Ultrasonic Product Digital Ultrasonic Flaw Detector Ew-900 for Nondestructive Testing

Ultrasonic product Digital ultrasonic flaw detector EW-900 

for Nondestructive testing

The design of developed high precision EW-900 digital ultrasonic flaw detector considering the 
users' needs and habits, to refer to a wide range of experience in design and application of many 
ultrasonic testing equipment, using the most advanced hardware, software, acoustics, human 
engineering technology, the practical advantages in both the functional index and convenience are ahead of similar products.
Use not only convenient operation, but also rich, practical auxiliary functions also help users 
greatly improve the work efficiency, so that the original heavy inspection work becomes easy. And itsunique broadband characteristics make both low-frequency and high-frequency probe can be 
matched, all kinds of detection needs are met.

- 400MHz real time hardware sampling rate, echo pulse is more realistic and reliable.
- broadband low noise amplifier circuit, which can be matched with low frequency and high frequency probe
- good shielding design, strong anti-interference ability
- 5.7 "color LCD screen of high resolution
- DAC curve generation, storage, call function:
Production simple: one by one point, automatic generation of assessment, quantitative line, DAC line, sentenced to waste line four 

curves
Easy to edit: can independently modify the sampling points, the curve spacing can be adjusted (to 
adapt to a variety of standards)
- AVG curve generation, storage, call function:
Simple production: > > 3N area can be automatically generated by sampling a point, the 3N area is 
sampled into a curve, and the utility of the curve is ensured.
Easy to use: self adjustable equivalent curve, automatic calculation of defect equivalent value
-radio frequency display function: the true display of the original waveform, convenient and detailed 
analysis of the echo 

characteristics, auxiliary defects qualitative analysis
- surface modification function: automatic correction of arc detection results
- peak memory function: to help record the highest echo
- envelope function: record the change of echo
- Automatic Test echo frequency spectrum function: can be used to test the spectrum of probe
- gain automatic adjustment function: automatic gain height can adjust, achieve fast adjustment echo height
-the function of the detection of the welding seam: the intuitive graphics display, the defect position 
is clear, the picture can be stored in the inspection report, and it is very convenient to play back 
and print.
- intelligent device calibration procedures: including the rapid calibration of the material speed of 
sound, automatic measurement of the probe delay, automatic calibration of the probe K value, more easy to calibrate the probe
- fast channel setting function: 30 fast track can be set up and store 30 sets of testing parameters, 
storage, call the operation is quick 

and easy
- report automatic generation of function: the system according to the testing parameters and 
detection data to generate a test report, 

the report contains detailed testing parameters, waveform images and detailed echo data, and can 
be directly connected to the printer's report, or the computer is connected to the computer
-continuous storage and playback functions: recording and testing process of the screen echo 
waveform and data dynamic 

changes, so that the data record is more detailed, similar camera function menu settings, easy to 
operate, and the storage file can be stored directly on the U disk storage device
- waveform display area zoom function: waveform display area can be reduced, the use of the screen more fully
- gate area of the amplification function: the gate area is enlarged to the entire waveform display
 area to display, easy to observethe waveform details
