Product Description
Application
YUT series ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument that can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) of the workpiece conveniently, quickly, without damage, and accurately. Used in universities, electric power, petrochemical, boiler pressure vessels, steel structures, military industry, aerospace, railway transportation, automobiles, machinery and other fields.
Features of YUT2820
Full-screen display function
: The echo display area covers the entire screen, giving workers the greatest window experience.
Large-capacity memory:
can store up to 1000 data sets, including waveforms, curves, parameters, etc. (including 1000 channels in the traditional sense).
Measuring point:
the peak value or leading edge of the echo in the gate.
Echo-Echo Thickness Measurement
: Eliminates the need for zero point calibration, and can directly measure the net thickness of the substrate through the coating.
Wave crest memory:
The real-time envelope shows the highest wave of the defect. Recording the maximum value of defects is helpful for precise positioning and quick scanning of defects, and can also help qualitative defects with the help of envelope waveforms.
Automatic gain:
automatically adjust the gain to the set amplitude height.
Alarm function:
incoming wave/lost wave alarm.
Solid waveform display:
increase the visual contrast of the waveform, and it is not easy to miss the detection when scanning quickly.
Real-time clock:
Automatically record the date and time of the stored waveform.
Display freezing:
capture waveform and sound path data at any time, and move the gate to measure echo parameters after freezing.
Defect location:
real-time display of sound path S, level X, depth Y, wave height H.
Defect quantification:
real-time display of dB difference and SL quantitative value.
Digital suppression:
0-80%, in increments of 1%, without affecting linearity and gain.
Gates A and B:
2 independent measuring gates to monitor echo amplitude and sound path distance.
DAC curve:
perfect DAC curve function, the curve changes with the change of gain, sound path and displacement.
Variable emission pulse generator:
the pulse voltage is continuously adjustable from 50 to 400 volts, and the pulse width is continuously adjustable from 25 to 1000 nanoseconds (2800 and 2820).
Impedance matching:
33/50/100/500 ohms four gears adjustable.
Probe pulse width:
2-1000us continuously adjustable
Receiving filter:
1-4MHz, 0.5-15MHz adjustable in two levels.
The repetition frequency is adjustable in multiple levels:
avoid reverberation (phantom) signals when detecting large workpieces.
Working language:
Chinese and English two operation interfaces.
Data communication:
Through the RS232 interface and the computer, carry out the transmission of waveforms and data, realize the management of the detection results on the computer, the generation of the detection report, and the printout.
DAC, AVG curve:
perfect DAC, AVG (2620 and 2820 only) curve function, the curve changes with the change of gain, sound path, and displacement.
Distance compensation:
according to the time-varying gain method, real-time compensation for flaw detection echo to avoid missing small defects (2620 and 2820 only).
Φ value calculation:
automatically convert the defect echo height into the defect equivalent size (2620 and 2820 only).
