Krautkramer USN 60

The USN 60 combines the powerful advantages of digital design with the detailed dynamic echo information that was previosusly possible only with an analog display.

The USN 60 flaw detector series has been optimized for use in direct sunlight and operation at extreme temperatures. These new characteristics make the instruments ideally suited for outdoor use with its increased long battery operation time.

Depending on the applications challenges, you have the choice between the USN 60 and the USN 60L version.

Outstanding ultrasonic performance: The combination of the rugged USN durability, 11 hours of battery operation, fast rotary knob operation, outstanding ultrasonic performance, and the "square wave pulser" form powerful portable ultrasonic inspection tool.
Optimized outdoor use design: The USN 60 / USN60L flaw detectors are especially designed to be used outdoors:

* 1 mm to 28 m (0.040” to 1100”) range (in steel) covers thin to lengthy acoustically clean materials.
* dB REF key evaluates subsequent echoes gain value and amplitude against the highest echo in Gate A (reference echo) when activated.
* IF (Interface) Gate Option for automatic start of the display, Gate A, Gate B, and / or DAC / TCG for immersion testing applications.
* VGA Output Option provides an easy way to connect
to a PC monitor or PC projector for viewing by large audiences or training purposes.
* RF Output Option outputs the raw RF waveform via a standard Lemo connector for further analysis.
* BEA (Backwall Echo Attenuator) Option allows independent gain control of the region under Gate B for backwall echo monitoring.
19" Rack Mount Model.

Wide range of applications
* A 6 kHz pulse repetition frequency, real-time analog and TTL outputs makes the USN 60 flaw detectors series ideal for a wide range of automated systems testing applications.

The exclusive SmartView feature displays even the shortest echoes for critical scanning and rotating part inspections. The quality, durability, dependability and ease of use that you have come to expect of Krautkramer’s popular USN Series of instruments remains. From rugged field inspections to high resolution thin measurements, long acoustically clean materials, and immersion systems, the USN 60 flaw detector family extends the range of applications that a portable instrument can perform.

Furthermore the selectable 450V Square Wave Pulser satisfies a wide range of tough-to penetrate applications, such as difficult to penetrate metallic applications and especially non-metals inspection like composite materials.

Tools of easy weld inspection
* Color Leg allows easy identification of leg and skip distances for weld inspection.
* GRID mode dynamically changes bands of display background colors for each leg.
* A-SCAN mode dynamically changes the color for each leg of the "live" A-Scan.

Tools for easy defect sizing
* 40 dB dynamic DAC/TCG Option corrects for distance/ amplitude variations from material loss and beam spread with ability to edit or insert recorded echoes individually. Up to four DAC curves can be drawn on the screen at one time to show +/- dB curves in addition to the originally recorded DAC curve.
* DGS (Distance Gain Size) Option displays a curve for a particular equivalent reflector size. The ERS (Equivalent reflector size) function automatically calculates the corresponding equivalent reflector diameter in mm or inches for any echo in the measurement gate.
