Portable Ultrasonic Flaw Detector SV-MFD**0

FEATURES:

SV-MFD**0 Portable Ultrasonic Flaw Detector with hi-resolution color TFT LCD display.

The background color and the wave color can be selectable according to the environment.

LCD brightness can be manually set. Continue working over 8 hours with high performance

lithium-ion battery module (with large capacity lithium-ion battery option), easy to be

dismantled and the battery module can be charged independently offline. It is light

and portable, easily to be taken by one hand; easy operation; superior reliability

makes it long life.

RANGE

0~ ***9mm (at steel velocity); range selectable in fixed steps or continuously variable.

PULSER:

1. Spike excitation with low, middle and high choices of the pulse energy. 

2. Pulse Repetition Rate: manually adjustable from *0 to ***0 Hz.

3. Pulse width: Adjustable in a certain range to match different probes.

4. Damping: **0Ω, **0Ω, **0Ω selectable to meet different resolution and sensitivity need.

5. Probe work mode: Single element, dual element and through transmission;

RECEIVER:

Real-time sampling at **0MHz high speed enough to record the defect information.

Rectification: Positive half wave, negative halfwave, full wave, and RF

DB Step: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gain mode

ALARM

Alarm with sound and light,.

MERMORY:

Total **0 configuration channels store all instrument operating parameters plus DAC/AVG curve;

stored configuration data can be easily previewed and recalled for quick, repeatable instrument setup.

Total ***0 datasets store all instrument operating parameters plus-scan. All the configuration channels

and datasets can be transferred to PC via USB port.

FUNCTIONS 

1. Peak Hold:

Automatically searching the peak wave inside the gate and hold it on the display.

Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter.

2. Continuous Record: Record the display continuously and save it to the memory inside the instrument.

3. Defect Localization: Localize the defect position, including the distance, the depth and

its plane projection distance.

4. Defect Sizing: calculate the defect size

5. Defect Evaluation: Evaluate the defect by echo envelope.

6. DAC: Distance Amplitude Correction

7. AVG: Distance Gain Size curve function

8. Crack measure: Measure and calculate the crack depth

9. B-SCAN: Display the cross-section of the test block.

REAL-TIME CLOCK

Real time clock for tracking the time.
