Advanced ultrasonic
thickness gauge
OLYMPUS NDT has introduced
the handheld 45MG ultrasonic
thickness gauge, an advanced, small-
sized thickness gauge packed with
measurement features and software
options. The instrument is compatible
with the complete range of Olympus dual
element and single element transducers,
making it an all-in-one solution for
thickness gauge applications ranging
from wall-thinning measurements of
internally corroded pipes using dual
element probes, to precise thickness
measurements of thin materials using
single element transducers. Ultrasonic
thickness measurements are accurate,
reliable and repeatable, and instant
readings can be achieved from one side
of a material, making destruction of the
part unnecessary.
The 45MG features powerful standard
thickness measurement features and
specialised software options. For
corrosion detection applications, the
gauge offers optional Thru-Coat® and
Echo-to-Echo technology for measuring
thickness with no need to remove paint
and coatings, and time-based B-scan,
which converts live thickness readings
into cross-sectional drawings. When
used with the code-activated single
element transducer option, the 45MG is
capable of making accurate thickness
measurements on many materials,
including metals, plastics, composites,
glass and ceramics. This feature allows
for very precise measurements with a
resolution of 0.0001" or 0.001mm.
The optional single element High
Penetration feature enables the
gauge to take measurements on
very thick or highly attenuating
materials, such as cast metals,
rubber and fibreglass.
The Olympus 45MG is built
for use in a wide range of weather
conditions and difficult inspection
environments. Its sealed case is
designed to meet IP67 requirements in
order to withstand the rigours of very wet
or dusty environments. The transflective
colour LCD with QVGA resolution
provides readability, from bright sunlight
to complete darkness.
The 45MG features a simple keypad
that can be operated with either the
left or right hand for easy access to
all important gauge functions. It is
designed for use with all single and dual
element thickness gauge transducers,
and offers standard features such
as sound velocity readings, time-of-
flight readings, differential mode, and
reduction rate mode.
An optional data logger provides
internal storage capacity of inspection
data equivalent to more than 475,000
thickness readings, or 20,000waveforms
in various file formats, while the MicroSD
card slot provides additional storage.
The GageView interface program allows
for data transfer with a standard USB
cable.

Digital inline profile projector
KJM GmbH, Germany, has developed
Geokon, a high-precision 2D profile
inline measurement system for all types
of profiled products during production.
Four sensors acquire four images of
the object. The data is then analysed
on the system computer by image
processing software. Rectangular
profiles as well as complex profiles can
be measured.
The profile types can be entered as
CAD-data in the DXF file format using
the “Teach-In” program. This allows
new products to be defined very simply.
The technical drawing must be saved in
DXF-format and entered into the “Teach-
In” program.
The measurement parameters are
then defined, as in CAD programs,
by entering dimensions, creating a
name (eg R15), defining tolerance
or intervention levels and saving the
parameters. For a new measurement,
only the article to be measured must be
selected.
The results are displayed numerically
as well as graphically. An exclusively
numerical display of important
dimensions in large numbers can be
selected. Values outside of tolerance
are highlighted in colour. Measurement
results are saved, printed or transferred
to computer-aided production data
acquisition PDA or QM-systems,
according to customer requirements.
