Low Frequency Magnetic Flaw Detector TCLF

Low Frequency Magnetic Flaw Detector TCLF

Product catalog summary

Brief Introduction:
The TCLF series magnetic flaw detectors combine the advantages of inspection using both direct and alternating currents. By utilizing low-frequency electric current, the flaw-detecting depth is enhanced, allowing for slight vibration of magnetic powder, which aids in forming magnetic marks. These detectors are widely used in industries such as shipbuilding, aerospace, steel manufacturing, foundries, welding, and vehicle inspection.

Features:

Completely portable for single-handed operation.
Reliable detection of defects in ferrous metals.
Enhanced penetration depth due to the magnetic field.
Capable of detecting artificial cracks (0.1×2×30mm) at a depth of 6mm.
Efficient floatation of magnetic particles for easy absorption on defects.
No demagnetization required post-detection.
Direct detection without surface processing.

Low Frequency Magnetic Flaw Detector TCLF-1

ISO 9001 LOW-FREQUENCY MAGNETIC FLAW DETECTOR TCLF D2 Brief Introduction Features Technical Specifi cation œ TCLF series summarized the merits of inspection by direct and alternating currents. The flaw-detecting depth is improved by adopting low-frequency electric current, and this pulsating current can enable the slight vibration of the magnetic powder ranks, which facilitates the permutation of the magnetic powder and forms the magnetic mark. it is widely used in the shipyard, aerospace, steel, mill, foundry, weldment or vehicle inspection.
