ECS-308L eddy current flaw detector

ECS-308L eddy current flaw detector designed for round tubes, flat tubes online, offline detection, copper speed real-time match; not affect production.

detection principle

    The system does not require any coupling agent between the probe and the workpiece non-contact measurement. Eddy current tester produces alternating current by checking the coil induces eddy currents in the workpiece surface. Surface of the magnetic field generated by eddy current test coil in turn affect the electrical impedance. When the surface defects, damage to the original vortex field, causing the coil impedance change detection. Instrument by measuring changes in impedance of the probe signal processing to achieve automatic detection of defects.

The main performance instrument

1. test speed: 0.1 m / min to 500 m / min

2. Frequency range: 100Hz ~ 1MHz

3. Gain 0 ~ 60dB, adjust the volume 1dB / file

4. speed matching bandpass filter or

5. all-digital computer parameter adjustment

6. Real-time impedance plane display

7. provides Xt, Yt, Vt three time-based scan for real-time display mode selection

8. defects automatically records the location

9. Dynamic length marking function (high-speed testing not required)

10. head and tail cut function

11. high-precision real-time, delay alarm output

12. pieces of phase / amplitude alarm technology;

13. automatic date and time display

14. eddy current testing signal playback, analysis, archiving, printing
