Digital Ultrasonic Flaw Detector MFD500

Description

MFD500 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 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: 100O, 200O, 400O selectable 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
