GE Inspection Technologies USN 60

GE Inspection Technologies USN 60 is designed for outdoor use with two independent gates to monitor amplitude and soundpath distance for both flaw detection and thickness measurement applications. It features pulse echo, dual, and thru-transmission test modes as well as measurement modes for zero-to-first and multi-echo with selectable flank or peak detection. This flaw detector also calculates weld ratings according to AWS specification D1.1 (formula D=A-B-C).

GE Inspection Technologies USN 60 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 a powerful portable ultrasonic inspection tool.

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ﾒ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 for easy weld inspection

• Color Leg allows easy identification of leg and skip distances for weld inspection
  • GRID mode dynamically changes bands of display backgroundcolors for each leg.
  • A-SCAN mode dynamically changes the color for each leg of the ﾓliveﾔ A-Scan
• Weld Rating Calculation simplifies the rating of weld indications according to AWS Specification D1.1. (Formula D = A ﾖ B ﾖ C).
• Trigonometric flaw location function with curvature correction automatically calculates depth, surface distance, and sound path to flaw along with the leg of the inspection when using angle beam probes. All TOF measurements can be displayed in mm, inches or µs.
• SmartView function along with variable persistence freeze modes displays the most important information (relevant shot) for a test.
• Real time (single shot) analog and TTL outputs handle a wide range of automated systems applications.
• Choose from Four Freeze Modes: ALL, Peak Std, Compare or Envelope for optimum waveform evaluation and comparison.
• Three Variable Persistence Modes are selectable in Freeze Envelope to visually assist flaw detection & evaluation for scanning and moving part inspections.
• Compare frozen reference wave-forms to live A-Scans in different colors to easily interpret test results.

Documentation and recording

• Store & preview a minimum of 200 user-named data sets with A-Scans for quick recall and instrument setup.
• UltraDOC 4 software program for bi-directional communication with a PC for easy storage of data sets with A-scan and documentation of test results.
• UltraMATEﾙ software program simplifies the transfer, storage, analysis, and documentation of thickness data.
• Reports with A-Scans are output directly to a variety of printers.
