microwire cross-section is carried out by means of a resistor with resistance R, connected in series with the spool with microwire and the portion of measured microwire of a fixed length l, linear resistance r and integral resistance rl, forming a series circuit of total resistance R+Zb+rl. |
