Intelligent Ultrasonic Flaw Detector

Performance characters:
Operation interface: using of all Chinese man-machine dialogue method, functional display window and menu operation make it modern and practical.
Operation menu: Turn on the detector into aircraft model menu and select the model, then automatically enter the parts menu and confirm the part need to be detected, and automatically show the flaw detection method schematic diagram of the part and with inspection specification, then the instrument automatically enter the inspection process, and start inspecting.
Flaw detection process: Set the detection process of aircraft structural testing parts in the instruments in the form of software. When do flaw detection, the instrument automatically call out the process to use.
Detection intelligence: Turn on the detector, the instrument prompts the operator to confirm the aircraft models, flaw detection parts, probe models, scanning methods etc, and the instrument can automatically call up the corresponding testing process, the operator only need to guide the instrument into the flaw detection process according to the program, do not have to adjust the parameters of the instrument according to the flaw detection process, so the instrument has strong flaw detection intelligence.
Spectrum analysis: Analyze the echo spectrum distribution with FFT, read out the center frequency and bandwidth of the reflected wave, and compare the frequency spectrum to analyze the probe characteristics and defect properties.
Curve compensation: Measure the echo size based on the set or measured amplitude curve distance.
RF expansion: echo within the gate expand in the form of RF display.
System calibration: Calibrate measure and set the parameters such as sound velocity, incident zero point, refraction angle, probes leading edge, distance volatility curve, and so on.
Peak envelope: retain the echo peak motion trajectory.
Average noise reduction: use digital signal processing technology to stack echo in multiple times and reduce the random noise.
Detection mode: positive half-wave, negative half-wave, full-wave detection and RF echo.
Storage capacity: can store and playback more than 1000 data waveform images.
Data storage: with testing process and project documents and crack reporting three types of data storage and playback function.
EL display: use electroluminescent flat panel display to meet the wide temperature, anti-vibration, wide viewing angle, high brightness and high contrast. It can response fast and display waveform, menu or positioning values in real time clearly and stably. It has good visibility used in and out of the field, and needs no backlight.
Data communication: The standard LPT two-way communication interface connected with computer to transfer waveform, graphics and files, achieving the computer data management of flaw result
Portable and practical: With AC and DC integrated power, the instrument can work for more than 6 hours in the battery power supply. And with small size, light weight, low power consumption and lightweight, it’s suitable for field testing.
