Leading of acoustic emission equipment providers
Share：Physical acoustics Pocket UT is the latest company to launch the world's first based on PDA handheld ultrasound A/B/C/TOFD scanning detection system.
It combines modern digital ultrasonic technology, ultrasonic image processing technology and PDA technology at a suit.
Has the following main functions:
Compared with similar products of the main characteristics are as follows:
Palm type/pocket: all weighs less than 1 kg;
Easy to use: any working conditions, all can achieve single operation;
Touch screen operation: all operations including setting, parameter adjustment, display, record, and other functions can be done by screen operation, very convenient.
Itself a powerful signal/image processing functions, persistent data/record store image.
All Chinese interface, WINDOWS CE operating system
Standard USB interface to facilitate communication with computers
Traditional technology status quo of corrosion detection:
The most widely used corrosion testing still stays on the traditional method of ultrasonic thickness - that is, in a large area through the thickness on the points of through a limit to the change of thickness of the points on the overall corrosion condition.
Therefore, the conventional ultrasonic detection method has great limitations.
1, cannot form effective graphical display/record.
2, not an area of 100%.
3, not to grasp the overall corrosion conditions.
Detect personnel if you want to know quantity and thinning thickness thinning rate, it is hard to done by traditional methods.
Pocket UT inspection technology progress
1, for the first time that it is difficult to climb at the scene of bridge structure in C scan images and TOFD weld inspection is possible.
2, the traditional point-to-point ultrasonic testing to the area of detection.
3, the traditional manual point-to-point data to automatic, fast and testing data obtained in large quantities.
4, A scanner to the traditional A/B/C scanning of image detection.
5, broke through the traditional coupling agent request, must be used for detecting free of coupling agent.
6, broke through the traditional field instruments are difficult to communicate with computer communication, realize the use of USB interface and flash memory CARDS and computer communication and data sharing.
7, breakthrough the limitations of the traditional text test report and implement the detection images can be easily embedded Windows file with pictures and inspection report.
8, can easily realize the specific detection for annual inspection, review of permanent records and database testing.
The superiority of TOFD technique
(1) can accurately measure flaw size;
(2) can measure the size of the defects in thickness direction, it provides important data for fracture mechanics assessment;
(3) it is a kind of measuring accuracy is not affected by the only caused by rough surface specimen structure acoustic signal amplitude fluctuations of ultrasonic testing technology;
(4) for butt joint, TOFD can measure the size of the defects and defect from the depth of the surface;
(5) the use of the time difference of diffracted wave instead of amplitude to quantitative defect, defect detection rate is higher than A pulse type ultrasonic flaw detection.
