Detail Digital Ultrasonic Flaw Detectors

Testing Instrument

Digital ultrasonic flaw detectors
Ultrasonic Flaw Detector is a portable industrial non-destructive testing instrument that can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) of workpieces easily, quickly, without damage. Used in electric power, petrochemical, boiler and pressure vessel, steel structure, military, aerospace, railway transportation, automobile, machinery and other fields.
Ultrasonic flaw detection can potentially be applied to any standard engineering material to find hidden cracks, voids, porosity, inclusion, and similar discontinuities. While most tests involve steel and other structural metals, flaw detectors can also be used on plastics, composites, fiberglass, and ceramics. Some common applications include:

Weld inspection -- by far the most important market for ultrasonic flaw detection

Primary metals -- beams, billets, bars, ingots, forgings, tubular stock

Infrastructure -- bridge beams, bridge pins, railroad rails, metal structures

Petrochemical -- pipelines, tanks, support structures

In-service testing -- railroad wheels and axles, aircraft landing gears and engine mounts, crane booms, drive shafts, tanks and pressure vessels, bolt testing

Manufacturing -- spot welds, braze joints, castings, bond testing

Composites -- aerospace parts, wind turbines, automotive composites, marine fiberglass
1. Full screen display function: make the echo display area cover the whole screen, bringing maximum visual feeling to the work.

2. Mass storage: can store up to 1000 data sets, including waveforms, curves, parameters, etc. (including 1000 channels in the traditional sense)

3. Measuring point: peak value or front edge of echo in valve

4. Echo-echo thickness measurement: Zero calibration is omitted, and the net thickness of the substrate can be directly measured through the coating.

5. Peak memory: real-time envelope displays the highest wave of the defect and records the maximum value of the defect, which is helpful for accurate location and fast scanning of the defect, and can also help to identify the defect by means of envelope waveform.

6. Automatic gain: automatically adjust the gain to the set amplitude height

7. Alarm function: incoming/lost wave alarm

8. Solid waveform display: increase visual contrast of waveform, fast scanning is not missing

9. Real-time clock: automatically recording the date and time of the stored waveform

10. Display freezing: capture waveform and acoustic range data at any time, and move the valve to measure echo parameters after freezing.

11. Defect location: real-time display of sound path S, level X, depth Y and wave height H.

12. Defect quantification: real-time display of dB difference value and SL quantification value

13. Digital suppression: 0-80%, increasing by 1%, without affecting linearity and gain

14. valves a and b: two independent measuring valves to monitor echo, amplitude and acoustic distance

15. DAC, AVG curve function, curve changes with the change of gain, sound path and displacement

16. Distance compensation: Real-time compensation of flaw detection echo according to time-varying gain method to avoid missing small defects
18. Working languages: Chinese and English operating interfaces

19. Data communication: communicate with the computer through RS232 interface to transmit waveforms and data, so as to realize the management of deep injury results, the generation and printout of flaw detection reports on the computer.
