KRAUTKRÄMERUSM 36

Universal portable ultrasonicflaw detector

The universal portable ultrasonic flaw detector from Waygate Technologies,
combining ergonomic and robust design and the biggest display screen of its
class with state-of-the-art UT performance.

Krautkrämer USM 36

A proven reliable and robust
ultrasonic flaw detector performer
The Krautkrämer combines the 21st century
operating platform with the reliable androbust hardware of Waygate Technologies’
well-established Krautkrämer portable flaw

detection instruments. It incorporates a range
of innovative features to ensure that this new
instrument is adopted as the everyday workhorseof flaw detectors by NDT inspectors globally.

1Largest Viewable A-Scan Display
in its Class• An important improvement in the Krautkrämer USM 36 is
its large 7 inch screen, with an 800x480 pixel resolution.
The entire area is available to display crispy A-scans,making it the best in its class. Signals can be easily viewed
and accurately interpreted, even in bright sunlight, withtired eyes at the end of a long working day.

2Simple and Efficient Operation• The Krautkrämer USM 36 uses the familiar rotary knobs
of previous models but the function keys have now
been minimized into a simple, intuitive 6-key keyboard,
allowing simple and efficient operation

3
Flexible Data Reporting and Storage• Inspection set-up is also easy. Not only for technicians who
have used USM Go or USM Go+ for previous inspections, as
set-up data is transferable directly from these instruments,
which share the same user interface. This commonalityof interface also ensures a rapid learning curve for technicians familiar with the USM Go instruments.

• As well as easy-to-interpret the crispy A-scans, datareporting on the Krautkrämer USM 36 can also include
screen shots and A-scan videos, where A-scans canbe recorded for subsequent analysis or to provide proofof inspection. All data is stored on a removable SD-cardand reports can be in jpeg or BMP format.

Applications
The Krautkrämer USM 36 has been developed forday-to-day use throughout the industrial spectrum,from weld inspection and corrosion measurement in
the power generation and petrochemical industries,
to castings and forgings inspection and thickness
measurement in the automotive, metals and aerospace sectors to the inspection of special materials.

Comprehensive Connectivity• Connectivity is a major feature of the Krautkrämer USM 36.
Data can be stored on removable SD-card or USB memory
stick, either for record purposes or to allow data sharing.
A VGA connection allows the instrument’s display to beshown on an external monitor or on a projector screen for
training purposes.

Intuitive tools facilitate analysis and the use of color on
the ultra-bright, 7 inch screen allows significant display
benefits during weld inspection:• Monitor gates and curves are displayed invarious colors• Messages and alarms are displayed in red• A-scans can be displayed in different colors
to assist comparison• Color display of all parameters involved in flaw
location, including sound path, surface distance,
depth position and leg number• Waygate Technologies’ patented color coded
display of legs for angle beam inspection

5
Can be Used in the Harshest ofEnvironments•

The Krautkrämer USM 36 is fully protectedagainst dust and water ingress to IP66 and canbe operated in ambient temperatures from-10°C to +55°C. It can be used in sandy deserts,frozen wastes and in the humid tropics.

•The Krautkrämer USM 36 flaw detector weighs
just 2.2 kg and is battery- or mains- operated.
Its Li-ion battery has an operating life of morethan 13 hours, with an integrated battery
charger for those longer shifts.

6
Available in Three Versions• The versatile instrument is offered in three versions to meetthe most standard inspection codes. The most advanced
version can operate in DAC, AWS and DGS modes,
features a powerful square wave pulser for excellent
material penetration and can accommodate Waygate
Technologies patented trueDGS probe technology, which
offers unrivalled accuracy in sizing of flaws using the DGS
method, as well the patented Phantom Echo Detection
technology.

Precise Thickness
Measurementin the AutomobileIndustry
The Krautkrämer
USM 36 provides
precise thickness
measurement, as thesound path differences
are measured very
accurately at the peaksof an echo sequence.
Corrosion Measurement in the Power Generationand Petrochemical Industries
Corrosion measurement can be carried out using dual
element probes, where the screen displays both thethickness measurement and the A-scan, ensuring maximum reliability. A minimum capture mode provides
the thinnest measured reading at the end of a continuous scan. An auto-freeze function, which minimizes
the probe’s surface contact time, is used for measuring
structures and components with hot surfaces.
Inspection of Forgings
The instrument’s Phantom Echo Detection technology
is used in the inspection of fine grained and longwork pieces to ensure accurate detection of flaws
but not Ghost Echoes.
Inspection of Special Materials
The powerful square wave pulser which is an available
option for the Krautkrämer USM 36 provides excellent
penetration of difficult materials, such as those sometimes used in the aerospace and automobile industries.
