EUT-101C is a new product of Xx Company's high performance portable ultrasonic detector series for large-scale casting and forging structures of power plants and aircraft parts.




  • The instrument not only has the characteristics of high sensitivity, broadband, high resolution and high recovery rate. Various shortcuts and interfaces, as well as some new functions, such as B scan defect imaging, AB scan display, dynamic wave recording and playback for more than 3 hours, are used to generate standard atlas and remote diagnosis.
  • Independent software for instrument and key functions is designed for full-text prompts and help based on simple operation and understanding.

1. High emission pulse amplitude (Up 600V) and steep front rise time (tr 15ns) with very low effective output impedance (i.e., its load capacity is quite strong) can effectively stimulate high and low frequency probes of various wafer sizes to achieve high sensitivity and high resolution flaw detection.

2. It has the outstanding advantages of high input impedance, wide bandwidth (and both narrowband and broadband hardware), high signal-to-noise ratio and high fidelity transmission of echoes. It can be used not only for high sensitivity flaw detection of large forgings, but also for high resolution flaw detection of aircraft and automotive parts.

3. The "detection range" of 15m can be used to observe the axle end echo of 600 MW rotor conveniently.

4. Various measurement functions of gate make it possible to locate defects accurately; the function of "bottom wave attenuation" of gate d gives the concept of quantity to bottom wave monitoring; the "wave broadening" of gate b/c provides conditions for observing and analyzing echo details and judging the nature of defects.

5. The special playback function can record/store the dynamic waveform of flaw detection for a long time, which facilitates the archiving of flaw detection process, expert analysis and remote diagnosis.

6. The function of B-scan imaging and A/B-scan display on the same screen can not only realize defect visualization, but also store enough information for further data processing.

7. The stability and reliability of long-time work is the primary condition of large forging flaw detector. The instrument has strict control over temperature drift and long-time work drift.

8. High-performance transmitting system can effectively excite 10-20MHz high-frequency narrow pulse probe and obtain echo pulses with high amplitude and low ring period.

9.0.5~20MHz broadband receiving system can transmit high fidelity amplification of echo pulse from high frequency narrow pulse probe to digital circuit for further processing. In addition, 3~20Hz low frequency suppression of broadband band is beneficial to improving near-field resolution, which provides instrument guarantee for clear resolution of 0.4 flat bottom hole with 2.5mm near surface.

10. The high near/far field resolution obtained by using high frequency narrow pulse probe provides the instrumental condition, so it is especially suitable for the occasion where superficial or minor defects need to be found.

11. Equipped with crawler or mechanical scanner for automatic or semi-automatic inspection

12. The instrument adopts man-machine dialogue interface, which is clear and easy to understand, easy to operate, and helpful hotkey hints.

13. Random supporting computer software can image storage records, call back and play back, analyze or generate reports and print other functions.

14. Ultrasound testing parameters, graphics and files can be stored in 4 G memory of the instrument and called at any time.

15. Scanning data transmission can be carried out through network port or U port, desktop computer or similar instruments, and then computer management of the results of flaw detection process can be realized by matching computer imaging analysis software.

16. The rapid development of computer technology further improves the signal processing speed of the instrument. Compared with the original instrument, the detection frequency range is wider, the compatibility of the probe is better, the storage capacity is larger, the intelligent degree is higher, and the interface design is more reasonable.
