ABSTRACT: The construction and use of an'tectrommetic "Intrasc9pe" to described.
Ferromagnetic tubes imre Inspected for artIfIcia, ly-induced and natural defects. by
transferrivg 2-dimenaLonal magnetic relief patterns of the defects to electrochemical
paper. Schematic drawings of the Intrascope components and their circuitry are present
ad, The original signal Is emitted by an inductive probe transmitter,.having a range
of sensitivity of 0.015-0.1 Woe relative to the external magnetic field. After boost
Ing, the signal to sent through an amplitude modulator, a power amplifier, a rectifier
a signal synthesizer (the topograph) and finally. a recorder. Circumferential scanning
of tubes with an outer diameter of 57.6 = was done by rotating them at 2 rev/sec. In
the longitudinal direction# the bqe scale vas usually 1i1. In the transverse direc-
tion the image scale m was given by the formula
