Function & application

The instrument can be widely used in locating and sizing hidden cracks, voids, disbands and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines and structural components.

Working Principle

When presence of a defect in a workpiece with homogenous material, due to the defects, it will inform the interface among different mediums between the defect and workpiece. As the acoustic resistance is different at the interface, after the pulsing ultrasonic wave met the interface, it will produce reflection. The reflected energy will be received by the probe. Then it will show a reflection waveform in a certain abscissa position in the display screen which is the defect depth in the workpiece. The height and shape of reflecting wave would be different caused by the different defects which reflect the defect’s character.

Working Conditions

Operating Temperature: -10℃ to 50℃;

Storage Temperature:-30℃ to 50℃

Relative Humidity: (20 ~ 95)% RH

The surrounding environment should avoid of vibrating, strong magentic field, corrosive medium and heavy dust.

Instrument Features

Gate Alarm

Gate position, gate width and gate height can be adjustable at will. The B gate can chose to set wave-getting alarm OR wave-losing alarm. The beep in gate and LED light can be alarmed or closed (the LED light alarm is very effective under the noise environment). The capture mark function can show the captured echo characteristics in the gate.

Data Storage

The instrument is built with mass storage. The data and files will not be lost because of instrument power breakdown. The storage contents included channel parameters, waveform pictures and video files. It supports 100 groups of flaw detecting parameters channels. It can preset well for the combination parameters of various types of probes and instruments. It can add locks to each channel and change the channel name as well as set testing standards for each industry freely. It can save 20000 pictures of detecting echo signals and parameters. It can realize communication with PC.

Video Function

The instrument supports for saving the inspection process as video file and save it to the internal storage card. Video file can be replayed through the instrument. The instrument can support maximum 100 hours of video files. Playback the inspection process video makes great convenience for learning detecting but also saved for the future analysis to the inspecting process.

REAL-TIME CLOCK

Record and save the tracking record of detecting date and time in real time.

Communication

High speed USB2.00TG communication interface with USB cable connecting instrument and computer, it can realize data file transfer and work for USBHost mode to operate the external connecting U disk.

Battery Module

The large capacity lithium battery module is easy to be assembled and disassembled. It can be charged independently but also charged by inserting wire. Its continuously working time is more than 10 hours.

Performance Self-checking

The instrument can automatically test the instrument probe’s combined performance indicators (including horizontal linearity error, vertical linearity error, resolution, dynamic range, sensitivity range, sensitivity margin) and can generate the testing report.

Operating Method and Attentions

Simple Operation Way:

1. Connect the probe to instrument with probe cable

2. Power on the instrument

3. Choose the channel and clear the present channel

4. Calibration the probe

Straight Probe: P-Delay

Angle Probe: P-Delay, X-value, Angle

5. Make AVG curve (straight probe), DAC curve (angle probe)

6. Choose the function setting

7. Detecting flaw in the workpiece

8. Record the flaws

9. Power off the instrument after operation
