TITLE: Thickness measurement of pipe walls from austenitic-class steel by a
method using an applied induction coil

TEXT: The paper considers the problem of thickness measurements of pipe
walls by the method of eddy,currents with the use of an applied induction coil.
The thickness gauge consists of a generator, induction :iensors, amplifier,
indicating instrument (microvoltmeter),and an automation unit. The description
of the principle of operation of the instrument and the circuits of the main
parts of the instrument are given. The thickness gauge makes it possible to
measure semi-automatically, under shop conditions, the viall-thickness and the
variation in wall thickness of thin-walled and extra-thin walled pipes from
austenitic steels. The dimensions of the pipes being controlled constitute
