CDX-III. multi-purpose magnetic particle flaw Detector is a magnetic particle flaw detection equipment with a variety of magnetization methods. The instrument adopts thyristor as a contactless switch, which has low noise, long life, simple and convenient operation, strong applicability and stable operation. It is a new product that has been introduced recently, and in addition to all the advantages of a portable model, it also has some of the advantages of a mobile model, expanding its versatility and simplifying operation. This model is a non-contact ultra-small testing instrument. It has a variety of magnetization methods such as AC rotating magnetic field and magnetic yoke. It is a simple, reliable, lightweight, practical and effective portable multi-functional magnetic particle flaw detection instrument. Four types of probes can be selected: A, D, Ec, and O (one probe is included). In short, the instrument is a combination of a variety of flaw Detectors, with a wide range of functions, especially for the flaw detection of surface parts that are not allowed to be energized and arced.

According to the magnetic interaction between the leakage magnetic field and the magnetic particle, the shape, location, size and severity of the defect can be intuitively displayed, and the nature of the defect can be determined
The application of the new power mode improves the depth of the defect detection and the sensitivity performance of the surface inspection
Adjustable yoke spacing for maximum instrument utility
It has a power-on lighting function, which is convenient for use in low-light conditions
Equipped with four different optional magnetic probe units, it enhances the adaptability and accuracy of the measurement of different shapes of workpieces
Using a variety of magnetization methods, it is almost not limited by the size and geometry of the part, and all parts of the workpiece can be detected
The thyristor is used as the magnetizing switch, and the ergonomic design is adopted, which is convenient for the Detector to control the magnetization switch at any time when holding the probe in his hand
The inspection and flaw detection speed is fast, the process is simple, and the cost is low
Defects can be detected under the surface of the workpiece from 0.5 to 3 mm, and for larger pores, the detection depth of DC magnetization can be up to 5 mm
With extremely high detection sensitivity, the magnetic marks formed by the accumulation of magnetic particles on the defect have a magnifying effect, and the minimum width of the detection can be up to 0.1 microns
1) Horseshoe probe (type A): it can detect flaws on all kinds of fillet welds, internal and external angles of large workpieces;
2) Electromagnetic yoke probe (D type): it is equipped with a live joint, which can detect flaws on curved surfaces and flat workpieces;
3) Rotating magnetic field probe (Ec type): it can carry out one-time comprehensive flaw detection on pressure vessels such as various welds, curved surfaces of various geometric shapes, planes, pipelines, boilers, spherical tanks, etc., and can check the comprehensive defects and scars on the surface of the workpiece;
4) Magnetic ring coil (O-type): It can meet the flaw detection of circumferential cracks that can be put into the coil of all workpieces, and it is very convenient to detect the fatigue marks of the workpiece (the fatigue marks are perpendicular to the axial direction), and it can also be used to demagnetize the workpiece away from the method.
