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 YUT-2620
| Full Screen Display Function | The echo display area covers the entire screen, the operator will have the maximal view. |
| Bulk Storage | Up to 1000 data sets can be stored, including waveforms, curves and parameters etc. (including the traditional 1000 channels). |
| Measuring Point | Peak Mode or Front Mode |
| Echo-echo Mode | No need of zero calibration , the net thickness of the base material can be directly measured through the coating. |
| Wave Crest Memory | The real-time envelope can display the highest wave of the flaw and record the maximum value of the flaw to help the exact positioning and fast testing of the flas as well as the qualitative analysis by the envelope waveform. |
| Automatic Gain | Automatically adjust the gain to the pre-set amplitude height. |
| Warning Function | Afferent echo /lost wave alarm. |
| Solid Waveform | Can add the waveform visual contrast and omission will hardly happen during the fast testing. |
| Real-time Clock | Automatically record the date and time of the stored waveform. |
| Display Freezing | Catching the waveform and the sound path data at any moment and removing the gate after freezing to measure the echo wave parameters. |
| Flaw Positioning | Real -time display the sound path S, horizontal X, depth Y, and wave height H. |
| Flaw Quantify | Real-time display the dB difference & SL quantitative values. |
| Digital Inhibition | 0-80%, increasing by 1%, not affecting the linearity and gain. |
| Independent Measurement Shutters | 2 independent measurement gates, monitoring the echo amplitude and the sound path distance. |
| DAC、AVG Curve | Perfect DAC、AVG curve functions, enable the curves to change along with the changes of the gain, sound path, and displacement. |
| 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. |
| Φ Value Calculation | This function is used for calculating the flaw quivalent. |
| Language | English and Chinese |
| Data Communication | Communicating with the computer through the RS232 interface to transfer the waveform and data so as to manage the results of the flaw on the computer, generate the flaw testing reports and print them out. |
