USM 36 Ultrasound Portable Flaw Detectors
USM 36 Ultrasound Portable Flaw Detectors
The Krautkramer USM 36 is the latest development in GE’s USM range of flaw detectors.
It combines the 21st century operating platform with the reliable and robust hardware of GE’s well-established Krautkramer portable flaw detection instruments.
It incorporates a range of innovative features to ensure that this new instrument is adopted as the everyday workhorse of flaw detectors by NDT inspectors globally.
Largest Viewable A-Scan Display in its Class
An important improvement in the Krautkramer 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, with tired eyes at the end of a long working day.
Simple and Efficient Operation
The Krautkramer 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; 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 commonality of interface also ensures a rapid learning curve for technicians familiar with the USM Go instruments.
Flexible Data Reporting and Storage
As well as easy-to-interpret the crispy A-scans, data reporting on the Krautkramer USM 36 can also include screen shots and A-scan videos, where A-scans can be recorded for subsequent analysis or to provide proof of inspection. All data is stored on a removable SD-card and reports can be in jpeg or BMP format.
Connectivity is a major feature of the Krautkramer 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 be shown on an external monitor or on a projector screen for training purposes.
Can be Used in the Harshest of Environments
The Krautkramer USM 36 is fully protected against dust and water ingress to IP66 and can be 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 new flaw detector weighs just 2.2 kg and is battery- or mains operated. Its Li-ion battery has an operating life of more than 13 hours, with an integrated battery charger for those longer shifts.
Available in Three Versions
The versatile instrument is offered in three versions to meet the 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 GE’s patented trueDGS probe technology, which offers unrivalled accuracy in sizing of flaws using the DGS method, as well the patented Phantom Echo Detection technology.
Weld Inspection in the Power Generation and Petrochemical Industries
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 in various 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
- GE’s patented color coded display of legs for angle beam inspection
Precise Thickness Measurement in the Automobile Industry
The Krautkramer USM 36 provides precise thickness measurement, as the sound path differences are measured very accurately at the peaks of an echo sequence.
Corrosion Measurement in the Power Generation and Petrochemical Industries
Corrosion measurement can be carried out using dual element probes, where the screen displays both the thickness 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 long work pieces to ensure accurate detection of flaws but not Ghost Echoes.
Inspection of Special Materials
The powerful square wave pulsar which is an available option for the Krautkramer USM 36 provides excellent penetration of difficult materials, such as those sometimes used in the aerospace and automobile industries.
