The EMDEUS magnetic particle flaw detector is a compact device developed by EXPERT NK LLC for testing products by the magnetic method in any conditions. The flaw detector takes into account all known varieties and techniques of the magnetic particle testing method, including pulsed magnetization, DC magnetization using an electromagnet, and magnetization in a solenoid.

EMDEUS is ideal for non-destructive testing by the magnetic particle method using a constant or alternating magnetic field on ferromagnetic parts of various sizes and geometries. Providing the ability to create different types of magnetization, which allows you to achieve the highest sensitivity and excellent contrast in magnetic particle testing, both by the applied field method and by the method of residual magnetization. In this case, the controlled object is not a carrier of a magnetic field in itself, this field is organized by magnetization by currents, and interacts with the fields of magnetic particles deposited on the surface. Magnetic particles are magnetized (coagulate) and form accumulations on the surface of ferromagnetic materials, which indicate a stray field over defects, indicating with certainty the presence and location of surface and subsurface discontinuities such as flocks, shells, welding defects, grinding, hardening and fatigue cracks, etc. After the control is completed, the object is demagnetized. The properties of the human eye make it possible to see scratches on polished surfaces from 6.0 µm, and with the help of magnetic indicators with a magnetic particle size of 2.0 to 6.0 µm, the possibilities of detecting smaller defects on rougher, untreated surfaces, including welds, are significantly expanded. The effect of coagulation of magnetic particles turns defects invisible to the eye into easily detectable ones.

For maximum convenience of control, a magnetometer is built into the EMDEUS flaw detector.

Despite its small size and weight of just over 4 kg, the flaw detector has a pulsed current regulation of up to 5500 A, which allows it to be put on a par with the most powerful devices, which are an order of magnitude larger in weight.

Thanks to a convenient shoulder bag and a full range of functions, including automatic degaussing, EMDEUS turns into a convenient assistant not only in laboratory conditions, but also allows you to carry out control in hard-to-reach places.
