The MFD620C is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port.

The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.

Its waterproof, oil proof, dustproof function can achieve IP65 protection level. It is the necessary professional precision instrument for defect detection, quality control, on-line safety monitoring and life evaluation in fields of oil, chemical, metallurgy, shipbuilding, aviation, railways and so on.

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

Receiver

Sampling:10 digit AD Converter at the sampling speed of 160 MHz

Rectification:Positive Halfwave, Negative Halfwave, Fullwave and RF

Analog Bandwidth: 0.5MHz to 10MHz capability with selectable frequency ranges (automatically set by the instrument) to match probe for optimum performance.

Gain:0 dB to 110 dB adjustable in selectable steps 0.1 dB, 1.0dB, 2 dB, 6 dB, and locked.

Gates

Two fully independent gates offer a range of measurement options for signal height or distance using peak triggering.

The echo-to-echo mode allows accurate gate positioning for signals which are extremely close together.

Gate Start: Variable over entire displayed range

Gate Width: Variable from Gate Start to end of displayed range

Gate Height: Variable from 0 to 99% Full Screen Height

Alarms: Threshold positive/negative

Memory

Memory of 50 channel files to store calibration set-ups

Memory of 1000 wave files to store A-Scan patterns and instrument settings.

All the files can be stored, recalled and cleared.

Video Recorder

Screen scenes can be captured as movie files.  As long as 2 hours movie can be saved to the inside memory.  It can be re-played using the instrument or the PC software delivered with the instrument.

Video Recorder is useful in many situations, it is very convenient for those who want to analyze the probing activities later.

Real Time Clock

The instrument clock keeps running tracking the time.

Communication

High speed USB2.0 port. Two USB modes can be selected: U-DISK and U-BRIDGE. In U-DISK mode, the instrument acts as a USB flash disk when connected to PC. Configuration files, saved pictures and recorded movies can be copied to PC when possible. In U-BRIDGE mode, the instrument exchanges data with DataPro Software. The optional DataPro software helps manage and format stored inspection data for high-speed transfer to the PC. Data can be printed or easily copied and pasted into word processing files and spreadsheets for further reporting needs. New features include live screen capture mode and database tracking.

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
