Overview
FET-9NS Portable eddy current Flaw detector is a WENTAI brand equipment, suitable for online and offline flaw detection of metal pipes and bars, steel pipes, aluminum pipes and copper pipes. It uses an in-pass Probe to detect various defects on the inner wall of the tube, with high Sensitivity to detect axial defects such as longitudinal crazing, transverse defects, hidden and open crazing, and can reliably detect crazing and road injuries in the production process. The instrument adopts a fully digitalization design, supports multi-standard inspection procedures, and is convenient for users to switch product specifications. It also has input and output interfaces for automated integration.
Features
1. Portable design, easy to carry; 2. Adopt inside-through Probe, which can detect defects in the inner wall of the tube; 3. Have relatively independent test channels, drive combined Probe; 4. Detection channels for data collection at the same time, high Sensitivity detection of axial defects; 5. Full digitalization design, support the establishment of multiple standard inspection procedures or expert systems; 6. With input and output control interface, easy to work synchronously with device connection; 7. Frequency range (50Hz~ 12MHz), adapt to different product detection; 8. Continuous adjustable gain and phase, fine step; 9. Display modes (Impedance, Time Base) and alarm functions; 10. Operating language and online help.
Principle
The eddy current Flaw detector generates an eddy current in a metallic material by driving a combined Probe composed of absolute and differential coils. When the material has defects, the eddy current distribution changes, and the instrument detects these changes and collects signals. The detection signal is displayed on the screen in real time with the Impedance plan and the time base scan. Defects are identified by analyzing the signal amplitude, phase and other parameters, and sound and light alarms are output.
Applications
Metal Pipe Bar, Steel Pipe, Aluminum Pipe Copper Pipe
Steps
1. Connect Probe and power supply; 2. Select detection channel and Frequency; 3. Set gain, phase and alarm parameters; 4. Perform automatic equilibrate; 5. Start detection and observe signal display; 6. Process defects according to alarm output; 7. Use signal playback function to analyze defects; 8. Switch detection program to adapt to different specifications.
Notice
• Operating temperature range is 0~ 40 ℃ to avoid over-temperature use; • Storage Temperature range is -20~ 50 ℃ to prevent extreme environment; • Relative humidity does not exceed 85% to avoid moisture effects; • Power supply is lithium battery, it can be used for 6-8 hours at a time, pay attention to timely charging; • Use AC220 +/- 10V Operating voltage to ensure stable voltage; • Pay attention to the end and end signal cutting function settings when detecting; • Follow the Chinese help guide when operating to ensure correct use.
