Magnetic Analysis Corporation, a designer
and manufacturer of non-destructive
test systems for over 80 years, recently
supplied a multi-test eddy current/
ultrasonic system to inspect small
diameter (2.54mm to 31.75mm) titanium
bars and rods.
Testing criteria were AMS-2631B, Class
AA for the ultrasonic test (aerospace
specifications) and typical eddy current
inspection standards for the eddy
current test.
By combining eddy current and ultra-
sonic technology in a comprehensive
inspection system, superior test results
can be obtained as each technique is
used to detect the conditions that it is
best suited to find.
This particular system incorporates
Echomac® FD-4 ultrasonic instrumen-
tation, an Echomac Rotary which spins
the transducers and water couplant
around the bar, and a MultiMac eddy
current instrument and test coil.
The UT test uses one normal incidence
and two shear wave transducers to
inspect for surface and near-surface
defects such as spiral seams and light
cracks, inclusions and deep voids.
The eddy current single channel test
complements the UT test by detecting
some very small surface seams or pitting
that are poor reflectors of sound.
The test system also includes air
operated dual pinch stands designed
to drive and position the test material
accurately, a slide and elevate platform
to adjust the UT Rotary, a water
recirculation system for the couplant,
and automatic markers.
The system is mounted on a welded test
bench and ‘learn controls’ are included
to automatically adjust the timing based
on the initial test piece.

Test system for titanium rod
Falcon Topscan AWM system is a vision
inspection machine that allows fully
automatic thickness measurement
on insulating covers and non-metallic
sheathings of electric cables.
Developed by Falcon Instruments,
TopScan AWM is the evolution of the
profile projector or of the measuring
microscope, achieving the following
aims:
Measurement objectivity •
Results repeatability •
Time and manpower saving •
Ease of use •
Conformity with CEI 20-34/1-1 and •
with the international normative
The system measures the thickness of
insulating covers and sheathings, giving
the single thickness measurement. The
system is also capable of working with
varying height cable samples and with
a single parallel plane. This is made
possible by a particular disposition
of the camera. It also allows a double
interfacing level with the instrument:
the first level is for the line operators;
the second one is for a supervisor or
for those who are in charge of quality
laboratories.
All the systems of this product line have
been developed using the criterion of
the Falcon MMI user interface concept –
press a button and measure.
The instrument has the following
metrological characteristics:
Measurement repeatability: 1/4000 •
of the field of view. For example the
repeatability of the instrument with
a 20mm field of view is equivalent
to ±0.005mm.
Measurement reliability: 1/2000. •
For example, instrument reliability
with 20mm field of view is
equivalent to ±0.01mm.
