MFD650 Portable Ultrasonic Flaw Detector

KEY FEATURES

MFD650C 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~ 9999mm (at steel velocity); range selectable in fixed steps or continuously variable.

PULSER

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

Pulse Repetition Rate: manually adjustable from 10 to 1000 Hz.

Pulse width: Adjustable in a certain range to match different probes.
Damping: 200Ω, 300Ω, 400Ω, 500Ω, 600Ωselectable to meet different resolution and sensitivity need.
Probe work mode: Single element, dual element and through transmission;

RECEIVER
Real-time sampling at 160MHz 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,.

MEMORY  

Total 100 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 1000 datasets store all instrument operating parameters plus A-scan. All the configuration channels and datasets can be transferred to PC via USB port.

FUNCTIONS  

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.

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

Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.

Defect Sizing: calculate the defect size

Defect Evaluation: Evaluate the defect by echo envelope.

DAC: Distance Amplitude Correction

AVG: Distance Gain Size curve function

Crack measure: Measure and calculate the crack depth

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

REAL-TIME CLOCK

Real time clock for tracking the time.

COMMUNICATION

USB2.0 high-speed communication port
