YUT2820 Portable, digital ultrasonic flaw detector

Functions

1. Wave peak memory: real time envelopes show the highest wave of the flaws and record the maximum value of the flaws, it is helpful to locate the flaws precisely and scan the work piece quickly. With the help of envelope waveform, the quality of the flaws can be determined.

2. Automatic gain: automatically adjust the gain to the preset amplitude height.

3. Alarming function: afferent echo/echo loss alarming.

4. Real-time clock: automatically record and store the date and time of waveforms.

5. Display freezing: catch waveforms and sound path data at any moment, and the gate can be moved after freezing to measure the echo parameters.

6. Flaw positioning: real-time display sound path S, horizontal X, depth Y, and wave height H.

7. Digital Reject: 0-80%, increase by 1%, unaffecting the linearity and gain.

8. Wave height reading: three display modes, namely relative wave height, dB difference relative to the gate, and dB difference relative to DAC curve.

9. Data communication: communicate with the computer through RS232 port to transmit waveforms and data so as to manage the result of detection on the computer, and generate the flaw detection reports, as well as print out reports.

10. 2 independent measurement gates, monitoring the echo amplitude and the sound path distance.

11. When using transverse wave to detect flaws, the depths of the second and third waves are automatically calculated according to the slab thickness.

12. Perfect DAC/AVG curve functions, the curves change along with the changes of the gain, sound path, and displacement. It can be straight line or curve.

13. True color TFT LCD whose brightness is adjustable, with many color schemes to choose freely.

14. DAC Curvilinear Distance Compensation: the device is designed for distance compensation. When the resolving power in the near field is not influenced, only the remote signal will be compensated for its sensitivity so as to improve the testing range of the device significantly.

15. Φ Value calculation: the device can calculate the equivalent of the flaw according to the flaw wave height automatically.
