Digital Ultrasonic Flaw Detector MFD**0 KEY FEATURES 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 Spike excitation with low, middle and high choices of the pulse energy. Pulse Repetition Rate: manually adjustable from *0 to ***0 Hz. Pulse width: Adjustable in a certain range to match different probes. Damping: **0Ω, **0Ω, **0Ω selectable to meet different resolution and sensitivity need. 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 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 SPECIFICATIONS Range: (0 ~ ***9) mm Bandwidth: (0.5 ~ *5) MHz Material Velocity: (***0 ~ ***9) m / s Dynamic Range: ≥ *2dB Vertical linear error: ≤ 3% Horizontal linear error: ≤ 0.2% Resolution:> *0dB (5P*4) Sensitivity Leavings: *0dB (flat-bottomed deep hole **0mmФ2) Rejection: (0 to *0)% Linear Noise level: ≤ *0% Power supply: DC 9V; lithium batteries work for 4 to 8 hours or more Ambient temperature: (**0 ~ *0) ℃ Relative Humidity: (*0 ~ *5)% RH Overall dimensions: **3 × **0 × *1 (mm)
