Based on ultrasonic principle, digital ultrasonic flaw detector MFD550B can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. With full digital 640X480 TFT LCD display, it show the defect clearly under the dim light and strong sunlight environment. 0-9999mm measuring range can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium ion battery module，it can work more than 10 hours continuously. Full English master-slave menu, emphasizing on user experience, collecting shortcut keys, digital shuttle rotary wheel, cross menu three operating ways inone body, customers with different habits can operate it freely. With comprehensive performance self-checking function, it can automatically generate test reports and support for many languages. With high cost performance, it is the smart choice for the practical economic model of ultrasonic testingequipment.
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.
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.
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.
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.
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.
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 pieces of video files. The video totally time is not less than 10 hours. Playback the inspection process video makes great convenience for learning detecting but also saved for the future analysis to the inspecting process.
Record and save the tracking record of detecting date and time in real time.
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.
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.
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
1. During pressing key operation, please not be too hard. Please not use the hands with much oil or mud for operating the instrument keypad to avoid affecting the keypad working life.
2. Please clear the instrument cover after operation
3. Please keep the instrument in a dry and clean place
4. Please avoid oil, water or other liquids into the instrument and clean the instrument surface regularly.
5. Make sure not twist or press the probe cable, communication cable and power cable. Please grasp the plug root during inserting or pulling the cable. Don’t grasp the cable for pulling or inserting.
6.Please make sure the standard battery for working power adapter for charging. Otherwise, the instrument would be damaged easily.
