In modern manufacturing, especially in the automotive industry, the quality of engine connecting rods is crucial. Eddy current sorting machine, as an efficient inspection tool, plays an important role...
Testing Standard：GB/T 11260-2008 round steel eddy current testing method, GB/T 7735-2004 steel tube eddy
Current testing method
Longitudinal artificial injury:0.10（depth）×0.10（width）×20mm（length）
Tube end conditions:
deburring at both ends, cross-sectional deformation equal to less than the diameter tolerance
Straightness tolerance: tangential direction up to 1.5mm/m and not exceeding the total length of the workpiece
Diameter tolerance and ovality: reference DIN standard
(1)The eddy current flaw detector can accurately, reliably and stably record, alarm and mark the defects of the finished steel pipe.
(2)Detection speed:<60m/min
(3)Detection of end -end tail dead zone:
50mm signal to noise ratio: ≥ 10dB
Sample miss rate: 0%
Sample stick false positive rate: ≤2%
Stability: ≤1dB after 2 hours
Marking accuracy: ±30mm
Poor circumferential sensitivity: ≤1dB
(4)100% coverage detection, the instrument sets the upper and lower boundaries, exceeding or lower than the automatic alarm record;
(5)Operation mode: This portable eddy current tester for sale is fully automatic, with a complete electronic control system, testing equipment, and auxiliary control
Precision positioning and drive mechanism technology in tube rod inspection;
Adopting the rotation of the probe and straight forward of the tube rod, the speed is fast, the noise is small, reliable, and the sensitivity is high;
Multi-channel noise suppression technology;
Detecting steel rods of different diameters without changing the probe, can continuously and accurately adjust the gap between the steel rod and the eddy current probe;
The signal adopts high-speed DSP signal processing mode, and each channel signal is processed independently, and the transmitted signal-to-noise ratio is high;
Wireless transmission technology, no sparks:
Has a high service life and a small longitude detection blind zone;
Do not replace the probe rotation detection technology;
The equipment can operate stably all year-round.
