DMD-24 High-speed eddy current flaw detector
Instrument Introduction：
Online high-speed or offline automatic detection suitable for metal tube materials (welded tube, seamless tube, ferromagnetic tube, non-ferromagnetic tube)。
Eddy current inspection for metal bars and wires。
DMD-24High-speed eddy current flaw detector integrates digital eddy current technology, microprocessor technology, and other technologies, with a detection speed of up to several thousand per second.6Rice, instruments with reliable, stable, and sensitive performance.DMD-24 High-speed eddy current flaw detectors offer a high detection sensitivity for defects in metal tubes, bars, wires, and filaments, such as surface cracks, hidden seams, pores, inclusions, and open cracks.
DMD-24High-speed eddy current flaw detector featuring computer-based Chinese (or English) menu-driven human-machine interaction, large-screen signal display, multi-mode alarm technology, and specially designed digital electronic balancing technology, as well as intelligent dynamic filtering technology, making the instrument operation more user-friendly.DMD-24 High-speed eddy current flaw detector64Hz～4MHzThe test bandwidth is adaptable to the detection requirements of various different metal materials, and due to the fully digital design, there's no need to realign the instruments when changing product production specifications, achieving a "dumb" operation.
DMD-24 High-speed eddy current flaw detector can be equipped with through-type coils with very low coupling gap requirements, as well as flat array probes as small as a cigarette box. The choice of probe is entirely based on the user's inspection requirements. The detection system can be equipped with a high-precision delay marking module, speed measurement device, marking machine, and an adjustable universal probe stand to achieve online automatic eddy current flaw detection. The system features synchronous alarm output with both internal and external clock control, as well as the ability to control the marking width with high precision.
